Metal Recovery Rate How to Interpreted the Mineral

The metal recovery rate, or also known as the mineral recovery percentage, indicates what percentage of valuable metals are expected to be available for sale after the refining process has taken place.The metal recovery rate can be found in a mining company’s National Instrument 43-101 or in a similar applicable international reporting standard.

Definition of Term Recovery rate (mining)

Recovery Rate (mining) is the quantity of metal available for sale post the refining process. For example, if a mining company mentions that it holds a resource of 100 million tonnes of 10 per cent copper with a recovery of 80 per cent, the investors could calculate the sellable amount as 0.10 multiply by 0.80 = 8 per cent of 100 million tonnes

Ore Dilution & Recovery in Mining

Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall. The amount of ore thus left varies considerably

Recovery Rates For Hydraulic And Ground Sluice Mines

Mar 19, 2015· A modern wash plant should have a much higher recovery rate than hydraulic mining if the fancy tech is used like jigs and concentrator bowls for the tiny stuff down to say 200 mesh. If you know the gold in the tails is all within a certain range of particle size, then you only have to engineer your recovery system to catch that range of size

Heap leaching Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the
