Ore processing – Waihi Gold

Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself.

Batu Hijau mine - Wikipedia

Ore from the mine has an average copper grade of 0.49% and an average gold grade of 0.39g/t. Crushed ore is further reduced in size by Semi-Autogenous Grinding and ball mills. Once milled it is sent through a flotation circuit which produces a concentrate with a grade of 32% copper and 19.9g/t gold. The mill

Canada’s four newest gold mines - Canadian Mining ...

The high grade nature of the ore has led to one challenge in the mill: When the rock hits the SAG and ball mills, coarse visible gold is freed. The mills act as big centrifuges, forcing heavy gold particles to the outside, where they work their way into nooks and crannies. In an August press release, the company revealed that a 4.7-kg grab sample taken from gravity recoverable gold trapped behind a SAG mill liner graded 23,547 g/t gold.

Gold processing 101 - Mining Magazine

An ore containing 1% sulphur will produce a mass pull of approximately 5% by weight to a bulk flotation concentrate where recovery is the key driver. If this ore also contains 1g/t Au (for GSR =1), and 90% recovery to concentrate is achieved, then 0.90g will be recovered and with a concentration ratio of 20 (5% to concentrate) this corresponds to 18g/t Au in concentrate.

Tailings - Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock
