Self-activation flotation method for component of fluid inclusion of copper sulfide ore

Abstract

The invention relates to a self-activation flotation method for a component of a fluid inclusion of a copper sulfide ore. Specific to the 'rich sulfur' state formed by surface relaxation of the copper sulfide ore, by utilizing the characteristics that copper ions released by the fluid inclusion of the copper sulfide ore have ultrahigh adsorption activity on a 'rich sulfur' surface, the copper ions of the component of the fluid inclusion are attached to a new surface of the copper sulfide ore so as to form a 'rich copper' surface, so that the adsorption activity of the surface of the copper sulfide ore to xanthate anions is increased, the self-activation flotation for the surface of the copper sulfide ore is realized, the flotation recovery of the copper sulfide ore is increased, the dosage of collecting agents is reduced and the technical and economic targets are increased.

Description

Technical field

[0001] The invention relates to a self-activation flotation method for fluid inclusion components of copper sulfide ore, and belongs to the technical field of mineral processing. Background technique

[0002] Copper sulfide ore is the main source of copper resources. Flotation is the main method for recovering copper sulfide ore. Almost 90% of copper sulfide ore is recovered by flotation. Therefore, flotation plays an important role in the recovery and utilization of copper ore resources. status. Different copper sulfide mines use different collectors according to their mineral composition. However, the most commonly used collectors for copper sulfide flotation are mainly sulfhydryl collectors such as xanthate, black medicine, and esters. There are also several kinds of collectors mixed to improve the collection effect. Compared with other minerals, copper sulfide ore has good flotability. There are relatively few researches on the process and technology to ...
