Abstract

The method provides a method for recovering barite from tailings. The method for recovering barite from tailings comprises the steps that a ball grinding mill is controlled to grind lead and zinc tailings, and 1950-2050 grams of zinc sulfate per ton is added into a casting material port; 95-105 grams of xanthate per ton, 295-305 grams of copper sulfate per ton and 25-35 grams of oil number two perton are added, and the mixture is mixed for conducting roughing to obtain zinc concentrate; 4900-5100 grams of glass water per ton and 290-310 grams of oleic acid per ton are added, and the mixture is stirred for conducting concentration to obtain barite. The design of adding the zinc sulfate effectively achieves the effect of an activator, the efficiency of recovering barite is increased, and the design of adding the xanthate achieves the effect of a collecting agent; the design of adding the oil number two achieves the effect of a foaming agent, the effect of separating lead from copper inthe lead and zinc tailings is further achieved effectively, and the efficiency of recovering barite is increased; the design of adding the glass water achieves the effect of an inhibiting agent, and the efficiency of recovering barite is further increased.

Description

technical field [0001] The invention relates to the technical field of tailings recovery, in particular to a method for recovering barite from tailings. Background technique [0002] The utilization of pure barite ore in our country is relatively good, but there are still a large number of associated barite ore, whose quality is generally low, and barite is not well recovered comprehensively. The industrial grade of barite mining is 50%, the cut-off grade is 30%, BaSO 4 Those with a content of less than 30% are low-grade barite ores. A lead-zinc mine in Guangxi is associated with low-grade barite, and the tailings contain BaSO after flotation of lead-zinc 4 It is only about 13%, which belongs to low-grade barite ore. At the same time, the dolomite content in lead-zinc tailings reaches 55-65%, and those with dolomite content higher than 20% belong to high dolomite content. At the same time, the tailings contain 13-15% pyrite. The flotation properties of dolomite are very ...
