INTRODUCTION Reduction in the quality manganese concentrates adversely affected also another customers, the chemical World reserves of manganese ore are estimated by industry, that produces chemicals and pure manganese 3.46 billion ton that includes 2.54 billion ton in the former compounds for electronics. This led to complication of Soviet Union. Deposits of manganese ore are distributed technologies for producing manganese compounds, to unevenly on the territory of the former USSR. In Ukraine increase in the amount of waste in the form of sludge, is concentrated 82.4% of the total reserves of manganese aggravates the ecological situation. It should be stressed ores, in Georgia 8.9%, in Kazakhstan 2.6%, the share of that it was for environmental reasons
