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
that is hydrophilic. On the other hand, the rupture of talc crystals along the faces generates non-polar surfaces, which are characterized by a low energy (El-Midany and Ibrahim, 2010 [5]; Mierczynska and Beattie, 2013 [6]). This allows talc to exhibit an inherent hydrophobicity, which is the basis of the separation of talc, by flotation,
Then the second step involves the alteration of serpentine to form talc. The rocks have talc, chlorite, magnesite, sulfides and many different minerals having very low content of quartz in them. In this process, crude ore is grinded and crushed before the refining is done by flotation so that the content of talc …

High quality talc flotation machine used in talc ore beneficiation Talc is hydrothermal alteration minerals. Rich magnesite material by hydrothermal alteration often become talc, so the talc shows olivine and pyroxene, hornblende, dense fire tremolite mineral illusion, etc. Talc is a common silicate minerals, it is very soft and has a soapy feel.
Talc nanoparticles size and time of flotation were found to affect the required amount of collector. Reducing the talc nanoparticles size from 567 nm to 235 nm caused the collector dosage to be significantly decreased from 45 kg t −1 to 2 kg t −1 within 30 min of flotation.
The talc extraction and benefication from carbonatic talcose rocks -talc-magnesite, talc-dolomite and talc-magnesite-dolomite was done using flotation method in case study from Sinec deposit.
Humic acid (HA) has been studied as a potential selective depressant for molybdenite in the flotation separation of molybdenite and talc in this paper.
Talc is widely known for its use in powders and as soapstone. However, most of the talc produced is used as an ingredient in ceramics, paint, paper, roofing, …
minerals found in the ore are talc and chromite. The PGMs are separated from the ore by flotation. In this process unwanted minerals are also recovered. Talc is naturally hydrophobic and its flotation is depressed by polymeric depressants. Chromite is considered ... flotation performance (Shortridge et al. 1999; Dalvie et al.
