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.
Feldspar can be replaced by other minerals and mineral mixtures of similar physical properties. Minerals that could be used to replace feldspar include pyrophyllite, clays, talc, and feldspar-silica (quartz) mixtures. The abundance of feldspar will make these substitutions unnecessary for the foreseeable future. Related topics: Silica.

Talc is a naturally hydrophobic gangue mineral in most sulfide ores. However, talc has vast applications in the cosmetics, paper, and paint industries due to its high chemical stability, and its demand continues to grow. Since flotation is the most effective beneficiation technique for upgrading sulfides, the high hydrophobicity of talc has made its selective separation challenging.
The processing of talc depends on the type of deposit. Commonly, the first step is selective mining, followed by floatation to separate the talc from other minerals (eg, silicates and carbonates such as magnesite). Finally, the higher grades of talc are subjected to highly developed beneficiation processes (eg, fine grinding, air classification).
