| description | PURPOSE:To improve the quality of recovered metal and to increase the rate of recovery by pulverizing dephosphorization slag by swelling and crumbling caused by the slaking of CaO and by recovering metal by magnetic force and compounds contg. F by treatment. CONSTITUTION:Crushed dephosphorization slag is put in a slaking tank and pulverized by swelling and crumbling caused by the slaking of CaO. Metal in the pulverized dephosphorization slag is attracted by a magnet and recovered. Ca(OH)2 in the remaining slag is removed by gravity separation and recovered. The remaining slag is then treated with an acid and filtered. CaF2 is recovered from the residue, and Ca5F(PO4)3 from the filtrate. |
