Description

Technical Field

[0001] The utility model relates to the technical field of smelting equipment, in particular to an antimony electrodeposition lean liquid storage tank. Background Art

[0002] Low-grade complex antimony-containing gold concentrate (Sb≤4%) is enriched to an antimony content of ≥8% by flotation, and mixed with high-grade complex antimony-containing gold concentrate (antimony 15%~20%) to obtain a mixed ore containing 10%~15% antimony. The mixed ore is put into a high-level slurry tank, and the slurry is adjusted according to the liquid-solid ratio (1~1.5):1. The slurry flows into a closed leaching tank by gravity, and sodium sulfide and other leaching agents are added. Nitrogen is continuously introduced to replace the air in the tank. Nitrogen forms an isolation layer above the liquid level of the leaching tank, isolating the slurry from the air and inhibiting the generation of polysulfides. Steam heating is used to control the leaching temperature. The leaching residue produced is sent to the pyrometallurgical system for batching treatment after filtration and washing to recover valuable metal elements. The produced leachate is pumped to the electrolytic section. Part of the lean liquid after electrolytic deposition is sent to the slurry tank for slurry adjustment, and part of the lean liquid is sent to the storage tank for the next step of treatment. The temperature of the antimony electrodeposition lean liquid transported from the electrodeposition section to the storage tank is 30℃~40℃. It is naturally cooled in the storage tank. A small amount of crystals are precipitated after cooling. Since the bottom of the tank is set horizontally, the crystals are deposited at the bottom of the tank and are not easy to discharge. The tank needs to be cleaned, which increases the frequency of tank cleaning and low labor productivity. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an antimony electrodeposition lean liquid storage tank.

[0004] The technical solution of the utility model is achieved as follows: an antimony electrodeposition lean liquid storage tank comprises a tank body, wherein a manhole 1, an exhaust port, a liquid inlet and a liquid level gauge port 1 are arranged on the top of the tank body, a manhole 2, a pump port, a reserved port, a sewage outlet and a liquid level gauge port 2 are arranged on the outer side of the lower end of the tank body, the bottom of the tank body is filled with glass fiber reinforced plastics, the upper end face of the glass fiber reinforced plastics is an inclined surface, the inclined surface angle is 3-6 degrees, the high end is located on the second side of the manhole, and the low end is located on the sewage outlet side.
