An Introduction To The Electrolysis Process

Electrolysis is an integral part of electrometallurgy, and highly pure elements can be produced using this process. Generally, all mining operations require the ore to be beneficiated (treating a raw material to improve its properties). To achieve this, the ore is crushed and roasted to convert sulfides into oxides and finally smelted to.

The slurry that remains after this process has a very fine particle size. Typically, 80 of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to ‘see’ the gold in the leaching process.
