Abstract
Monomineral and compound fractions, ore material and concentrates are used to study effect of basic processing factors on mineral separation. The key criteria are determined to choose a method of selective extraction of minerals and their species in various cycles of a process flow chart. Such key criteria include: degree of activating effect of copper minerals on other sulfides; multifunction role of iron compounds; medium pH values; combination and concentration of depressing ions of modifying reagents; ratios of selective collectors in their combinations; scientific principles of flow chart designing; principles of concentration and recovery of minerals in different processes of dressing.
