Abstract
The practical application of manmade geochemical barriers in treatment of waste water in the mining industry is described. The studies of efficiency of natural and modified minerals in reduction of concentrations of heavy metals in mine waste water and in model solutions have positive results. The technical aspects of creation of manmade geochemical barriers are examined, namely, materials, sizes and designs aimed at enhanced efficiency and extended service life of the barriers. The geochemical barriers can be integrated in process flowsheets of operating mines, and are suitable for the independent use in closed mines where the cost of sophisticated waste water treatment systems is too high.
