Molten silicon metal is regularly tapped from the furnaces into crucibles and transferred to the casthouse where it is refined and cast into ingots. After cooling, the ingots are pre-crushed and stored temporarily within the furnace building. The product is later taken to crushing.

Silicon metal is a grey and lustrous semi-conductive metal that is used to manufacture steel, solar cells, and microchips. Silicon is the second most abundant element in the earth''s crust (behind only oxygen) and the eighth-most common element in the universe. Nearly 30 percent of the weight of the earth''s crust can be attributed to silicon.

The remaining silicon metal and the other dissolved metals in the acid solution are successively treated by electrolysis (13). Silver and copper are recovered, both with an efficiency of 95%. The electrolysis also emits NO x gases at the anode of the electrolysis (estimated in 2 kg per ton of PV waste treated).

Silicon-aluminum alloys tend to have relatively low strength and ductility, so other metals, especially magnesium and copper, are often added to improve strength. In the chemicals industry, silicon metal is the starting point for the production of silianes, silicones, fumed silica, and semiconductor-grade silicon.

Silicon metal is made by heating common sand and coke in a furnace. For most of this century, the price of it has ranged between about 8,000 and 17,000 yuan ($1,200- $2,600) a ton. Then producers in Yunnan province were ordered to cut production by 90% below August levels from September through December amid electricity curbs.
