Chalcocite flotation agents and preparation method thereof

Abstract

Chalcocite flotation agents are made of the following raw materials including, by weight, 15-18 parts of black powder, 20-24 parts of m-benzenedicarbonyl thiourea, 8-10 parts of drainage oil, 5-7 parts of ethyl alcohol, 2-4 parts of butyl acrylate, 5-7 parts of AEO, 2-4 parts of polyacrylamide, 1-2 parts of chitosan, 0.6-1.4 parts of nanometer titanium dioxide, 1-2 parts of sodium hydroxide, 1-2 parts of sodium hydrogen phosphate, 1-2 parts of boronic acid and 4-5 parts of activating agents. As the nanometer titanium dioxide is added, the chalcocite flotation agents are uniform and stable in dispersion, have stable foam and are good in flocculation effect, good in copper collecting performance, high in copper yield, good in selectivity, good in rejection capability and high in copper grade. The activating agents are stable in dispersion, good in permeability, good in activating performance, long in duration time of the flocculation effect and capable of improving the yield and grade of copper.

Description

technical field [0001] The invention relates to the field of mineral flotation agents, in particular to a chalcocite flotation agent and a preparation method thereof. Background technique [0002] At present, the raw materials of copper mineral dressing and smelting in my country are mainly chalcopyrite, chalcocite, bornite, malachite and so on. According to the technical conditions of dressing and smelting, copper ore is divided into three natural types according to the ratio of copper oxide and copper sulfide. That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% copper oxide. [0003] The collectors that occupy a dominant position in the current copper ore flotation process are flotation agents such as xanthate, thiophosphate and mercaptan, thiamine ester, xanthate, black drug ester, and xanthate. However, in the actual beneficiation, the results often fail to meet the desi...

AI Technical Summary

Problems solved by technology

[0003] The collectors that occupy a dominant position in the current copper ore flotation process are flotation agents such as xanthate, thiophosphate, mercaptan, thiamine ester, xanthate, black drug ester, and xanthate. However, in the actual beneficiation, the results often fail to meet the design requirements, and the separation of copper and sulfur often occurs unsatisfactorily, and the sulfur content in copper concentrate products exceeds the standard; in addition, the yield of copper is low, and the recovery rate of copper concentrate is low. , resulting in a waste of mineral resources
