اقرأ أكثرLiu et al. (2012) investigated the leaching kinetics of copper from low-grade copper ore containing calcium-magnesium carbonate in an ammoniacal leaching medium. When leaching carbonaceous ore, an ammoniacal leaching medium is occasionally preferred over an acid medium because it does not react with carbonates and siliceous gangue in the ore.
اقرأ أكثرCopper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace.
