Talc Ore Overview

Talc | Imerys

Talc is a hydrated magnesium silicate. There are many types of talc and each ore body has its own features, its own geology, 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.

What is Talc? - Industrial Minerals Association - North ...

Talc ores also differ according to their mineralogical composition (i.e. the type and proportion of associated minerals present). They can be divided into two main types of deposits: talc-chlorite and talc-carbonate. Talc-chlorite ore bodies consist mainly of talc (sometimes 100%) and chlorite, which is hydrated magnesium and aluminium silicate.

Talc - an overview | ScienceDirect Topics

Talc has low hardness of 1 in Mohs scale and can be scratched by finger nail. This mineral is an essential ingredient of talc schists and chlorite schists (Table 7.1). Talc is a metamorphic mineral resulted from the metamorphism of magnesian minerals, such as serpentine, pyroxene, amphibole, olivine, in the presence of carbon dioxide and water.

THE FLOTATION OF HIGH TALC-CONTAINING ORE

2014-12-10 · 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 ...
