metal silicon slag

Silicon metal slag has long been used to pave roads or fill pits as waste slag, resulting in waste of resources, occupying a lot of land resources and wasting a lot of manpower and material resources. Therefore, the development of a simple, low-cost, green and environmentally friendly method for re-extracting metal silicon from silicon metal slag can realize the reuse of precious resources and create considerable economic value at the same time. The method for re-extracting metal silicon from metal silicon slag can effectively extract metal silicon with a silicon content of more than 99% from metal silicon slag. The operation is simple, the cost is low, and resources are reused, so as to overcome the inability of the existing metal silicon slag. Lack of effective utilization. By adding specific auxiliary materials and a specific smelting process, metal silicon products with a Si content of more than 99% can be obtained, exceeding the inspection standard of 98% metal silicon, the quality of the finished products is good, and the market prospect is good. The method has simple operation and low cost, realizes the reuse of resources, changes the phenomenon of metal silicon slag paving and pit filling for many years, and the production process is green and environmentally friendly. It is a good method for energy saving and emission reduction in the silicon industry, and has important social and economic implications.
