Hello,
my query has two volleys that may be related.
What are few tips for dealing with high clay copper sulfide ore in flotation. When we get batches of high clay ore, our recovery drops drastically, rougher cells start pulling more than usual. Rougher feed slurry would be very thick despite decent %solids and good grind (as per our target).
My second query is has anyone experienced boiling of rougher cells. Even with all air reduced, the cells would still be boiling. It is even more apparent in the rougher cells further down in the bank. And that leads to very unstable froth bed and rougher cells would be pulling very hard, way more than usual.
