Froth flotation with anisotropic particle collectors

In one example, a method includes providing a pulp composed of a combination of particulate materials including particles of a target material. The pulp is mixed with a collector composed of anisotropic particles having at least two separate spatial domains that have different physiochemical properties, and the mixture of pulp and collector is fed into an aqueous solution containing air bubbles.

REAGENT SCHEME FOR SEDIMENTARY PHOSPHATE FLOTATION
20190126291 · 2019-05-02 · ·

A process of phosphate flotation comprising: pulping phosphate ore with water to about 55% to 75% solids to produce an ore slurry; conditioning the ore slurry with a new reagent scheme to produce a conditioned slurry; subjecting the conditioned slurry to flotation to produce an underflow and an overflow; and collecting the overflow as phosphate concentrate. The new reagent scheme may comprise a combination of fatty acid, fuel oil, and fatty acid soap, and may not comprise a pH modifier. The process may also work effectively at a lower percent solids than conventional reagent schemes.

METHODS FOR FLOTATION RECOVERY OF VALUE MATERIAL FROM COARSE-SIZED PARTICLES

Methods and systems for the flotation recovery of value materials from sulfide mineral sources are disclosed. The flotation recovery of the value materials is performed in a fluidized bed flotation cell utilizing collector materials that include at least one hydrocarbyl group and at least one functional group including sulfur on the hydrocarbyl group, and the hydrocarbyl group includes 2 or more aliphatic carbons and 6 or more total carbons. The methods and systems of the present disclosure advantageously allow for improved recovery of coarse-sized particles, which reduces time and energy expending during sample grinding stages. The methods and systems of the present disclosure also do not exhibit the detrimental frothing behaviors which can be associated with long-chain collectors typically having 6 or more carbon atoms. The systems and methods can be incorporated into existing processing systems to treat samples before or after conventional processing stages.
