Justification for Criteria for Evaluating Activation and Destruction Processes of Complex Ores

The mining industry is faced with the problem of depletion reserves easily beneficiated minerals containing valuable metals. characteristic features ores involved in processing are fine dissemination; low content components; and similar physical, chemical, surface, technological properties minerals, among others. Under such conditions, increasing efficiency mineral becomes primary importance. Creating highly efficient, environmentally safe technologies on basis deep study material, mineralogical composition, as well using developing methods techniques for testing materials at successive stages raw material transformation, enable to solve problems. Criteria assessing flow processes presented article. A complex criterion substantiated proposed quantitative assessment degree physical energy impact ore preparation flotation enrichment materials. calculated activation data by differential integral kinetic methods. In addition, an empirical indicator was introduced into criterion, which allows accuracy criterion. This not only estimate influence from position averaged estimation full interval degrees transformation 0 1, but also gives possibility consider required number transformation; example, if it necessary make estimations narrow temperature intervals. calculation parameters obtained carried out before after application physical–energetic thermal analysis.
