Insights into the adsorption performance and mechanism of hydrated Ca ion on talc (001) basal surface from DFT calculation

open access: yesInternational Journal of Mining Science and Technology, 2022
The utilization of Ca ion as assistant depressant of CMC on talc has been widely reported. Thus, the study on the adsorption mechanism of Ca ion on talc surface is very crucial for understanding the performance of CMC on talc depression.

Flotation Separation of Chalcopyrite and Talc Using Calcium Ions and Calcium Lignosulfonate as a Combined Depressant

open access: yesMetals, 2021
As a major gangue mineral in sulfide ores, talc is difficult to separate from chalcopyrite in the flotation process due to its natural floatability, which affects the subsequent smelting process.

Frictional behavior of talc-calcite mixtures [PDF]

open access: yes, 2015
Faults involving phyllosilicates appear weak when compared to the laboratory-derived strength of most crustal rocks. Among phyllosilicates, talc, with very low friction, is one of the weakest minerals involved in various tectonic settings.
