Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts while the impurity remains insoluble. These can then be washed out and processed to give the pure metal; the materials left over are commonly known as tailings.Compared to pyrometallurgy leaching is easier to perform, requires less energy and

• Upgrade (in the case of an existing ball mill circuit) to combi-grinding with high-pressure grinding rolls (HPGR). In this case, the HPGR will be installed before the ball mill and replace the first ball mill chamber, increasing the length of the second chamber. Upsides are good energy efficiency and a high output increase.

The pressure increases about one atmosphere for every 10 meters of water depth. At a depth of 5,000 meters the pressure will be approximately 500 atmospheres or 500 times greater than the pressure at sea level. That''s a lot of pressure. Research equipment must be designed to deal with the enormous pressures encountered in the depths.
