01-01-2020  In the first phase of the present experimental studies, the slags were milled to 75% passing 45 microns, which is the degree of milling done in the existing plant mill-float circuit. A range of commercial flotation reagents that include xanthates, dithiophosphates, mercaptobenzothiazole, thionocarbamates, fatty acids, sulphides and sulphates were used in the flotation test-work.

Enhancing the flotation recovery of copper minerals in ...

Currently, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper. The copper recoveries realized in the plant are much lower than expected and it has been postulated that some copper minerals may be occurring in forms that are more difficult to float like oxides or fine disseminations in the gangue matrix.

reverberatory furnace slag flotation tailings from the Bor Copper Concentrator. The slag was sampled from the crushing line before entering the milling section of the concentrator, whereas the slag flotation tailings were sampled from the tailings disposal line. The slag sample was ground to pass through a 75 µm sieve. The tailings

The Recovery of Copper from Smelting Slag by Flotation ...

08-02-2017  Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and XRD.

THE ESTIMATION OF SLAG PROPERTIES

Slag/metal reactions are very important in the production of clean metals (eg. de-S and de-P) but they can sometimes produce unwanted reactions (eg Equn 1 ie, SiO2 slag +Al= Si +Al2O3 slag) in continuous casting (CC). For steels containing >1% Al this

Mineral processing - Wikipedia

There are a number of cells able to be used for the flotation of minerals. these include flotation columns and mechanical flotation cells. The flotation columns are used for finer minerals and typically have a higher grade and lower recovery of minerals than mechanical flotation cells. The cells in use at the moment can exceed 300 m 3.
