In the last decade uncertainty anthropogenic environmental load higher topic theoretic substantiation and technology and installation for heavy metals extraction of anthropogenic water (hydromineral resources) development it is getting privileged among fundamental and reconnaissance research in “Ore concentration”.

Probably, that when ore mining not only ore extraction and geosystem transformation take place, but also social geosystem transformation in tote and structure part it to have been anthropogenic water. That anthropogenic water should have natural area correspond and society will be a number principles implement, including the principle of optimal correspondence use for society and natural area necessity and principle of compensation of the natural withdrawals. Therefore is very important anthropogenic water for hydra mineral deposit labeling on the grounds of adequate resources estimation.

An effective treatment of hydra mineral resources can be carried out under three conditions:

• flow anthropogenic water purposeful forming in concordance with quantitative- qualitative variables and possibility complementary product in order to receive;
• selective methods valuable components extraction of waste treatment adaptation on the ground applicability bounds definition and methods combining;
• mobile flowchart of treatment use, that is give an opportunity complementary needed product.

Instrument rating for competitive choose of optimal extraction technology of heavy metals from hydra mineral resources can be technology classification, which combine qualitative of waste, physical-chemical valuable components and possibility treatment. We are developed this classification for cooper anthropogenic water from enterprise cooper sector. Because of classification valuable we are used integral indicators of anthropogenic cooper hydra mineral resources qualitative (IQ), which include: content of cooper, active reaction (pH) and index cooper.

In the process of cooper-zinc ore mining and treatment fair quantity anthropogenic water be generated, 2 – 7 m³ on the ton of ore. On the all stages of technological process water formed, can be neutral, acid and alkaline solution, thin or intense mineralized, with fair quantity variation of components content. Every day with waste by enterprise cooper sector loosed 23,1 thousand tons of cooper, about 50 thousand tons of zinc and tens of tons another metals.

On the water heavy metal containing apply to acid sulfate shaft and under dumping water. The dump on the enterprise cooper sector from South Urals region occupy more 1800 hectare, this is caused fair quantity volume of under dumping water. Cooper and zinc concentration in the this waters exceeded maximum permissible concentration and reached 600 mg/dm³ for the cooper and 1100 mg/dm³ for the zinc. Analysis and accounts showed, that basic form of cooper and zinc migration (64 – 97%) in this water is dissolve form. This is optimal form for selective metal extraction. Realization of effective treatment hydra mineral resources is possibly on basis of complex adapted for valuable components extraction methods of sewage treatment : galvanic coagulation sorption and sedimentation.
