Trachuk A. Special enrichments of gematit ores of the mine booty Krivoy Rog on the base of radioisotope facilities.

The thesis is devoted to a matter of an actual scientific problem new decision of the enrichment technology development and gematit ores efficient control with the use of low energy gamma-radiation source. The technology chart of lumpy and unit dose Kryvyi Rih deep mining ore-dressing on the basis of radioisotope facilities has been developed differing by application of gamma-radiation low energy source. The increase of iron mass stake was 2,5…12,2% at extraction of iron in the concentrate 75…90%. The selection and realization of rich constituent from lumpy part of iron-ore raw material allows to shorten substantially, or to eliminate expenditures fully on the intermittent split. An actual economic effect from introduction of the iron-ore raw material quality efficient control system and products of enrichment is 39,05 thousand grivna on one device.
