Talc separation from talc-carbonate ore to be suitable for different industrial applications

Depression mechanism of the zinc sulfate and sodium carbonate combined inhibitor on talc

“…Due to its natural hydrophobicity, talc is easily mixed http://dx.doi.org/10.1016/j.colsurfa.2016.04.057 0927-7757/© 2016 Elsevier B.V. All rights reserved. into flotation concentrates thus reducing concentrate grades [1]. In addition, because talc is a magnesium silicate mineral, large quantities of talc in metal mineral concentrates might cause problems during smelting, often resulting in the imposition of smelter penalties for mineral processing companies.…”

The Art of Talc Flotation for Different Industrial Applications

“…It is recognized that the crystalline structure is one of the main factors that determines the wettability of layered silicate minerals such as talc. Talc is a hydrous magnesium silicate, Mg 3 Si 4 O 10 (OH) 2 , which is related to the sheet structure of the phyllosilicate (Yehia and Al Wakeel, 2000 [1]). However, natural floatability of talc is closely related to its three-layer sheet crystal structure (Fuerstenau et al, 2003 [2] and Fuerstenau et al, 2007 [3]).…”

“…Besides, the solution pH affects the talc floatability. In acidic and alkaline solution, water molecules would hydrate the negatively charged sites (SiO − ) on the edges and hence, the talc surface would be more hydrophilic (Yehia and Al Wakeel, 2000 [1]). At neutral pH, talc surface has a weak affinity for water molecules and air bubbles readily displace any weakly adsorbed water on the uncharged surface.…”

Dynamic contact angles on PTFE surface by aqueous surfactant solution in the absence and presence of electrolytes

“…The wetting properties of solid materials are of both fundamental and practical importance due to their wide range of applications such as detergency [1], liquid surface coating [2][3][4], flotation [5,6], chemical reactions at solid-liquid interface [7], agrochemicals, flows in reservoirs [8][9][10][11], and mass transfer in packed column [12]. Understanding and characterizing the wettability of solid surfaces are thus highly essential.…”
