Problems solved by technology

[0005] The purpose of the present invention is to provide a copper-cobalt wet smelting filtration and washing system and its operation mode, to solve the problem mentioned in the above-mentioned background technology that the current general medium and large enterprises in copper-cobalt smelting mainly use thickeners to filter, However, the thickener is expensive, and the consumption of equipment installation is high. The cost is high, and it is not suitable for large-scale development. Generally, small and medium-sized enterprises use filter presses. Although they can save costs, they require more equipment groups and consume more energy in operation. Large, and the workload of filter cloth cleaning and replacement is also large

Abstract

The invention discloses a copper-cobalt wet smelting filtering and washing system and its operation mode, which relate to the technical field of wet smelting. Filtering and washing tank; the inner side wall of the filtering and washing tank is fixedly provided with a slurry feeding pipe, the side of the filtering and washing tank is fixedly provided with a high-copper, low-copper, circulating lotion pipe, and the interior of the filtering and washing tank is fixed A middle partition plate is arranged, and a filter cloth is fixed on the inner side of the middle partition plate. The present invention filters the leaching slurry and performs countercurrent washing of the filter residue for many times, which can improve the washing treatment effect of the leaching residue and improve the washing efficiency of the leaching residue. The work efficiency is beneficial to reduce the cost of washing and processing the leaching residue.

Description

technical field [0001] The invention relates to the technical field of wet smelting, in particular to a copper-cobalt wet smelting filtering and washing system and an operation method thereof. Background technique [0002] Hydrometallurgy is the process of chemical treatment of metal mineral raw materials or organic solvent extraction, separation of impurities, extraction of metals and their compounds in an acidic medium aqueous solution. When extracting some minerals, traditional pyrometallurgy is not suitable, but can only be used The chemical solvent separates them, and the leaching residue needs to be filtered and washed during the copper-cobalt hydrometallurgy process. [0003] At present, the general medium and large enterprises in copper and cobalt smelting mainly use thickeners for filtration, but the thickeners have high cost, high consumption of equipment installation, high cost, and are not suitable for large-scale development. Generally, small and medium-sized en...
