Description. The term talc refers both to the pure mineral and a wide variety of soft, talc-containing rocks that are mined and utilized for a variety of applications. Talc forms mica-like flakes. Talc is the softest mineral on the Mohs hardness scale at 1 and can be easily cut and crushed. Talc has perfect cleavage in one direction.
Talc ore contains about 76% talc, 13% chlorite, 9% dolomite and 1.5% quartz. Table 1 shows the chemical analysis of talc ore. It contains about 47% SiO 2, 28% MgO, 6%CaO and 1% Fe 2O 3. Thus, the talc ore is considered as low grade and it was necessary to increase its grade to be suitable for different industrial applications. 3.2. Crushing of ...

Talc is usually green, white, gray, brown, or colorless. It is a translucent mineral with a pearly luster. It is the softest known mineral and is assigned a hardness of 1 on the Mohs Hardness Scale. Talc is a monoclinic mineral with a sheet structure similar to the micas. Talc has perfect cleavage that follows planes between the weakly bonded ...
Colorless, transparent or white, but light green, light yellow, light brown or even light red due to a small amount of impurities; The cleavage surface is pearl luster. Hardness 1, specific gravity 2.7 ~ 2.8. Talc ore powder is usually divided into several grades, and stainless steel vibrating screen is usually used for classification.
What is Talc? Talc is the world's softest mineral, a hydrated magnesium silicate. Talc as an ore body has its own features, geology and was formed many millions of years ago. As a natural ore, talc is always found in combination with at least one other mineral. The most common of these is chlorite, a chemically and structurally similar ore.

The use of black talc ore. There are five kinds of industrial talc according to color: Pink talc, white talc, green talc, grey talc and black talc. The reason why talc has different colors mainly depends on the color of the minerals associated with talc. When it contains a certain amount of organic matter, the talc is black to gray.
Talc's lamellar platelets make paint easier to apply and improve cracking resistance and sagging. They also enhance matting. In anti-corrosion primers, talc is used to improve corrosion resistance and paint adhesion. Talc also brings benefits to inks, jointing compounds, putties and adhesives.

The talc chlorite was improved to 82% by attrition in the presence of sodium hexametaphosphate at a pulp density of 76% [3]. Beneficiation of talc-carbonate ore using polypropylene glycol as a frother was studied to increase the rate of talc flotation [4]. A clean concentrate analyzing 93.5 % talc was obtained at a recovery
The in situ ore comprises 60–85% talc and 5–30% albite, with brown iron oxide impurity above the watertable and pyrite below. Laboratory testing during the late 1970s showed the talc–albite mixture to be suitable for refractory and ceramic uses. Recorded production totals ~180 000 t, mostly of second and third grade talc.

ore, the ore was ground to minus 0.95 cm, tertia ry crushing, grinding of coarse product by using a pebble mill in a closed circuit with Raymond mill, and finally grinding of the fine product with fluid energy mill. Concentrating tables were installed to remove high gravity product containing Ni, Co and iron minerals.
The ore is mineralogically similar to that of Merensky reef in South Africa, but differs in that it contains high concentrations of talc. The lower recovery (of typically around 79%) is partly a result of the high concentrations of talc. Talc is naturally hydrophobic and therefore tends to float and report to the concentrate. During the ...
