Leaching method of chalcopyrite

     

The leaching method of chalcopyrite belongs to the field of wet metallurgy technology, which includes the following steps:

1) Mixing chalcopyrite with alkali and smelting to obtain pre treated chalcopyrite;

2) Mix the pre treated chalcopyrite obtained in step 1) with acid solution, catalyst, and oxidant for oxidation leaching to obtain a copper containing leaching solution.

Firstly, alkali is used to melt chalcopyrite, causing changes in its lattice structure, making copper leaching easier, and reducing the leaching temperature for subsequent leaching; Adding catalysts and oxidants during the acid leaching process further reduces the leaching temperature, shortens the leaching time, and improves the leaching rate of copper. The results of the implementation example show that the leaching method provided by the present invention has a leaching temperature of 75 ℃ and a leaching time of 2 hours, and the leaching rate of copper reaches over 99.9%.
