摘要： A process of purifying silica sand comprises grinding sandstone, washing and desliming the ground sandstone to remove the major part of the clay-type binder, attrition-scrubbing the deslimed sand particles to release further amounts of binder therefrom, washing and desliming to remove said binder, drying and heating the sand particles, treating the hot sand with sulfuric acid to convert the iron oxides, ferrosilicates and ferro-aluminous impurities into water soluble compounds, attrition-scrubbing the hot suspension of the chemically treated sand to release the strongly adhering stains of said impurities, washing with cold water and desliming, conditioning the sand suspension with fatty acids or petroleum sulfonate collectors, a polyalcohol frothing agent and, if necessary, a mineral acid to bring the pH to from 1.5 to 7.0, carrying out a first froth-flotation to remove the remaining ferrosilicates and iron oxides, and carrying out a second froth-flotation with a fatty amine collector in the presence of sulfuric acid and/or hydrofluoric acid to activate the aluminosilicates and to remove the same at a pH of from 1.5 to 3.5.

摘要： A new "cold" process for the recovery of elemental sulphur from contaminated elemental sulphur products is described. Elemental sulphur is recovered by froth flotation from: contaminated base pads of elemental sulphur blocks, stockpiles of contaminated elemental sulphur; contaminated elemental sulphur rejects from industrial handling and hauling; complex sulphur agglomerate, reject by-product from hot melting processes which is presently unprocessable and discarded (or as is otherwise referred to as "sulphur crete melt residue"); contaminated products resulting from the exploitation processes using wells for the application of heat to reservoirs in order to recover elemental sulphur; and also from other sources of contaminated elemental sulphur in the oil and gas and other industries. This process comprises the steps of coarse screening, crushing, wet grinding, sizing, classifying. Then, the wet ground slurry at ambient temperature is treated by froth flotation, removing the elemental sulphur in the froth, and transporting the undesirable contaminants to storage ponds or subsequent land reclamation. The initial elemental sulphur froth from the first stage of flotation is cleaned one or more times by reflotations. The cleaned elemental sulphur-bearing froth is then filtered to remove excess water and to produce a filter cake.
