Data Support in the Choice of Mine Water Treatment Technology


Mathematical modeling is used in this work in the analysis of options for the implementation of acid mine water treatment technology. Ta technological scheme of metal-bearing mine water treatment is proposed and includes two stages. The first stage, the treatment of mine water to the required degree to extract solid insoluble sediment for further processing, is implemented in a mobile technological complex installed in places of mine water outpouring. Selective extraction of individual metal powders is delivered in a stationary complex in applying the centrifugal conversion method using plasmatron. In the first step, the metal ions contained in the mine water should be complete recovered with maximum energy-saving. The condition for complete extraction of useful components from mine waters is pH values corresponding to the beginning of precipitation of hydroxides of various metals and complete precipitation, which depend on the nature of metals, their concentration in solution, temperature, impurity content. The process regime must be manageable to ensure its adequacy in the quality of raw materials under conditions of changing mine water flow rates and concentrations of ingredients. The technological mode must be manageable to ensure its adequacy in the raw material quality under changing mine water discharges and concentrations of ingredients.
