2016-9-1  The adsorption of cyanide ions (CN −) on pyrite, marcasite and pyrrhotite surfaces was studied using density functional theory.The depressing effects of CN − on these three minerals were then investigated by flotation tests. The calculated results show that the adsorption energy of CN − on the marcasite surface is the largest, −374.91 kJ/mol; followed by pyrrhotite, −364.34 kJ/mol ...
