摘要: A heat-transfer model was formulated to determine the distribution of temperature within a bioheap chalcopyrite Sarcheshmeh copper mine. Bioleaching employs mixed mesophilic and thermophilic microbes for Cu extraction. Thermophiles are better than mesophiles dissolve CuFeS2. The solution irrigation aeration rates were taken into account as main operational factors. validated by comparing profiles test columns with those bioheap. used find optimal ratio aeration. It found that when fed at flow rate 5 kg/m2 h air blown 7.5 h, transition from state inside heap possible. In this situation, maximum rise about 332 K (59 °C) after 60 days.
