Abstract
The author offers the calculation procedure for minimum exposure time of ore and mining waste containing polymineral aggregates, as well as for sizes of grains such that limit stresses are only achieved at the grain boundaries. With regard to the calculated mechanical stresses, the ways of increasing recovery of fine valuable components of minerals are identified.
