System and method for comprehensive utilization of copper mine chats

Abstract

The invention discloses a system for comprehensive utilization of copper mine chats. The system comprises an ore crushing part, a first ore grinding part, copper-molybdenum mixing and scavenging dressing equipment, a second ore grinding part, copper-molybdenum concentrating equipment and a copper-molybdenum separating and scavenging equipment, wherein the ore crushing part is suitable for crushing ores, and the granularity of the crushed ores is 1-12mm; the first ore grinding part is suitable for grinding the crushed ores of the ore crushing part so as to obtain the ground ores with the overflow granularity of 60-200 meshes; the copper-molybdenum mixing and scavenging dressing equipment is suitable for selecting crude copper-molybdenum ores from the ores ground by the first ore grinding part; the second ore grinding part is suitable for further grinding the crude copper-molybdenum ores selected by the copper-molybdenum mixing and scavenging dressing equipment; the copper-molybdenum concentrating equipment is suitable for floating copper-molybdenum concentrates in the crude copper-molybdenum ores ground by the second ore grinding part; and the copper-molybdenum separating and scavenging equipment is suitable for further floating the copper-molybdenum concentrates floated by the copper-molybdenum concentrating equipment so as to separate molybdenum concentrates and copper concentrates. The invention further discloses a method for the comprehensive utilization of the copper mine chats.

Description

field of invention [0001] The invention relates to the field of comprehensive utilization of waste rocks in copper mines, in particular to a system and method for comprehensive utilization of waste rocks in copper mines. Background technique [0002] In the field of mining, for the waste rock left after mining, because the content of various metals contained therein is very low, the waste rock is usually discarded directly at the initial stage of mining. With the development of mining technology, it has been found that it is economically feasible to extract metals from these waste rocks, and the mining rate of the mine has been greatly improved. [0003] Currently there are various methods for recovering various metals from waste rocks. For example, a copper-molybdenum symbiotic tailings re-election process is disclosed in the patent document CN101195107, wherein classification, grinding, stirring, flotation The process enables effective recovery of copper and molybdenum in...
