reaction rate of reduction materials for the (ferro)silicon process

The quality of the reduction materials differs and results in different silicon recoveries. Therefore it is important to fmd a way to characterise the effect of the reduction materials on the process. Then raw materials which give optimal production, low costs and high recovery, can be chosen. The (ferro)silicon furnace may be.
