Problems solved by technology

[0002] my country's nickel ore resources are mainly low-grade copper-nickel sulfide ores rich in MgO silicate gangue minerals, such as serpentine, talc, chlorite, tremolite, etc., these magnesium-rich silicate minerals in the flotation process Among them, not only the mudification is serious, but also the floatability is excellent after itself or "heterogeneous coagulation", which seriously interferes with flotation and brings difficulties to the subsequent concentrate smelting
[0003] For a long time, around the problem of magnesium reduction in copper-nickel sulfide ore flotation concentrates, engineering and technical personnel from relevant universities, research institutes, and factories and mines at home and abroad have done a lot of research work, and have also developed sodium carboxymethyl cellulose (CMC), water glass, sodium hexametaphosphate, sodium humate, tannic acid, tannic acid and other flotation inhibitors of magnesium-rich silicate minerals, but practice shows that the effect of these inhibitors is not ideal

Abstract

The invention provides a magnesium-silicate-rich mineral floatation inhibitor. The inhibitor comprises the following ingredients in part by weight: 2 to 30 parts of mannan, 5 to 25 parts of sodium gluconate and 5 to 15 parts of sodium tripolyphosphate. The mannan is one of konjac glucomannan and aloe mannan. The invention also provides a method of preparing the inhibitor. The invention also provides application of the inhibitor in inhibiting the magnesium-silicate-rich minerals in a floatation process.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a magnesium-rich silicate mineral flotation inhibitor and a preparation method and application thereof. Background technique [0002] my country's nickel ore resources are mainly low-grade copper-nickel sulfide ores rich in MgO silicate gangue minerals, such as serpentine, talc, chlorite, tremolite, etc., these magnesium-rich silicate minerals in the flotation process Among them, not only the mudification is serious, but also the buoyancy of itself or after "heterogeneous coagulation" is excellent, which seriously interferes with flotation and brings difficulties to the subsequent concentrate smelting. [0003] For a long time, around the problem of magnesium reduction in copper-nickel sulfide ore flotation concentrates, engineering and technical personnel from relevant universities, research institutes, and factories and mines at home and abroad have done a...
