Effect of pH on Copper Cleaner Flotation (after Regrind ...

Mar 17, 2017  Accordingly, higher pH levels were adopted for cleaner flotation to enhance selective flotation of copper VS pyrite. Concentrate regrinding to a product size of 80% passing 30 µm is adequate to yield, after three stages of cleaning at pH 11-12, a final concentrate assaying 31% copper.

A STUDY OF CLEANER FLOTATION IN AITIK

Aitik mine is a large scale low copper grade mine in northern Sweden. Recently it was expanded and a new concentrator was built. Milled tonnages in 2014 were 39 Mton. Main economical mineral of interest is chalcopyrite and it is recovered via flotation. The flotation process is a rougher-scavenger-cleaner process where cleaners are used to
