Description

Microbubble neutralizing tank device based on reaction kettle transformation

Technical Field

The utility model relates to the field of electrolytic leaching, in particular to a microbubble neutralizing tank device based on reaction kettle modification.

Background

In the electrolytic plant, for producing the crude copper, equipment microbubble neutralizing tanks are required to be added to melt the copper foil and increase the concentration of copper ions in the electrolyte. Because the chemical property of metallic copper is stable, the dissolution of copper in non-oxidizing acid liquor is difficult, and the addition of an oxidizing agent is the same way of dissolving copper at present. In the production practice, the copper dissolving equipment such as a 'neutralization tank' is used for introducing air (the cheapest oxidant) into dilute sulfuric acid to realize the dissolution of copper. It is generally considered that the dissolution of copper in acid solution with air is a typical electrochemical reaction process, and the appropriate amount of air ensures that the oxidation potential of the solution can make the reaction proceed smoothly.

In recent years, an alloy raw material containing multiple elements such as copper, cobalt, iron and the like enters the domestic market, the raw material contains more than 70 percent of copper, the rest is iron, cobalt and the like, and the alloy is slightly red after an oxide layer on the surface of the alloy is removed, and is commonly called as red alloy. The ability to hydrometallurgically treat the alloy is an ideal process and is therefore of great importance to the ability to economically and rationally complete the leaching process. The leaching equipment using the microbubble neutralization tank and taking air as an oxidant in a dilute sulphuric acid medium is an ideal technical scheme.

The red alloy is black or brownish black in an original state, and under an ideal experimental state, the red alloy can be smoothly leached in a dilute sulfuric acid medium by taking air as an oxidant, the leaching rate is more than 99.5%, and the leaching speed is higher at the leaching temperature of 75-85 ℃. The leachate has good filtering performance, filter residues are easily suspended solids, and an important component of the leachate is carbon.

The alloy dissolution in the microbubble neutralization tank is carried out according to the following formula:

.t. r (Me + Cu, Fe, Co, Ni, etc.) Me +1/2O2+ H2SO4 ═ Me2+ + SO 42- + H2O

No. (Me + Cu 2) · Cu + Me 2.. 9.. c) (Me ═ Cu, Fe, Co, Ni, etc.)

According to electrochemical reaction data, the equation reaction is easy to carry out, so that the leaching speed of the red alloy is actually determined by the leaching speed of Cu:

Cu+1/2O2+H2SO4＝Cu2++SO42－+H2O.......③

the reaction of the formula III can be rapidly carried out just the advantages of the microbubble neutralizing tank, but the conventional microbubble neutralizing tank is expensive and can only be purchased outside, and the cost is high, and on the other hand, a large amount of updated reaction kettles are idle or even scrapped in the conventional process, so that a large amount of resource waste is caused, and the technical scheme of reforming the reaction kettles into the microbubble neutralizing tank does not exist at present.
