Single center experience on talc poudrage morbidity: focus on high talc dosage

open access: yesJournal of Cardiothoracic Surgery, 2011
Malignant pleural effusion (MPE) is a common clinical problem of concern for most of the pneumologists and thoracic surgeons. A general consensus regarding the use of talc poudrage in treatment of MPE exists, but only few studies analyzed in detail talc ...

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.

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.

Surface pre-coating of talc particles by carboxyl methyl cellulose adsorption : study of adsorption and consequences on surface properties and settling rate [PDF]

open access: yes, 2006
This paper investigates the adsorption of different sized carboxyl methyl cellulose (CMC) onto talc particles (adsorption isotherm, adsorption reversibility), its consequences on the particles properties (electrophoretic mobility and surface wetting) and

Two-dimensional talc as a van der Waals material for solid lubrication at the nanoscale

open access: yesNanotechnology, 2021
Talc is a van der Waals and naturally abundant mineral with the chemical formula Mg3Si4O10(OH)2. Two-dimensional (2D) talc could be an alternative to hBN as van der Waals dielectric in 2D heterostructures.
