Mirabilite ore leaching liquid preparation system

Abstract

The invention discloses a mirabilite ore leaching liquid preparation system. The mirabilite ore leaching liquid preparation system comprises a crushing pulping subsystem and a leaching liquid preparation subsystem, the leaching liquid preparation subsystem comprises a leaching unit, a dilution washing unit and a baume degree adjusting unit; the leaching unit comprises at least two radial flow thickeners X, a three-way change-over valve A, a three-way change-over valve B, a three-way change-over valve C and a three-way change-over valve D; a slurry suction pump X is arranged in the radial flowthickener X; the radial flow thickener X is connected with the crushing pulping subsystem through the three-way change-over valve A, and the radial flow thickener X is connected with a water supply system through the three-way change-over valve B; the radial flow thickener X is connected with the baume degree adjusting unit through the three-way change-over valve C; one end of the slurry suction pump X is connected with a sedimentation tank of the radial flow thickener X, and the other end is connected with the dilution washing unit through the three-way change-over valve D; the multiple radial flow thickeners are arranged in parallel for alternate work, the problem of a traditional intermittent operation mode is solved, continuous operation can be achieved, and the operation capacity is greatly improved.

Description

Technical field[0001]The invention belongs to the technical field of mine beneficiation and hydrometallurgy, and particularly relates to a glauberite ore leaching liquid production system.Background technique[0002]Glauber's salt is a kind of sulfate Glauber's salt mineral, which generally contains sodium sulfate, sodium oxide and magnesium sulfate. It is widely used in medicine, metallurgy, chemical industry, construction and other fields. The production of Glauber's salt generally includes two processes, brine leaching, distillation dehydration, and leaching residue management. The production and purification of brine determine the quality and production cost of Glauber's salt, which are the core technical sections. The current domestic traditional mirabilite brine preparation process is :[0003]1. Heap leaching process:[0004]1.1. Open-air heap leaching: Heap leaching conditions are composed of heap leaching site, catchment channel, and night immersion pond. The soil foundation of t...

Problems solved by technology

[0009] For example, the heap leaching process has the advantages of large processing capacity and low leaching production cost, but its leaching rate is low, and the leaching residue (liquid) entrainment loss is large, which is an extensive process; the tank leaching process: the advantage is that the leaching rate is relatively low. High, the disadvantage is that the processing capacity is small, the leaching slag (liquid) entrainment loss is large, and continuous operation is not possible; stirring leaching process: the advantage is that the leaching rate is high, but the disadvantage is that the year-on-year production capacity is low, the production cost is high, and continuous operation is not possible
