Acid Leaching – Copper Ore Treatment Method
PREPARATION OF THE COPPER ORE. This study is limited in general to percolation leaching as it is the most widely used method to give proper contact of solvent with the ore to effect extraction of the copper. One of the important factors in percolation leaching is the size reduction necessary for copper recovery within reasonable time limits.MORE INFO
Effect of Pretreatment on Leaching Primary Copper Sulfide ...
The aim of this study was to improve the dissolution of copper sulfide ore composed mainly of chalcopyrite ( wt %) and bornite ( wt %) using a pretreatment before leaching. The effect of the pretreatment on copper sulfide dissolution was investigated using different types of leaching. Three sets of experimental tests were performed (flask, reactor and minicolumn).MORE INFO
