We show that sulfatecontaining minerals of mining raw materials and waste play a role in the formation of wastewater composition and chemical contamination of soils The backgroundforming elements Fe and Mn were found to determine the nature of the distribution of soluble forms of Cu Pb Zn and Co in the soil profile while the content of aggressive fractions of humic acids intensifies their migration activity

During normal weathering of these mineral deposits acid is produced but at a very slow rate so slow that natural neutralisation processes readily remove the acidity However during mining and mineral extraction the rock mass is extensively fragmented thereby dramatically increasing the surface area and consequently the rate of acid production
