Аннотация: Numerous studies on introduction of the acidic agglomeration stage into the process of heap leaching of the Republic of Kazakhstan copper ores, were carried out at VNIItsvetmet Institute. The paper summarizes results of the studies carried out on oxidized copper ores from two deposits. In the 1st case introduction of the acidic aggПоказать полностьюlomeration stage was necessary to improve percolation properties of the ore fines (minus 10 mm and finer) in order to achieve higher copper recovery rate. In the 2nd case because of certain material composition of the ore, introduction of the acidic agglomeration stage was necessary to improve leaching of the coarser rocks (minus 40-20 mm) in general, i.e. such parameters as permeability, leaching speed, recovery rate, etc. It was found out that in case of dealing with either highly clayey or fine ores, introduction of the acidic agglomeration operation prior to ore dumping stage is highly reasonable. That would allow both improvement of ore layer permeability as well as intensification of copper ore leaching process in general.
