Abstract
The analysis of the reduce possibilities of the production and energy costs is carried out from the control view of the material size and the testing characteristics of the technological mineral processing process. Correct sampling results show the distribution of valuable components in the ore, and then the concentration process improves the concentrate quality. A method of selecting massif pieces in order to form a representative sample is considered. There are determined the dependence of the change in the distribution function of intergrowths on the material size and the dependence of the sample mass on the texture and structural ore properties, i.e. the content of valuable material and the content of ore grains in the ore. Studies have shown that with a change in the piece size, there is a change in the limiting values of the magnetite content in them. Improving the concentrate quality depends on the size of the processing products, for the control of which a method is proposed for determining the distribution function by size class in accordance with the lognormal law for finely dispersed materials, regardless of their physical properties.
