Beneficiation method for copper-cobalt sulfide ore containing two types of cobalt-containing minerals

Abstract

The invention discloses a beneficiation method for copper-cobalt sulfide ore containing two types of cobalt-containing minerals. The method includes the following steps: a copper-cobalt activator anda selective copper-cobalt collector are added into raw ore pulp in order for copper-cobalt rough selection and copper-cobalt scavenging to obtain copper-cobalt crude concentrate and copper-cobalt scavenging tailings pulp; adding a pH regulator and a gangue mineral inhibitor into the copper-cobalt crude concentrate and carrying out copper-cobalt fine selection to obtain copper-cobalt concentrate; combining a bottom flow of the first copper-cobalt fine selection and foam of the first copper-cobalt scavenging and carrying out middling re-collection; adding a cobalt activator, a cobalt collector,a xanthate collector and a foaming agent into combined ore pulp of the copper-cobalt scavenging tailings pulp and a bottom flow of the middling re-collection-fine scavenging for cobalt rough selectionand cobalt scavenging to obtain cobalt crude concentrate; and carrying out fine selection on the cobalt crude concentrate to obtain cobalt concentrate. The beneficiation method for copper-cobalt sulfide ore containing two types of cobalt-containing minerals can effectively solve the problems that copper-cobalt mixed concentrate is low, affecting the quality of the concentrate, improves the product quality of the copper-cobalt mixed concentrate, ensures the effective recovery of copper and cobalt, and improves the value of flotation concentrate.

Description

technical field [0001] The invention relates to the technical field of copper-cobalt ore beneficiation, in particular to a beneficiation method of copper-cobalt sulfide ore containing two types of cobalt-containing minerals. Background technique [0002] Both copper and cobalt are important metal resources for the development of human society. According to the different properties of the ore, methods such as hydrometallurgy (leaching), gravity separation, flotation, and magnetic separation are mainly used to recover copper and cobalt resources in the ore. According to the different oxidation rate of ore, it can be divided into copper cobalt sulfide ore (copper, cobalt oxidation rate <10%), mixed copper cobalt ore (copper, cobalt oxidation rate <10% ~ 30%) and copper cobalt oxide ore (copper, cobalt oxidation rate <10% ~ 30%) and copper cobalt ore (copper, cobalt oxidation rate <10%) Cobalt oxidation rate >30%). Among them, sulfide copper-cobalt ore and mixed...
