Distillation process for separating silver and copper

U.S. Pat. Nos. 3,998,926 and 4,086,084 teach the removal of silver and base metals from platinum group metal concentrates by heating the concentrates in the presence of a halogen at a temperature of greater than 900° C. in order to halogenate the silver and base metals present, allowing for their removal from the platinum group metals.

Cobalt

Cobalt is concentrated in lithophorite ((Al, Li)Mn4+O2(OH)). Chemical analyses of initial concentrates gave values of 25 percent manganese and 0.17 percent cobalt. Magnetic separation yielded concentrates with up to 41 percent manganese and 0.22 percent cobalt with recoveries of 95 and 93 percent, respectively.

Voltaic Cells | Introduction to Chemistry

The cells are constructed in separate beakers. The metal electrodes are immersed in electrolyte solutions. Each half-cell is connected by a salt bridge, which allows for the free transport of ionic species between the two cells. When the circuit is complete, the current flows and the cell “produces” electrical energy.
