Embodiment 1

[0020] Adopt inhibitor described in the present invention, carry out flotation research to certain copper sulfide in Sichuan, its main copper mineral is chalcocite, secondly bornite, chalcopyrite etc., ore copper-containing 0.86%; Other metal minerals have Pyrite; gangue minerals are mainly quartz, clay minerals (hydromica, kaolinite, etc.), carbonaceous, followed by feldspar, calcite, etc., and a small amount of viritrinite debris and organic carbon. 10.42%. The nature of the ore is complex, and the copper minerals in the ore are closely related to carbonaceous, and the ore contains a large amount of carbonaceous shale and a small amount of vitrinite. These carbons have good floatability. If flotation directly floats copper, the carbon will inevitably enter the copper concentrate and affect the product quality. Therefore, the key to solving the flotation of this ore is to effectively separate copper minerals and carbon. According to ore properties, add sodium carbonate 2000-...

Abstract

The invention discloses carbon inhibitor used in copper sulfide ore flotation and application of the carbon inhibitor, and belongs to the technical field of nonferrous metal flotation reagent application. The inhibitor is composed in the manner that the ramification of biphenyl serves as a carbophile group, and polyoxyethylene ether serves as a hydrophilic group. Through usage of the inhibitor, during copper sulfide ore flotation, carbon in the ore can be effectively restrained, consumption of carbon impurities to a collecting agent is reduced, flotation collecting of the copper sulfide ore is facilitated, and the beneficiation index of copper concentrates is improved.

Description

technical field [0001] The invention belongs to the technical field of application of nonferrous metal flotation agents, and relates to a flotation inhibitor and its application, in particular to a carbon high-efficiency inhibitor suitable for the flotation process of copper sulfide ore and its application. Background technique [0002] In flotation technology, effectively suppressing gangue minerals and effectively separating target minerals from gangue minerals is the key to flotation collection. Non-ferrous metal copper is an important industrial raw material. Most of the copper for industrial use is obtained from the flotation of copper sulfide. With the increasing demand for copper ore, copper ore resources continue to decrease. Poor, fine, and miscellaneous have become the main characteristics of copper ore. Some carbonaceous veins Stone-type copper deposits have also been gradually developed and utilized. Due to the low density of carbonaceous and strong hydrophobic...
