STUDYING ORE PREPARATION PROCESS FOR EXTRACTING VALUABLE COMPONETS
The problem considered in the work relates to the field of metallurgy. The authors studied the chemical composition of ore interlayers with the help of electronic probe micro-analysis, there has been made a scientific review of the work and suggested recommendations to improve the processes of ore-preparing for hard-cleaning raw rare and rare-earth metals. The scientific novelty of the work consists in solving a private scientific problem that will permit to avoid un justified power, time and labor costs for carrying out both the stage of ore-preparing itself and the following stages of consecutive extracting metals, as well as to give at the output the optimal size of mechanically or physically prepared material that permits to ensure the necessary area of minerals interaction with reagents at the following stages of ore treatment and to reduce the time of mass transfer to the interaction boundary.
