Conventional beneficiation of the Platinum Group of Metals (PGMs) relies on the use of inorganic chemicals. With the depreciation of high grade deposits, these conventional processes are becoming less economically viable. Furthermore, the use of chemicals has serious negative impacts on the environment. To address the challenges of conventional PGM beneficiation, biobeneficiation has been ...

Jan 6, 2022The froth floatation process involves the use of many chemicals. There are chemicals known as collectors whose function is essentially to trap ores. The collectors are mostly anionic sulfur ligands and Xanthate salts. There is also another group of chemicals called Frothers. They are responsible for stabilizing the in the floating process.
