簡介
Hebei Jinglong Mining Co., Ltd. (Chinese: 河北京龙矿业有限公司) is a Chinese producer and processor of non-metallic mineral materials used across construction, plastics, rubber, coatings, ceramics, filtration, and other industrial applications. Founded in 2000, the company is based in the Ciheqiao Industrial Zone of Lingshou County, Hebei Province, at the western foothills of the Taihang Mountains.
The company integrates mineral-product procurement, processing, manufacturing, and sales. Its portfolio includes quartz sand and powder, mica powder, feldspar powder, vermiculite, sillimanite, colored sand, synthetic mica, and related mineral products. Company information describes more than 100 products across five principal series, with particular emphasis on fine and ultrafine powders.
Within the plastics industry, Hebei Jinglong occupies a position in the upstream mineral-additives segment rather than in polymer production or plastics processing. Its materials can contribute mineral reinforcement, dimensional stability, surface effects, rheological control, heat resistance, and cost optimization in polymer compounds, masterbatches, coatings, adhesives, sealants, and construction-related plastics.
History and Development
Hebei Jinglong was established in 2000 and developed from the former Hebei Iron Ore Dressing Plant. Its subsequent expansion reflected the broader industrial development of Lingshou County, an area associated with non-metallic mineral resources and mineral-processing enterprises.
Key development milestones include:
- 2000: Establishment of the company and transition from its predecessor operation into a broader mineral-products business.
- Production-line expansion: Development of integrated mineral-processing lines capable of producing quartz, mica, feldspar, vermiculite, sillimanite, and other non-metallic materials.
- Process-control investment: Introduction of German-made computerized hydraulic classification and testing equipment, described by the company as an investment of approximately RMB 2.5 million.
- International market development: Expansion of sales beyond Hebei into several Chinese provinces and export markets including Japan, South Korea, and the United States.
Public company descriptions give different dates for certain registration details, but consistently identify 2000 as the operating foundation of the business and describe its core activity as non-metallic mineral production and processing.
Business Operations and Segments
Hebei Jinglong’s activities are organized around the conversion of mined or purchased mineral feedstocks into processed powders, granules, and other industrial mineral products. Its operating model combines:
- Mineral-material acquisition and sourcing
- Crushing and size reduction
- Grinding and powder preparation
- Hydraulic classification and particle-size control
- Screening and product separation
- Product testing and quality inspection
- Packaging and domestic and export distribution
The company reports an industrial site of approximately 150,000 square metres, investment of about RMB 12 million, and a workforce of more than 120 employees, including management personnel and engineers.
Its business is relevant to plastics manufacturers because mineral fillers and functional additives are commonly selected according to particle size, morphology, chemical composition, moisture content, whiteness, hardness, and compatibility with the polymer matrix. Consistency in these characteristics affects extrusion stability, dispersion, surface appearance, mechanical performance, and processing economics.
Products and Technologies
Quartz products
Quartz sand and quartz powder form a major part of the company’s portfolio. In plastics and rubber compounds, finely processed silica-rich minerals may be used as fillers or functional mineral components. Depending on particle size and treatment, quartz-based materials can influence stiffness, dimensional stability, abrasion resistance, thermal behavior, and surface characteristics.
Potential plastics-related uses include:
- Filled thermoplastics
- Thermoset compounds
- Electrical and electronic encapsulation materials
- Coatings and adhesives
- Artificial stone and polymer-modified construction products
The suitability of quartz for a specific polymer application depends on purity, particle-size distribution, surface chemistry, and dispersion performance.
Mica products
Mica powder is used in a range of industrial formulations because of its plate-like particle morphology, electrical insulation characteristics, heat resistance, and ability to contribute to barrier and dimensional properties. In plastics, mica can be incorporated into selected compounds where stiffness, reinforcement, electrical performance, or reduced thermal expansion is required.
Mica-containing polymer systems may be relevant to:
- Automotive components
- Electrical housings and insulation parts
- Appliances
- Construction panels and profiles
- Coatings and sealants
The performance of mica-filled compounds depends strongly on aspect ratio, particle orientation during processing, loading level, and interfacial adhesion.
