Abstract

The application provides a system and method for recovering main and associated elements from sulfide ore, belonging to the technical field of non-ferrous metal smelting. The iron leaching system includes a first reactor and a second reactor; the first reactor is used to make low nickel matte, the liquid produced by the second reactor and H 2 The S cycle gas reacts under the environment of pH=4.5-7; The second reactor is used to make acid solution, the solid produced by the first reactor, the crystallized ferrous sulfate mother liquor and the H produced by the first reactor 2 The S cycle gas reacts in the environment of pH<3. The nickel and cobalt leaching system includes a third reactor and a fourth reactor; the third reactor is used to make the solid produced by the second reactor, the liquid produced by the fourth reactor and the H 2 S cycle gas reaction; the fourth reactor is used to make the electrolysis tail liquid, the solid produced by the third reactor and H 2 S cycle gas reaction. It can improve the separation effect of nickel and cobalt in low nickel matte, and the recovery effect is better.

Description

technical field [0001] This application relates to the technical field of non-ferrous metal smelting, in particular, to a system and method for recovering main and associated elements from sulfide ores. Background technique [0002] The traditional smelting process of copper-nickel sulfide ore is firstly through matte smelting to enrich iron, nickel, cobalt and copper in the form of sulfide to form low nickel matte, and the associated precious metals are also enriched. In the prior art, the separation rate of nickel and cobalt in low nickel matte is relatively low. Contents of the invention [0003] The purpose of this application is to provide a system and method for recovering main and associated elements from sulfide ore, which can improve the separation effect of nickel and cobalt in low-matte nickel. [0004] In the first aspect, the embodiment of the present application provides a system for recovering main and associated elements from sulfide ore, including an iron...
