Abstract

Mine and pit waters are formed as a result of falling of underground and surface natural waters into mine workings, with their following contamination. Finedispersed suspended particles, metal ions and oil products fall into water during the mineral extraction works. A complete factorial experiment was set for assessment of influence of various technological factors on results of flotation of oil products and other contaminants from mine water. Obtained equation has shown that rotation rate of mechanical flotation machine impeller, directly connected with the grade of air dispergation in formed pulp-air mixture, makes the biggest influence at the stage of flotation purification of mine water. Taking into account the research results, pneumatic columnar flotation machines are the most useful equipment for flotation purification of pit water from oil products. The key working principle of these machines is preparation of pulp to flotation, at the expense of its saturation by fine-dispersed air bubbles in ejecting units. Process flowsheet of mine water purification, developed by the results of experimental-industrial tests, included preliminary clarification of waste water, basic and recleaner flotation in columnar flotation machine, and filtration of flotation tail of columnar flotation machine through the sorbent layer (activated carbon). As a result, there was obtained the water, purified with required quality.

Authors express their gratitude to A. V. Bobrikov; laboratory team and its Head - N. V. Boteeva; and team of mine and pit waters , purification site of JSC “Safyanovskaya med” for the help in this work.
