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
Talc definition is a very soft mineral that is a basic silicate of magnesium, has a soapy feel, and is used especially in making talcum powder
Talc talc is the softest mineral, demonstrated by its position at the bottom of mohs scale of hardness with a relative hardness value of it has a soapy, greasy feel talc is formed by the hydrothermal alteration of ultrabasic rocks, or low grade thermal metamorphism of siliceous dolomites

The most defining characteristics of talc are color and texture talcs color can range between white, gray, or a pale green hue loomis, , and it leaves a white streak on any surface it comes in contact with the distinctive greasy and chalky quality of it allows it to be identified as the mineral talc before further examination is
Talc is a common mineral in some metamorphic rocks it is a sheet silicate which means that it is structurally similar to micas and clay minerals this mineral is always an alteration product, it forms at the expense of other preexisting minerals
Dec , talc is a mineral in clay mined from underground deposits its the softest mineral known to man and that makes it useful in a wide range of consumer and industrial products
Talc ores also differ according to their mineralogical composition iE the type and proportion of associated minerals present they can be divided into two main types of deposits talcchlorite and talccarbonate talcchlorite ore bodies consist mainly of talc sometimes and chlorite, which is hydrated magnesium and aluminium silicate
The mineral talc is a hydrous magnesium silicate a massive talcose rock is called steatite, and an impure massive variety is known as soapstone talc is used commercially because of its fragrance retention, luster, purity, softness, and whiteness other commercially important properties of talc are its chemical inertness, high dielectric strength, high thermal

Like the neutral clay minerals, natural pyrophyllite and talc have no need for counterions and consequently contain no interlayer species the basal surfaces of the clay minerals are entirely composed of quotsiloxanequot oxygens that coordinate tetrahedral cations
Because talc is a naturally occurring mineral that is mined from the earth, there have been recurring questions about its safety and whether talc contains harmful contaminants, such as asbestos asbestos is also a naturally occurring silicate mineral, but with a different crystalline structure
