Rational separation of complex copper–zinc concentrates of sulfide ore

Resumo

Monomineral and compound fractions, ore material and concentrates are used to study the 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.
