Regrind Circuits
Regrind mills fine-grind flotation concentrates to liberate locked valuable minerals before cleaner flotation.
Application
Copper, gold, zinc and lead concentrates commonly require regrinding to 20-40 microns for improved liberation and cleaner concentrate grade.
Mill Selection
Stirred mills (Isamill, Vertimill) preferred for fine regrinding. Conventional ball mills used for coarser regrind duties.
