Latest Patents
Berny Rivera-Vasquez's latest patents include two groundbreaking methods for recovering copper from copper sulfide concentrates. The first patent describes a leaching process for copper concentrates with a carbon catalyst. This method involves adding the concentrate and carbon to an acidic sulfate leach solution, where copper is leached in the presence of an oxygen-containing gas. The process maintains the operating potential above a selected level, ensuring effective copper recovery. The carbon copper sulfide ratio is maintained at a minimum of 1:20, optimizing the leaching process.
The second patent focuses on a leaching process for copper concentrates containing arsenic and antimony compounds. This method utilizes pyrite as a catalyst, with the concentrate and pyrite added to an acidic sulfate leach solution. Similar to the first patent, copper is leached in the presence of an oxygen-containing gas, but under conditions that keep the pyrite substantially unoxidized. The pyrite:copper sulfide ratio is maintained at a minimum of 1:3, ensuring effective leaching while maintaining the integrity of the pyrite.