Feldspar powder
Feldspar is used principally as a mineral filler and fluxing material in ceramics, glass, coatings, and construction products. In polymer-related applications, feldspar-based fillers may support hardness, dimensional control, and formulation cost management, although the appropriate grade depends on polymer chemistry and processing conditions.
Vermiculite
Vermiculite is a layered mineral that can be expanded through controlled heating. Expanded vermiculite is lightweight and possesses thermal and acoustic insulation characteristics. It is more commonly associated with construction, insulation, horticultural, and fire-resistant products than with conventional high-volume thermoplastic compounding, but it can be relevant to polymer-modified building materials and specialty formulations.
Sillimanite
Sillimanite is an aluminosilicate mineral valued for thermal stability and refractory applications. Processed sillimanite products may serve ceramic, refractory, and high-temperature industrial markets. In plastics, the material is more likely to be considered for specialized heat-resistant or mineral-filled systems than for general-purpose polymer compounds.
Colored sand and specialty mineral products
The company’s English-language product information also lists natural colored sand, synthetic mica, Venus stone, and dry-mixed mortar among its product categories. These materials extend the business beyond conventional industrial fillers into decorative, architectural, construction, and specialty-material markets.
Processing capabilities
The company describes a production system incorporating computerized hydraulic classification and testing equipment. Hydraulic classification separates mineral particles according to settling behavior and density-related characteristics, enabling closer control of particle-size fractions than simple mechanical screening alone.
For plastics applications, relevant technical considerations include:
- Particle-size distribution and fine-particle content
- Moisture control
- Mineral purity and color
- Particle morphology
- Bulk density and flowability
- Dispersion in the polymer matrix
- Compatibility with coupling agents or surface treatments
Publicly available company descriptions do not establish that every product is surface-modified, silane-treated, or specifically compounded for a particular polymer family. Buyers therefore generally need to match individual grades with the requirements of polypropylene, polyethylene, polyamide, PVC, thermosets, elastomers, or other matrices.
Applications and End Markets
Hebei Jinglong serves a mixture of mineral-consuming industrial sectors. Its products are associated with:
- Plastics and rubber compounding
- Paints, coatings, and pigments
- Adhesives and sealants
- Ceramics and glass
- Refractories
- Construction materials and dry-mix mortar
- Artificial stone and decorative products
- Insulation and fire-resistant materials
- Filtration and other mineral-processing applications
In plastics, the company’s materials can participate in several formulation strategies:
| Application area | Possible mineral function |
|---|---|
| Filled thermoplastics | Stiffness, dimensional stability, density adjustment, and cost control |
| Electrical plastics | Insulation, thermal stability, and controlled filler loading |
| Automotive compounds | Reinforcement and reduction of thermal expansion in selected formulations |
| PVC products | Filler contribution to rigidity, processing economics, and surface properties |
| Coatings and sealants | Rheology, barrier behavior, texture, and mineral content |
| Polymer-modified construction materials | Bulk, reinforcement, thermal behavior, and surface effects |
The final performance of a mineral-filled plastic depends on more than the mineral itself. Compounding temperature, screw design, residence time, moisture, filler loading, coupling chemistry, and dispersion quality all influence the finished product.
Global Presence and Market Position
Hebei Jinglong is located near road transport and reports a distance of approximately five kilometres from the Shuozhou–Huanghua railway system, providing access to domestic distribution channels. The company identifies sales to Beijing, Tianjin, Henan, Shandong, and Shaanxi, in addition to markets within Hebei.
The company also reports exports of quartz sand, quartz powder, mica powder, and related products to Japan, South Korea, and the United States. These markets connect the company with international supply chains for mineral fillers and industrial raw materials.
Its competitive position is shaped principally by:
- Proximity to mineral resources in Hebei
- Product breadth across several non-metallic mineral categories
- Ability to offer multiple particle-size grades
- Integrated processing and distribution
- Access to domestic industrial centers and export logistics
- Use of automated classification and testing equipment
The non-metallic mineral sector is fragmented and application-specific. Competition typically depends on consistency, delivered cost, technical support, logistics, regulatory compliance, and the ability to provide grades suitable for particular formulations rather than on mineral production volume alone.
