Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. The product represented by this dataset is tungsten concentrate, a high-grade tungsten-bearing mineral product obtained from tungsten raw ore through the beneficiation, enrichment and purification process, with a tungsten concentrate grade of 52.97% and a tungsten recovery rate of 80.00% in the beneficiation process; this production process simultaneously produces three valuable by-products, namely tin concentrate, copper concentrate and silver concentrate, among which the copper concentrate grade is 19.00% with a recovery rate of 76.00%, the tin concentrate grade is 23.00% with a recovery rate of 76.00%, and the silver concentrate grade is 12.66kg/t with a recovery rate of 25g/t. Tungsten concentrate has stable physicochemical properties, high hardness, high melting point, excellent high-temperature resistance and abrasion resistance. The upstream raw material of the product is tungsten raw ore; downstream it is the core raw material for smelting ferrotungsten, preparing ammonium paratungstate, metallic tungsten powder and tungsten-based cemented carbide, widely used in fields such as cemented carbide, aerospace, precision cutting tools, metallurgical and chemical industry, and military manufacturing, being the core intermediate mineral product of the tungsten metallurgy industry chain. The dataset includes the main raw and auxiliary materials, energy and waste of the production process; infrastructure such as production equipment manufacturing and plant construction 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.
