Description
Gulnara Katkeeva and seven colleagues published a mining study in two thousand twenty-six on coaxing copper from a stubborn ore mineral. Chrysocolla, an oxidised copper mineral, floats poorly because its surface reacts weakly. A sulphur coating step normally helps, but results stay poor.
The team pre-treated the ore with alternating current before the coating step. Current turned the surface into a copper oxide that then converts readily into a float-friendly sulphide. Tuning current, time, acidity, and reagent dose gave a best recipe. On natural ore, copper recovery leapt from about twenty-nine percent to about eighty percent. The concentrate grade doubled as well. The authors offer the method for hard oxidised copper ores.
