The gold mining process involves crushing the ore into sand and dust to liberate and recover the gold. What's leftover is called tailings. Ballarat Gold Mine uses its robust management and monitoring processes to make sure its produced gold tailings comply with all license conditions and permits necessary for the safe storage of tailings.
Copper is obtained by smelting suitable ores and is most commonly used in the form of alloys; that is, other pure metals are added to produce new metals with different properties. Sources of copper ore Copper ores are found in only a parts of the British Isles. Evidence for the early sources of copper ores is somewhat patchy.

Treatments of ores to concentrate their valuable constituents (minerals) into products (concentrate) of smaller bulk, and simultaneously to collect the worthless material (gangue) into discardable waste (tailing), are called as ore dressing/ mineral processing methods. This module explains the methods adopted in mineral processing. Read less
Methods of Mining Copper Ore. There are two main methods for extracting copper ore: open-pit mining and underground mining. Each method is chosen based on the depth and …
Assessment of the ore's suitability for preconcentration technology is the first step in harnessing these potential savings. This paper discusses how coarse ore sorting and gravity separation could be employed underground in a narrow-vein scenario and details the test work that is required at
