Prior to compositing the individual downbank rougher and scavenger cell products, for modal analysis, the metal distribution by flotation cell products was determined. It was apparent from this analysis that most of the lead, presumably as liberated galena in the ore, was recovered in the scavenger circuit.

The truth is, that high-grade nickel reserves are being readily depleted, and mining companies are looking for new ways to recover this highly desired base metal. I'd like to dig a little deeper into the recovery of nickel, specifically from low-grade nickel ores, and from bleed solutions from the electrorefining of other metals.

Regardless, carrollite flotation recovery is lower than all other copper sulfides. • Carrollite grain size plays a significant role in the recoverability of cobalt. • Carrollite is best recovered at a narrow size range (20–45 µm), minimal at > 100 µm. • This upper size limit may be increased to some extent with higher collector dosage.

There have been many studies to overcome this problem, and depress talc with various reagents. In this study the flotation of a copper ore in the presence of talc and muscovite was studied. It was found that talc can affect copper flotation mainly via froth phase. The copper grade and recovery were affected in the presence of only 7% talc.
