Influence of dry grinding on talc and kaolinite morphology: inhibition
The effects of dry grinding in a porcelain ball mill and a chrome steel ring mill on the structure and morphology of talc and kaolinite minerals and mixtures have been studied. It is well known that ground talc is easier to make down as a suspension than unground talc and that it displays better rheological behaviour in the slurry.

A Brief Review of Poly(Vinyl Chloride) (PVC) Recycling
Poly (vinyl chloride) is one of the oldest thermoplastic polymers. Since the beginning of industrial PVC synthesis, in the early 1930s, its production volume has been constantly growing [ 1 ]. It is currently third in the world in terms of production volume [ 2 ]. Sodium chloride (rock salt) is one of the raw materials used in the synthesis of PVC.

How does the SDS addition in talc grinding affect its floatability?
The natural floatability of talc was compared to its floatability after adding the SDS in either grinding or flotation. The results proved a significant effect of grinding conditions on its natural floatability. The higher flotation recovery is achieved by grinding at the alkaline medium compared to the acidic medium at 30% solids.
