A device for recovering barite from tailings

Abstract

The invention discloses equipment for recovering barite from tailings. The equipment comprises a ball grinding mill, an activating chamber, a bubble chamber, an inhibiting chamber, a discharging device and a control assembly comprising a processor, a liquid level sensor and an electromagnetic valve, a first liquid adding device, a second liquid adding device and a third liquid adding device are arranged at the top ends of the activating chamber, the bubble chamber and the inhibiting chamber, and 1950-2050 grams of zinc sulfate per ton is added into the first liquid adding device; 95-105 gramsof xanthate per ton, 295-305 grams of copper sulfate per ton and 25-35 grams of oil number two per ton are added into the second liquid adding device, and 4900-5100 grams of glass water per ton and 290-310 grams of oleic acid per ton are added into the third liquid adding device. 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 is achieved, and the efficiency of recovering barite is increased.

Description

technical field [0001] The invention relates to the technical field of tailings recovery, in particular to a device 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 ...
