Abstract

The platy talc content of natural talc is increased by grinding a talc ore to liberate the platy talc from the other forms of talc and other materials present, optionally removing from the ground ore most of the fines of particle size of less than 10 microns, forming a slurry of the remaining talc with a solids content determined as follows: .- 10 Microns.Platy con-.Per cent solids .fines removed..tent of ore..content of slurry .No.\sF 80%.\sO 80% .No.< 80%.\sO 15% .Yes.Any.\sE 25% subjecting the slurry to froth flotation, removing froth formed during the froth flotation and separating the talc contained in the floated froth. The talc ore is preferably ground to a particle size of about - 100 Tyler mesh although froth flotation can be obtained with particles ground only to - 20 mesh. The froth flotation may be effected in the presence of a depressant, e.g. dextrin, starch, glue or guar gum, and a water soluble frother, e.g. polypropylene glycol methyl ether, and methyl, ethyl and n-butyl alcohols, in an amount not exceeding 0.1 lb. per ton of solids. The pH of the slurry is preferably maintained within the range of 6.8 to 8.0 during froth flotation, e.g. by the addition of an acid.ALSO:The platy talc content of natural talc is increased by grinding a talc ore to liberate the platy talc from the other forms of talc and other materials present, optionally removing from the ground ore most of the fines of particle size of less than 10 microns, forming a slurry of the remaining talc with a solids content determined as follows:- .-10 Micron Fines.Platy Content.Percent Solids .Removed.of Ore.Content of Slurry .No. 80%.\sO 8% .No.<80%.\sO 15% .Yes.any.\yP 25% subjecting the slurry to froth flotation, removing froth formed during the froth flotation and separating the talc contained in the floated froth.
