ABSTRACT:
There is disclosed a compacted unit of metallurgical grade granular material selected from silicon and ferrosilicon comprising a compressed homogeneous mixture of a fine powder of a silicon material selected from the group consisting of silicon and ferrosilicon, said silicon material being finer than 160 .mu.m, from 2 to about 5% by weight of the silicon material of sodium or calcium bentonite and from 2 to about 5% by weight of the silicon material of sodium or calcium lignosulfonate. The novel compacted units are useful for use in industrial processes requiring substantially pure silicon or ferrosilicon.
