Calcination

Calcination. Calcinations is the process of subjecting a substance to the action of heat, but without fusion, for the purpose of causing some change in its physical or chemical constitution. The objects of calcination are usually: (1) to drive off water, present as absorbed moisture, as "water of crystallization," or as "water of constitution"; (2) to drive off carbon dioxide, sulphl11 ...

How to Remove Arsenic, Antimony Bismuth from Copper

 · Removal of arsenic, antimony and bismuth from copper may take place in the smelting operations by scorifiion, volatilization, or, under special treatment, by processes of concentration. Owing to the great variety of materials that are treated in economical metallurgy, it is rarely possible to obtain exact weights from any particular operation. It is, consequently, a matter of some ...
