There is provided a process for the recovery of nickel and cobalt values from a sulfidic flotation concentrate. The process involves forming a slurry of the flotation concentrate in a sulfuric acid solution, and subjecting the slurried flotation concentrate to a chlorine leach at atmospheric pressure followed by an oxidative pressure leach at elevated temperature under acidic conditions.

how is iron hematite concentrated

This concentrate was separated at different magnetic intensities. Magnetite was concentrated at 0.05 T, resulting in a recovery of 23.4% and grade of 95.1 wt%. Ilmenite was at 0.4 T, with a recovery of 55.2% and grade of 84.2 wt%.

Grade Concentrate - an overview | ScienceDirect Topics

ABSTRACT OF THE DISCLOSURE: A process for the extraction of zinc from zinc ferrite residues by pressure leaching with sulphuric acid in an autoclave system is disclosed. The process comprises subjecting a slurry of the zinc ferrite residue to pressure leaching at elevated temperature and low acid concentration under slightly reducing initial conditions followed by pressure leaching at elevated ...

PRODUCTION OF HEMATITE CONCENTRATE FROM LOW …

Jul 01, 2019· Note that the flotation of the hematite-quartz mixture was a reverse flotation, where the drop back and sink were taken as flotation concentrate, so the overall recovery of Fe were determined as: (5) R o = X s + X d. 2.3. Size distribution of aggregates or particles

Two-step flotation recovery of iron concentrate from ...

The typical grade of iron at which a magnetite rock formation becomes economic is roughly 25% Fe, which can generally yield a 33% to 40% recovery of magnetite by weight, to produce a concentrate grading in excess of 64% Fe by weight. The typical magnetite iron ore concentrate has less than 0.1% phosphorus, 3-7% silica and less than 3% aluminum.

Investigation of nanobubble enhanced reverse anionic ...

coarse-grained hematite flotation concentrate index was significantly higher than fine-grained one, indicating that the greater the size of hematite, the better the separation effect. From Figure1B, we know that citric acid has a great influence on the flotation recovery of fine-grained hematite. With
