Oxidation continuous deferrization process for copper cobalt liquor

Abstract

The present invention discloses an oxidation de-ironing method of copper cobalt solution. The iron removal of the copper cobalt ores lixivium adopts the interrupted de-ironing method, which can not realize the continuous input and output of material, thereby causing the long turnover time among the equipments, reducing the effective utilization rate of the equipments, at the same time increasing the production cost and the labor strength. The present invention makes a plurality of de-ironing tanks connect in series to form a multilevel continuous de-ironing system into which the copper cobalt solution containing iron is put continuously, the copper cobalt solution is performed with the oxidation treatment firstly to make ferrous iron in the solution to be oxidized completely into ferric iron, and then the copper cobalt solution carries out the multilevel continuous iron removal, and utilizes the pipeline port fall existing between the tanks to flow into the next tank from the last tank. Through adopting the present invention, the continuous input and output of the feed liquid is realized, the production continuity is good, the automatic control is realized completely, the labour force is reduced, the working intensity is lowered, and the production efficiency is high.

Description

technical field [0001] The invention relates to a method for removing iron from a copper-cobalt ore leaching solution, in particular to a method for continuously removing iron by oxidation of a copper-cobalt solution. Background technique [0002] The current iron removal method of copper-cobalt ore leaching solution adopts intermittent iron removal method. The so-called intermittent iron removal means that the iron-containing copper-cobalt solution completes a series of reaction processes such as oxidation and neutralization in a single iron removal tank. Finally, all the materials in the iron removal tank must be transferred out at one time before they can be fed into production again. The above-mentioned intermittent iron removal method cannot realize the continuous input and output of materials, resulting in a long turnaround time for materials between equipment, reducing the The effective utilization rate of equipment, the number of equipment used is large, but also inc...
