Talc is a hydrous magnesium silicate mineral with the chemical formula Mg 3Si 4O 10(OH) 2. It is the softest known mineral with the hardness of 1 on Mohs scale and has density of 2.78 (Anthony et al.2001). Natural floatability of talc is closely related to its three-layer sheet crystal structure. Positive charge of magnesium layer is ...

Before flotation process the ore goes through primary grinding in ball mill to obtain milled ore, impurities are removed in a cascade of flotation cells. Talc concentrate slurry is thickened in settling tanks (slurry) before drying. The concentrate Talc is dried by pressure filters. The resulting filter cake is an intermediate product.

Feb 11, 2021Ore Flotation (Dense Medium Separation) For the flotation experiments, 10.0 g of the pulverized talc ore (feed) was added to 200 mL of 1% PEG-6000 frother in a 500-mL laboratory bottom driven batch flotation cell. The mixture was well-shaken, allowed to equilibrate, and separated after 5 min.

Talc for paper and board. This hydrophobic mineral has many functional applications. It can be used to reduce pitch related deposits during pulp, paper and board production and improve machine runnability. The combined hydrophobicity and platy nature of the mineral can also impart speciality functionality when used as a filler or coating pigment.

When there is no inhibitor, the talc has good floatability, and the flotation recovery rate reaches 84%. In the system where the flotation agent and the inhibitor coexist, the floatability of the talc is strongly inhibited. When the amount of guar gum is 50 mg l −1, talc is almost completely inhibited.
