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.

1. EXPLORATION: The gold mining process begins with geologists discovering a deposit. 2. DRILLING: After finding indications of gold, drill rigs are used to obtain samples from below the surface. These samples are analyzed for their gold content. If there is enough gold in the deposit to make mining economically feasible, and after permitting, design and construction, a mine is developed. 3. MINING: .
Jul 03, 2015· It is also usually done in conjunction with a process such as grinding, milling or a gravity separation that increases the surface area of the ore to expose as much gold as possible; this is done because the sodium cyanide solution has no effect on the gold during the extraction process if it does not come into direct contact with the gold particles.
