Gold processing 101
At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost

A delay in the delivery of the primary ball mill, caused by the unexpected cancellation of the original order, has been overcome by procurement from an alternative source, with the new ball mill now en route. Over the past six months, unusual supply chain conditions have made it difficult to provide precise and accurate operational timelines.

When the particle size of gold in the ore is 1 ~ 0.42mm, the recovery was 82%, and when the particle size is 0. 42 ~ 0.2 mm, the recovery rate is only 60. 5 %. There is a contradiction between the feeding concentration of the clay trough on the gold mining ship and the washing effect of the cylinder trommel screen.

GRAVITY CONCENTRATION OF GOLD FROM CYCLONE FEED IN GRINDING
Gold was subjected to the gravity concentration device in its coarsest state, i.e., as soon as a particle was discharged from the mill it saw the gravity concentration device. There were also some disadvantages: The gravity circuit had to process 3 or 4 times the new feed rate to the mill (the entire circulating load).

Ball Mills
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rod mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

Free gold can also accumulate in the mill, either in the liners (at the Echo Bay Lupin operation when they took out the steel liners during a liner change they would put them in a secure area and grind off the surface to recover a lot of gold), or behind the liners (just ask any mill mechanic that does liner changes).
