Aug 21, 2020 The high acidity of the solution is favorable to the adsorption of gold by activated carbon, so low pH value will increase the capacity of gold adsorption by activated carbon. However, for cyanide medium, pH is not allowed to be too low, so the pH value of heap leaching-adsorption process should be maintained at 911. 3.
The heap leaching cyanidation method is that gold-containing low-grade ore is crushed or agglomerated into a lump of 3-10 mm, stacked on an impermeable bottom pad, and sprayed from the top of the heap with a cyanide solution to dissolve the gold in the ore The gold-bearing precious liquid percolates out of the mine heap and pools into the precious liquid pool.
