MICROWAVE TREATMENT OF ORES

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention refers to ore treatment by means of microwave energy to facilitate the succeeding treatment of ore. Impulses of microwave energy with a duration of less, than 1 second each are used to extract valuable elements, such as metals, out of particles of ore of a basic dimension of 15 and less centimeters. ^ EFFECT: invention facilitates structural change of ore particles without essential change of their mineralogy and composition of ore due to different heat extension of minerals in ore particles under the influence of microwave energy; it also facilitates creation of portions with high stress/tension and microcracking in ore particles. ^ 20 cl, 1 ex