Research and Development
Hebei Jinglong’s public company information emphasizes process equipment, product variety, and ultrafine-powder production. It describes ultrafine powders as products processed using advanced technology and equipment.
Research and development priorities relevant to the company’s markets include:
- Narrower particle-size distributions
- Improved classification efficiency
- Lower moisture and impurity levels
- Better batch-to-batch consistency
- Development of application-specific grades
- Improved dispersion in polymer and coating systems
- Mineral surface treatment and coupling-agent compatibility
- More efficient grinding and separation
For plastics customers, future technical differentiation is likely to depend on the company’s ability to supply not merely generic mineral powders but controlled grades with documented performance in specified polymer systems.
Sustainability and Environmental Considerations
Mineral processing has an environmental profile that includes land disturbance, energy consumption, dust generation, noise, water use, transportation emissions, and management of process residues. These factors are particularly relevant to grinding and classification operations, where electricity consumption and particulate control can affect both environmental performance and operating cost.
Mineral fillers can also support resource-efficiency strategies in plastics by partially replacing polymer resin, reducing formulation cost, and modifying stiffness or dimensional performance. However, filler use can increase product density and may affect recycling economics, melt filtration, mechanical properties, and end-of-life sorting. The overall environmental result therefore depends on the full product life cycle rather than on filler substitution alone.
Public descriptions of Hebei Jinglong identify production equipment and processing capabilities but do not provide a detailed, independently verified account of emissions performance, energy intensity, water recycling, greenhouse-gas targets, or formal circular-economy programs. Environmental evaluation consequently requires product- and facility-specific documentation, including applicable permits, testing records, and customer compliance information.
Financial Performance and Economic Impact
The company reports investment of approximately RMB 12 million, an operating area of about 150,000 square metres, and annual production capacity of approximately 200,000 tonnes. Publicly available company information does not provide a detailed series of revenue, profit, export-value, or segment-level financial results.
Its economic contribution is associated with:
- Mineral-resource processing in Lingshou County
- Employment of more than 120 people
- Demand for transportation, maintenance, packaging, and industrial services
- Supply of mineral raw materials to manufacturers in northern China
- Participation in export supply chains for quartz and mica products
For the plastics sector, the company’s economic role lies in supplying upstream filler and functional-mineral inputs to compounders, processors, coating producers, and construction-material manufacturers.
Quality Management and Certifications
Hebei Jinglong states that its products have been recognized as qualified products by the former Chinese State Building Materials Bureau and emphasizes computerized classification and testing equipment.
Quality control for mineral products generally involves evaluation of:
- Chemical composition
- Particle-size distribution
- Moisture content
- Whiteness and color
- Bulk density
- Residue on sieve
- Loss on ignition
- Magnetic or metallic impurities
- Heavy-metal content where relevant
- Consistency between production batches
For plastics applications, customers may also require documentation concerning restricted substances, traceability, packaging cleanliness, and compatibility with sector-specific regulations. The public materials reviewed do not establish a complete list of current third-party management-system certifications, so certification status should be verified for the specific product and purchasing contract.
Innovations and Future Outlook
Hebei Jinglong’s development prospects are connected to several structural trends in the plastics and mineral-products industries:
- Rising demand for mineral-filled polymers in automotive, electrical, construction, and consumer-product applications
- Greater use of lightweighting and performance-oriented fillers
- Increased demand for narrow particle-size distributions and consistent supply
- Growth of specialty coatings, adhesives, sealants, and polymer-modified building materials
- Pressure to reduce energy use, dust emissions, and transport intensity
- Increased customer scrutiny of product traceability and environmental compliance
The company’s existing emphasis on ultrafine powders, automated classification, and a broad product portfolio provides a basis for moving toward more specialized grades. Further differentiation would depend on application testing, surface modification, digital quality control, energy-efficient processing, and stronger technical collaboration with compounders and plastics processors.
The main strategic challenges include volatility in mineral demand, transportation costs, environmental requirements, competition from other Chinese mineral processors, and the technical difficulty of achieving reliable dispersion and performance across different polymer systems.
