Talc
The mined material is pulverized, and the talc is separated from impurities using a floatation process [16]. The fine talc is boiled in dilute hydrochloric acid to remove iron and other soluble impurities. It is then washed with water and dried. The formation of talc from dolomite and quartz has also been reported 1171. 3.

Behavior of talc and mica in copper ore flotation
Talc causes processing problems due to its hydrophobicity which makes this mineral naturally floatable. In addition, as talc is a magnesium silicate mineral, large quantities of talc in flotation concentrates cause problems during smelting, often resulting in the imposition of smelter penalties for mineral processing companies (Beattie et al., 2006).

As a typical gangue mineral in many sulfide deposits, naturally hydrophobic talc needs to be depressed by adding depressants to achieve a good flotation separation. Conventional talc depressants lack selectivity, resulting in the depression of both talc and sulfide minerals. In this study, carrageenan was applied as a selective depressant for talc.
