crushing of metal silicon

The aluminum industry, as one major consumer of silicon metal, typically dissolves solid silicon lumps in or by liquid aluminum, thereby slowly dissolving the specifically lighter silicon in the specifically heavier aluminum. The important criteria are silicon recovery and dissolution time.

Since silicon blocks are very hard, conventionally, silicon blocks are crushed by use of a so-called jaw crusher, which is an ore crusher. At the time of crushing with a jaw crusher, a metal surface of a structural member of the crusher comes into contact with a silicon block, and a metal component from the metal surface adheres to the crushed silicon block.
