| Abstract: | It is rather hard to process the low-grade nickel ore of No.2mining area in Jinch-an which contains lowgrade nickel and copper,high-grade magnesia.The weak-acidic medium mineral processing is used to process the ore to produce nickel and copper concentrate.The recovery of nickel and copper are80.20%and84.25%,and the concentrate grade of nickel,copper and magnesia are6.55%,4.04%and4.24%,in which cobalt,sulfide,gold,silver and platinum are also recovered. |
