On the example of copper-ore enterprises in the Urals we show the level of their impact on the environment and local population. It is determined that the discharges of untreated mine and under dump waters promote high pollution level of heavy metal ions and sulphatescopper is from 190 to 1140 MAC, zinc is from 132 to 3500 MAC, manganese is from 110 to 738 MAC, nickel is from 10 to 12 MAC, cadmium is from 10 to 24 MAC.It is recommended to use electro dialysis method for treating dilute waste water generated in mining industry while developing poor chalcopyrite fields in order to create low-waste resource-saving productions aimed at systematic use of mined ore and recycling of valuable components preventing their loss with liquid and solid production wastes.
