A, qToeBⅢ. Jiu et al., “KOMFI.qeKCHOeltCH0.qb30BaHlleMHHepa..qbltor’0CUpLH” 1990, No. 5 published “for heap leaching ore preparation of new methods.” The article points out that the current research to strengthen the leaching process is more and more urgent. Therefore, the leaching method of the finely ground ore is valued. The method is to pre-treat the finely divided ore with concentrated sulfuric acid and to mature in the heap for several days and nights in order to agglomerate the fine ore (-6.4 mm). The acid-treated coarse ore (+ 6.4mm) is mixed with the fine ore in a conical pile for maturation (the coarse fraction in the pile should be greater than 25%). This paper studies the method of changing ore preparation and improving heap leaching efficiency of carbonate copper mine. It has been shown that by stacking piles of coarse ores (+10 mm) below, the semicircle piles (-10 mm) are sequentially stacked
