A novel method to improve carboxymethyl cellulose (CMC) performance in talc flotation is described in this paper. Micro-flotation results showed that using CMC as the depressant, strong depression on talc floatability was observed when the pulp pH was adjusted from low (4.0) to high (8.5), which improved the separation performance …

The Mineral talc. Talc is known for being the softest mineral on earth. It is number 1 on the Mohs hardness scale, and can be easily scratched by a fingernail. Talc is not commonly seen in collections, as it is usually uninteresting and fairly common, although a few deeply colored and crystallized examples are known and well sought after.

Talc is found as a metamorphic mineral in veins, in foliated masses, and in certain rocks. It is often associated with serpentine, tremolite, forsterite, and almost always with carbonates (calcite, dolomite, or magnesite) in the lower metamorphic facies. It also occurs as an alteration product, as from tremolite or forsterite.

Abstract. Talc is a naturally occurring magnesium silicate mineral, widely used as a polymer filler. Its main differentiating features in this context are its softness (it is the softest mineral known) and lamellarity (platiness). Useful deposits are widespread and processed by conventional mining operations to produce filler grade material.

(a x ^ { 2 } + b x + c = 0) where (a, b), and (c) are real numbers and (a ≠ 0). A solution to such an equation is a root of the quadratic function defined by (f (x) = ax^{2} + bx + c). Quadratic equations can have two real solutions, one real solution, or no real solution—in which case there will be two complex solutions.
