Copper oxide and copper sulfide ore flotation agent and preparation method thereof

Abstract

Copper oxide and copper sulfide ore flotation agent is made with, by weight, 15-19 parts of gutter oil, 3-5 parts of silica sol, 5-7 parts of sodium naphthenate, 4-5 parts of urea, 2-3 parts of sodium carbonate, 5-7 parts of chitosan, 6-9 parts of mimosa extract, 3-4 parts of sodium metabisulfite, 2-4 parts of fatty alcohol-polyoxyethylene ether, 20-25 parts of black powder, and 4-5 parts of activator. The floatation agent with the gutter oil remains foamy, and the cost is reduced; through the use of the chitosan and silica sol, flocculation is effective and yield is increased; the flotation agent is capable of well collecting copper, copper yield is high, the flotation agent is well selective, has good inhibitory action against other ores, and copper grade is high. The activator contains the components such as jade nanopowder, is capable of stably dispersing and has good permeability and activity, the activation effect lasts long, and the yield and grade of copper is increased. The flotation agent is low in environmental pollution.

Description

technical field [0001] The invention relates to the field of mineral flotation agents, in particular to an oxidation and sulfide copper ore 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 ofte...

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
