Abstract

The invention relates to a method for improving CuFeNi alloy in high nickel sulfonium, for extracting carrier CuFeNi of Pt metals from the middle product high nickel sulfonium when recycling metal Pt in nickel mineral smelt process. The invention is characterized in that the high nickel sulfonium material at 10um-1000um size and 10-40% mass density are magnetically selected at 100MT-1000MT magnetic induction. The invention has high recycle rate, and high alloy quality with low cost.

Description

technical field [0001] The method for extracting CuFeNi alloy in high-nickel matte relates to a method for extracting CuFeNi, a carrier of Pt group metal, from intermediate product high-nickel matte when metal platinum is recovered from nickel concentrate smelting process. Background technique [0002] High nickel matte is an intermediate product of the smelting process and is a man-made mineral. The phase composition of high nickel matte is: Ni 3 S 2 , Cu 2 S and CuFeNi alloy. CuFeNi alloy is used as the carrier of Pt group metals, and the effective extraction of CuFeNi alloy is the key to improve the recovery rate of Pt group metals. [0003] Separation of Ni from high-nickel matte 3 S 2 , Cu 2 The research on S and CuFeNi alloy technology originated in the 1940s. Due to the low cost of the process, it greatly simplifies the purification process of the hydrometallurgical process, and was once blocked as a technical secret. [0004] At present, the typical represen...
