Interaction of technological solutions from underground leaching and cenoman horizon ores

In leaching field decommissioning, both artificial and natural methods of environment regeneration are used. The former include rinsing with ground water or with suitable chemicals, the latter are based on geochemical interactions of ores. Simple experiments were conducted aimed at monitoring the natural ore ability to slow down the motion of ecologically important ions NH4+ and NO3-. Seven ore samples were used occurring in the leaching field for experiments in a glass flow column. An actual solution, i.e., the sorption waste from the chemical plant was used as the liquid phase. Studied were ore permeability, capacity for capture of ecologically important ions (in an order of 102 g/t for siltstone, 100-101 g/t for sandstone), neutralizing capacity.
