Talc is a magnesium silicate clay mineral and when present in molybdenite concentrate, contributes to the acid-insoluble content. Talc has a laminar structure as shown in Fig. 4.As can be seen, talc is a tri-layered hydrated magnesium silicate with a chemical formula of 3MgO·4SiO 2 ·H 2 O or Mg 3 (Si 2 O 5) 2 (OH) 2 (Xu et al., 2018, …
The Cl − ions weakened the adsorption of LS anions on the Ca 2+-modified talc surface, and the adsorption affinity of Na + ion toward the Si-O layers was much weaker than that of Ca 2+ ion. Thus, CLS exhibited the strongest depression against talc's floatability, followed by CaCl 2 + SLS (sodium lignosulphonate), and then SLS. SIBX ...
In broader terms, mineral processing consists of two functions. Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with concentration.

Introduction. Talc is an industrial mineral, which is composed of hydrated magnesium sheet-silicates with a theoretical formula of Mg 3 Si 4 O 10 (OH) 2 that belongs to the phyllosilicate family (Yehia and AL-Wakeeel, 2000, Fuerstenau and Huang, 2003, Ozkan, 2003, Boghdady et al., 2005). It consists of a two dimensional sheet structure …
talc, common silicate mineral that is distinguished from almost all other minerals by its extreme softness (it has the lowest rating [1] on the Mohs scale of hardness). Its soapy or greasy feel accounts for the name soapstone given to compact aggregates of talc and other rock-forming minerals. Dense aggregates of high-purity talc are called steatite. ...
