FIELD: technological processes.
SUBSTANCE: method for crushing of mineral raw materials includes supply of crushed material of at least one surface-active substance in mill and wet crushing. Surface-active substances used are fluoridised monatomic spirits of limit row with common formula H-(CF2CF2)n-CH2-OH, where n=1÷5, in amount of 25÷100 g per ton of crushed material.
EFFECT: higher efficiency of enrichment process due to higher selectivity of useful component opening, improved extraction and better quality of concentrate in further enrichment.
