What are froth floatation chemicals and How to Buy froth floatation
The 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.
