Problems solved by technology

[0003] The dominant collectors in the existing copper-lead ore flotation process are xanthate, cyanide, phosphate, xanthate, black drug ester, xanthate and other flotation agents, but in the actual beneficiation As a result, the design requirements cannot be met, the separation of copper and lead is not ideal, the copper content in the lead concentrate product exceeds the standard, the lead content in the copper concentrate product exceeds the standard, and the recovery rate of the concentrate is low, resulting in a waste of mineral resources

Abstract

A beneficiation agent for copper-lead flotation of copper-lead ore and a preparation method thereof, which is made of the following raw materials in parts by weight: 10-20 oleic acid, 5-8 sodium carbonate, 30-50 sodium sulfide, 10-15 sulfur, ester Xanthophyll 12‑18, carbon disulfide 20‑40, quicklime 1‑2, p-benzylamine 30‑60, activator 4‑5, phenylethyl alcohol 20‑35. The present invention has the characteristics of high sorting efficiency, high yield, less dosage, simple and reliable technological process, easy operation, etc., is suitable for the application of copper-lead flotation in copper-lead ore, and can bring good economic benefits to the copper-lead ore. benefit.

Description

technical field [0001] The invention relates to the technical field of ore dressing, in particular to a beneficiation agent for copper-lead flotation of copper-lead ore and a preparation method thereof. Background technique [0002] At present, my country's lead metal raw materials are mainly chalcopyrite, galena, sphalerite, white lead ore and so on. The mineral processing method of copper-lead ore is mainly the flotation method, and sometimes in order to improve the quality of the lead concentrate and remove impurities, the lead concentrate is then subjected to chemical beneficiation. [0003] The dominant collectors in the existing copper-lead ore flotation process are xanthate, cyanide, phosphate, xanthate, black drug ester, xanthate and other flotation agents, but in the actual beneficiation , As a result, the requirements of the design cannot be reached, the separation of copper and lead is not ideal, the copper content in the lead concentrate product exceeds the stan...
