Description
The product represented by this dataset is tungsten concentrate, a high-grade tungsten-bearing mineral product obtained from tungsten raw ore through a beneficiation, enrichment, and purification process. The tungsten concentrate grade is 52.97%, and the tungsten recovery rate of the beneficiation process is 80.00%. This production process simultaneously yields three types of valuable by-products: tin concentrate, copper concentrate, and silver concentrate, of which the copper concentrate has a grade of 19.00% and a recovery rate of 76.00%, the tin concentrate has a grade of 23.00% and a recovery rate of 76.00%, and the silver concentrate has a grade of 12.66 kg/t and a recovery rate of 25 g/t. Tungsten concentrate has stable physicochemical properties, high hardness, a high melting point, high-temperature resistance, and excellent wear and abrasion resistance. The upstream feedstock of this product is tungsten raw ore, and downstream it is the core raw material for smelting ferrotungsten alloy and preparing ammonium paratungstate, metallic tungsten powder, and tungsten-based cemented carbide. It is widely used in cemented carbide, aerospace, precision cutting tools, metallurgy and chemical industry, and military manufacturing, and is the core intermediate mineral product of the tungsten metallurgy industry chain. The dataset includes the main raw and auxiliary materials, energy, and waste in the production process; infrastructure such as the manufacturing of production equipment and the construction of plants is not included within the dataset boundary. The data inventory is formed by merging data from multiple sources.

Technology comment
The production process is copper - sulfide ore flotation - tungsten-tin mixed flotation + black tungsten magnetic gravity, flotation - scheelite flotation - cassiterite gravity separation. The specific process flow is as follows: after the ore is crushed and ground, the copper sulfide ore flotation is first carried out to give priority to the recovery of copper minerals; the flotation tailings then enter the tungsten-tin combined separation stage. At this stage, tungsten-tin mixed flotation is first used to obtain tungsten-tin mixed concentrate, and the wolframite in the tailings is recovered through a combination of magnetic separation and gravity separation. Subsequently, the tungsten-tin mixed concentrate is further separated, and scheelite flotation is performed first to obtain scheelite concentrate, and then the tailings are subjected to cassiterite gravity separation to finally obtain tin concentrate.
