Abstract

The invention discloses an efficient inhibitor composition for copper-sulfur separation and a copper-sulfur separation flotation method by applying the same. The inhibitor composition (XKY-03) comprises, by mass percentage, 55-70% of sodium humate, 20-35% of potassium permanganate and 5-10% of sodium thioglycollate; and a preparation method of the inhibitor composition (XKY-03) comprises the stepsof taking a beaker as a container at normal temperature and normal pressure, and stirring for 40-50 minutes by a magnetic stirrer. According to the inhibitor composition (XKY-03) prepared by the preparation method, the copper-sulfur separation can be effectively realized, the sulfur-iron ore which is activated by Cu2+ can be inhibited, the grade and the recovery rate of copper in the copper concentrate can be improved, meanwhile, the complexation reaction can occur between the inhibitor composition (XKY-03) and unavoidable ions in the ore pulp such as Cu2+, Pb3+, Fe3+ and the like, so that the concentration of the unavoidable ions in the ore pulp is reduced, and the activation effect of the unavoidable ions on the pyrite ore is reduced; and additionally, the inhibitor composition (XKY-03)further has the characteristics of less use amount, low toxicity and the like, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of mineral metallurgical processing, in particular to a copper-sulfur separation high-efficiency inhibitor composition and a copper-sulfur separation flotation method thereof. Background technique [0002] As an important strategic resource in the process of industrialization, copper ore resources occupy an important position in my country's mineral resources. The basic reserves of copper resources in my country account for 6.70% of the world's total basic reserves of copper resources, ranking third in the world, second only to Chile and the United States. From the type of ore, my country's copper ore is dominated by sulfide ore. Among the proven reserves of copper resources, sulfide ore accounts for 87%, oxide ore accounts for 10%, and mixed ore accounts for only 3%. my country's copper resources mainly have the following characteristics in terms of deposit scale, ore properties, ore optionality, and deve...
