THE FLOTATION OF HIGH TALC-CONTAINING ORE FROM THE

flotation of talc prior to flotation of PGMs was tested to compare the two methods and the process flowsheet for this is shown in Figure 5.6. 1.2. PROBLEM STATEMENT There are two problems identified at the Mimosa Mine. They are: (i) Low PGE recoveries (79% compared to the South African Merensky operation’s recoveries of between 80% and 95% (Cramer, 2001)).

2020-10-20  For mixed minerals flotation, the mass ratio was 1:1 (1 g chalcopyrite and 1 g talc) and the Cu grade was 16.9 %. The mixed minerals flotation were also carried out in a 40 mL XFG flotation machine, and the conditioned process was the same as the single mineral flotation. The concentrates and tailings were analyzed for Cu grade.

Column flotation of talc - ScienceDirect

1989-09-01  Flotation of low grade talc was carried out in a laboratory flotation column with fine air bubbles. Recovery of talc was approximately 83% with a mean residence of 73 s and a whiteness of 84, which was significantly higher than that of a conventional agitation-type flotation cell. A mathematical model was developed to predict the recovery of talc, based on the rate

Talc - Wikipedia

Talc is a clay mineral, composed of hydrated magnesium silicate with the chemical formula Mg 3 Si 4 O 10 (OH) 2.Talc in powdered form, often combined with Gypsum starch, is used as baby powder.This mineral is used as a thickening agent and lubricant; is an ingredient in ceramics, paint, and roofing material; and is a main ingredient in many cosmetics. It occurs as foliated to

Effect of Ultrasonication on the Flotation of Talc ...

2004-06-17  The natural hydrophobicity of talc was depressed by the use of ultrasonic treatment during flotation. The recovery of the talc decreased by nearly 30% after 4 min of ultrasonic preconditioning. In addition, two talc depressants, namely, IMP4 and carboxymethyl cellulose (CMC), were compared during ultrasound treatment. The guar gum IMP4 showed a better
