gold cil carbon in leach process is an efficient design of extracting and recovering gold from its ore. by cyaniding and carbon leaching crushed gold ore slurry simultaneously, cil process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%. get price
sphalerite, a zinc sulfide ore is considered as the main and primary source to produce zinc metal. oxidative leaching is one of the major processes applied for the zinc recovery from sphalerite and many researchers have investigated its kinetic analyses 2-8 . extensive investigations have been carried out on the
subjected to, 1 conventional agitation leach, 2 pressure leach, 3 electric arc furnace dust pretreatment in microwave oven, and 4 leaching with ultra sonic agitation. based on the information gathered, they concluded that the conventional agitated leaching method was the most effective since it displayed the highest zinc recovery of 74%.
