- UrbanMines has a joint venture at South China, which specialize in crushing process pyrite ore to fine pellet. Well-known as "Oriental Pyrite City", we has been proven to have huge pyrite resource serves, ranked in the top of the world. For high value-added making full use of these rich natural resources, we stick to the corporate philosophy "quality first, win with quality ". By using unique processing methods and strictly controlling export products processing link, we can ensure that the important indicators such as sulfur content, moisture content, size and impurities are better than the user’s requirements.
- Silicon metal is extracted from quartzite, aided by the addition of wood chip and coal, in electric arc furnaces at temperatures of around 2,000 degrees Celsius. UrbanMines has another joint venture plant at Fujian Province, which is designed to produce ≥ 95% pure silicon metal from raw materials, that is, quartz and carbon; reactive coals with low ash content, wood chips, and a small amount of limestone. The plant obtains its key raw material quartzite primarily from the quarries in West Fujian Province and South Jiangxi Province China. However, the related logistical costs are more than outweighed by the advantages of electricity procurement from Sate Grid Corporation of China. And the dust emissions generated during silicon metal production are almost completely removed from the ambient air by high-performance filter systems installed in the plant. With silicon metal production at UrbanMines’joint venture plant powered entirely by renewable energy within near futhure, the overall CO2 footprint of the whole process is drastically reduced. Taken as a whole, therefore, the production process offers exceptional sustainability credentials. The vast majority of the raw material is converted into silicon metal, so the production process generates very few solid by-products. A small part of the raw material is also obtained in the form of slag.
- The history of UrbanMines goes back more than 15 years. It started with the recycling activities of nonferrous scrap and rare metals. We devote to reduce the volume of unrecyclable waste and makes it non-polluting by acting as coordinator between the discharging plants and processing plants. Leveraging a nationwide and Asian network, we collect native polycrystalline silicon materials, rare metal scrap and other valuable metallic waste and recycle them as raw materials.

Silicon Metal
Silicon metal is commonly known as metallurgical grade silicon or metallic silicon because of its shiny metallic colour. In industry it is mainly used as an aluminium alloy or a semiconductor material. Silicon metal is also used in the chemical industry to produce siloxanes and silicones. It is considered to be a strategic raw material in many regions of the world. The economic and application significance of silicon metal on a global scale continues to grow. Part of the market demand for this raw material is met by a producer and distributor of silicon metal – UrbanMines.

Mineral Pyrite(FeS2)
UranMines produce and process pyrite products by flotation of primary ore, which is high quality ore crystal with high purity and very little impurity content. In addition, we mill the high quality pyrite ore into powder or other required size, so as to guarantee the purity of sulphur, few harmful impurity, demanded particle size and dryness.Pyrite Products are widely used as resulfurization for free cutting steel smelting and casting furnace charge, grinding wheel abrasive filler, soil conditioner, heavy metal waste water treatment absorbent, cored wires filling material, lithium battery cathode material and other industries. Ratification and favourable comment having got users globally.
