Nickel and Cobalt | Solvay
AERO polymeric depressants, such as AERO 7261A, help in making a clean separation by depressing nonvalue sulfide minerals. Solvent Extraction. CYANEX® 272 extractant has proven to be the reagent of choice for the separation of cobalt from nickel from both sulfate and chloride media. It is used to produce a major portion of the world's cobalt.
How to Separate Precious Metal |
A wide variety of different types of electronics and other objects contain at least one type of precious metal. In many cases, the trace amounts of these metals are fused together inside of the object. In order to recover those metals once the object has worn out or broken, you'll need to properly know how to separate the metal.
