This is based on an average analysis of the ore samples taken from different parts of the heap body. The total copper recovery was found around 60% while the average chalcopyrite leaching recovery was 32.6%.

However, almost 97.5 % of the total water belongs to seawater or saline water, and only around 2.5% is freshwater that’s essential necessities for the human survival and industrial promotions (Postel et al., 1996).Much of freshwater was stored as the solid …
view moreThe method of heap leaching is a low-cost technique that can often achieve high recoveries from oxide ores, typically greater than 70% depending upon the kinetics of reaction. However, the world copper resources are mainly chalcopyrite, and achieving high recovery from these copper sulphide deposits has been challenging due to the complexity of ...

This size will typically be from ¾ inch to 3/8-inch top size. The crushed ore is then bedded in a vat with special care to prevent segregation of the coarse and fine fractions.
