Abstract

The quantity and trophic diversity of bacteria in flotation samples of sulfide copper-nickel ores in the
concentration plant of Kola Mining and metallurgical company are determined. It was found out that
the bacteria joining the ore and circulating water
flowing from the dump increase their number during the flotation process due to the nutrients joining
flotation reagents, aeration and higher temperature. In summer and autumn periods the number of
microorganisms in samples increases by two-four
orders. Bacteria Pseudomonas sp. dominate in the
process.
