Microbubble oxidization and acid dissolution method for copper-cobalt alloy

Abstract

The invention discloses a microbubble oxidization and acid dissolution method for copper-cobalt alloy. The current commonly used copper-cobalt alloy wet-process treatment method has the defects of low reaction speed, low efficiency, high cost, large equipment investment and the like. The technical scheme adopted by the invention is that dilute sulfuric acid is used as solvent and air is used as oxidant under normal temperature and normal pressure, a reaction device is formed by a centrifugal pump, a liquid-air injection pump and an acid dissolution reactor, the dilute sulfuric acid enters the acid dissolution reactor from the centrifugal pump through the injection pump, air is sucked in by using negative pressure generated when the injection pump injects high-speed liquid flow, the air is dispersed in the dilute sulfuric acid to form emulsion and to generate a large amount of oxygen-enriched microbubbles, and the microbubbles participate in the oxidization and acid dissolution reaction of the copper-cobalt alloy and the dilute sulfuric acid. The microbubble oxidization and acid dissolution method has the advantages that the dissolution speed is high, the dissolution rate is high, the fine grinding is not required for the alloy water quenching particles, the energy consumption is low, the dissolution cost is low, the air utilization ratio is high, no environmental pollution is caused and the like.

Description

Microbubble Oxidation and Acid Dissolution Method of Copper-Cobalt Alloy technical field The invention relates to a microbubble oxidation acid dissolution method for copper-cobalt alloy. Background technique The main components of copper-cobalt alloy are cobalt, copper and iron. Due to the difference in copper content, there are red alloy and white alloy. Red alloy refers to copper-cobalt alloy with high copper content. The ratio of copper, cobalt and iron in white alloy is roughly 1:1:1 or fluctuates in this range. At present, there are generally two treatment methods for copper-cobalt alloys, one is combined with fire method and humidification method, and the other is full wet method. Depending on the copper content, the selected treatment method is also different. Alloys with high copper content are generally blown into anode copper by fire pretreatment, and then electrolyzed to obtain electrolytic copper. Cobalt is recovered from blowing slag by wet treatment. Allo...
