    Talc Ore Using Statistical Analysis and Response Surface

    Talc ore from a local supplier in Slovakia (Gemerska Poloma) was used. The main gangue mineral groups in the ore sample were silicate minerals (laminated phyllites with various chemical composition), oxide (quartz), carbonates (mainly dolomite), and sulfide minerals (mainly pyrite). Individual samples were crushed in a crucible and analyzed. The results of the chemical analysis are

Mineralogical and Geochemical Characterization of Talc

The detailed mineralogical, physical and chemical characterization of nine samples of imported cosmetic talc and of two samples of talc from currently non-productive Mexican ore deposits (Oaxaca and Puebla States) is presented. The imported cosmetic talc was classified into two groups, considering whether they are packed in the country of origin or in Mexico and considering their price. X-ray

Talc an overview ScienceDirect Topics

Talc –pyrophyllite group comprises small sheets of soft white phyllosilicates that are greasy on touch. Talc and pyrophyllite cannot make mixed crystals because of large differences in ionic radii of magnesium and aluminum. Talc [Mg 3 (OH) 2 Si 4 O 10] crystallizes in monoclinic and triclinic system. It most often occurs as foliated to fibrous masses. Talc has low hardness of 1 in Mohs scale and can be scratched

Talc is a clay mineral, composed of hydrated magnesium silicate with the chemical formula Mg3Si4O10(OH)2. Talc in powdered form, often combined with corn 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 fibrous masses, and in an exceptionally rare crystal form. It has a perfect basal cleavageand an uneven flat fracture, and it is foliate

1/1/1989· Talc is determined by infrared spectrometry in talc ore and mineral mixtures containing clinochlore chlorite, dolomite and magnesite as major minerals. When the Si-O-Si vibration at 668 cm −1 is used, the calibration graph is linear up to about 0.5 mg of talc. Band overlap from chlorite is corrected by using the ratio of absorbances at 668 and 3620 cm −1. Talc (⪢15%) in talc/carbonate

Talcum powder is made from talc, the softest mineral on earth. Talc deposits are often located near asbestos ore since the two minerals are chemically similar. This triggered fears in the 1960s that mined talc could be contaminated with asbestos and cause cancer. Home talc products have been asbestos-free since the 1970s but the debate continues today.
