2019215 · In the flotation tests, potassium dichromate (K 2 Cr 2 O 7), sodium diethyldithiocarbamate (DDTC) and methyl isobutyl carbinol (MIBC) were separately used as the lead depressant, the copper collector and frother.All reagents for tests are analytical grade. Tap water was used for the lab flotation tests. The chemical analysis results of the …

Nine flotation rates were used, for PGMs, chromite and gangue in the roughers, scavengers and cleaning section. The flotation cells were run at different froth depths for this test, as recorded in the published dataset.

Consequently, air is entrained into the plunging jet because of the vacuum effect and generates a large number of tiny bubbles as a result of high shear rate [55].In the downcomer region, the collection of particles on …

We therefore label %Mass Pull as the % of the material (mass) sent to flotation a “pulled/floated” into the concentrate. This number needs to be as small ...

CY-3 is shown one of the outstanding improvements made in cyanidation whereby the coarse metallic minerals are removed from the grinding circuit by means of the Mineral Jig. The hutch product from this jig is amalgamated with a Amalgamator or Clean-Up Pan and thus the coarse mineral values, …

The aggregation behavior of clay minerals is attributed to their complex crystal structure, comprising …
