Efficient copper-cobalt oxide ore combination collecting agent and copper oxide ore beneficiation method

Abstract

The invention discloses an efficient copper-cobalt oxide ore combination collecting agent and a copper oxide ore beneficiation method. The combination collecting agent comprises the following components in parts by weight: 50-120 parts of benzoyl acetone, 150-360 parts of phosphoric acid styrene and 150-360 parts of butyl xanthate. The beneficiation method has the following steps: classifying theraw ore in advance, thus products with the total degree of fineness less than 0.074mm take up 65-75% finally; carrying out floatation on products together, carrying out floatation on sulfide ore firstly, carrying out floatation on ore oxide then; adding a regulating agent and an inhibiting agent for size mixing in advance, thus the ore pump concentration is 20-25% under the condition of alkalescency; and then adding the combination collecting agent, and carrying out floatation after stirring for two minutes, thus copper oxide concentrate products are obtained. The combination collecting agentand the method have the characteristics of good selectivity, less medicament dosage and high recovery rate.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a beneficiation process of copper oxide ore and a method for improving the beneficiation index of copper oxide ore. Background technique [0002] China is a resource-rich country, and it is also a resource-consuming country. Many Chinese are proud of their vast land and abundant resources. However, the per capita possession of mineral resources in our country is less than half of the world's average level. Reserves are seriously insufficient, especially copper resources are very scarce, largely dependent on imports. [0003] Copper oxide beneficiation is one of the recognized problems in the beneficiation industry, and it is also an important research field for beneficiation workers. Copper oxide ore is an important part of the world's copper resources, with abundant reserves. Most sulfide deposits have oxidation zones in the upper part. Some deposits are oxidized a...
