Abstract

The invention provides a gangue depressor for flotation of high-magnesium and low-nickel polymetallic ore. The gangue depressor solves the problems that nickel and copper nickel-copper concentrate obtained by means of an existing gangue depressor for flotation of the high-magnesium and low-nickel polymetallic ore are in a low grade, the recovery rate of nickel and copper is low, and the content of a magnesium impurity oxide is high. The gangue depressor comprises, by weight, 10 parts of sodium silicate, 1-7 parts of carboxymethyl cellulose (CMC), 0.2-1.5 parts of guar gum and water, wherein the weight of the water is nine to ninety-nine times that of the total weight of the raw materials.

Description

Technical field: [0001] The invention relates to a flotation reagent used for mineral processing in the nonferrous metal industry, in particular to a gangue inhibitor for flotation of high-magnesium-nickel-poor polymetallic ores. Background technique: [0002] When the flash furnace smelts nickel sulfide concentrate, the high melting point substance magnesium oxide is often combined with FeO, Mg 2 SiO 4 and Fe 2 SiO 4 A continuous solid solution is formed, and as the content of magnesium oxide increases, the melting point of slag increases and the viscosity increases. If the magnesium oxide content in the nickel sulfide concentrate is high, the melting point of the slag rises rapidly; when the magnesium oxide exceeds a certain amount, the nickel sulfide concentrate cannot be melted and accumulates in the smelting furnace, which is extremely unfavorable to the smelting process. Therefore, in order to reduce the content of magnesia entering the flash furnace, magnesia shou...
