Gangue inhibitor of high-argillization low-grade skarn copper molybdenum ore

Abstract

The invention provides a gangue inhibitor of high-argillization low-grade skarn copper molybdenum ore, and belongs to the field of copper-molybdenum separation flotation for skarn copper molybdenum ore. The gangue inhibitor comprises the following substances by mass percent: 85% to 95% of water glass, 0.1% to 1% of carboxymethyl cellulose, 1% to 5% of sodium fluoride and 1% to 10% of sodium metabisulfite. The preparation concentration of the inhibitor is 0.1% to 1%, stirring time is larger than or equal to 30 min, and dosage is 2 kg / t to 4 kg / t. The gangue inhibitor has the advantages that water glass, carboxymethyl cellulose, sodium fluoride and sodium metabisulfite are combined into inorganic colloid, the gangue inhibitor has a good inhibition function on high-argillization gangue minerals like calcite, wollastonite, dolomite, quartz and silicate during the practice process, a preparation method is easy and convenient, cost is low, muddy gangue minerals during the copper-molybdenum separation flotation process can be effectively inhibited, and the grade of molybdenum concentrate is improved.

Description

technical field [0001] The invention relates to the field of copper-molybdenum separation flotation for skarn-type copper-molybdenum ore, in particular to an inhibitor used for suppressing argillaceous gangue minerals in the process of copper-molybdenum separation flotation and improving the grade of molybdenum concentrate. Background technique [0002] In my country, molybdenum resources are extremely rich, accounting for about 37% of the world's total. At present, with the development of economic construction, the demand for copper and molybdenum is increasing. However, copper and molybdenum resources have many lean ores and few rich ores, serious co-association, many other useful components, fine particle size, and molybdenite and molybdenite. The similar buoyancy of copper sulfide ores makes it difficult to separate copper and molybdenum. Therefore, the research and application of copper-molybdenum separation technology is particularly important. [0003] Especially fo...
