Electrolytic Refining

2019/12/17Electrolytic refining is a process of refining a metal (mainly copper) by the process of electrolysis. As far as the mechanism of the process is concerned, during electrolysis, a large chunk or slab of impure metal is used as the anode with a thin strip of pure metal at the cathode. Get price

Electrolytic Refining of Gold

The method just described aims at leaving gold in an insoluble state at the anode. Other impurities are usually left there, and the gold sponge, or slimes, needs further refining by methods, to be indicated later. By using a suitable electrolyte the gold can be dissolved from the anode bars and deposited in sheet form on the cathode, while many metals can be left in solution. The active agent Get price

An Introduction to the Electrolysis Process

Copper refining to an almost pure state done by electrolysis is an excellent example of the process. Blister copper is considered to be a highly pure form of copper - around 99%. However, in today's market, this level of purity is still not enough; as a result, the blister copper is purified further using an electrolysis process known as electrolytic refining. Get price

Metallurgic Processes

Electro-refining is used to dissolve an impure metallic anode (typically from a smelting process) and produce a high purity cathode. Fused salt electrolysis is another electrometallurgical process whereby the valuable metal is dissolved into a molten salt, which acts as the electrolyte, and the valuable metal collects on the cathode of the cell.
