Abstract: Glycol ether compositions useful for metal recovery by froth flotation and processes for making the compositions are disclosed. In one process, dipropylene glycol methyl ether (DPM) is propoxylated to give a composition comprising 4 to 15 wt. % of DPM and at least 20 wt. % of tripropylene glycol methyl ether (TPM). In another process, the glycol ether composition is made from a distillation residue which comprises DPM, TPM, and a basic catalyst. Extraction of the residue with water to remove some of the basic catalyst is followed by propoxylated to give a composition which comprises less than 15 wt. % of DPM, at least 20 wt. % of TPM, and one or more PO-based glycols. In comparative froth tests, glycol ether compositions of the invention meet or exceed the performance of commercial frothers.

Abstract: A continuous flotation process and apparatus for iron-containing sulphides in ores and concentrates of ores are disclosed. The process includes adjusting the pH of an aqueous pulp of the ores or concentrates of the ores to be in the range of 6.5-8.5 and thereafter adding a reducing agent to modify an iron hydroxide film on the surface of iron-containing sulphides in the ores or ore concentrates to enable adsorption of a collector onto iron-containing sulphides. The process also includes adding the collector to the pulp prior to, during, or after adding the reducing agent. The process also includes aerating the pulp to increase the pulp potential to a level sufficient to allow collector adsorption onto the iron-containing sulphides and thereafter bubbling gas through the pulp and subjecting the aqueous pulp to froth flotation to produce a froth containing said sulphide containing minerals.

Abstract: Method of separation that uses at least one organic chemical reaction to alter the molecular structure of a substance or substances (102) so that a mechanical method of separation can be used to cause the separation of one or more substances from one or a group of substances (104). The organic chemical reaction alters the molecular structure by adding at least one atom to the molecular structure or by subtracting at least one atom from the molecular structure. The mechanical method of separation uses the differing physical characteristics of substances to physically change the place or position of substances to remove or isolate the substances from a combination or a mixture absent any chemical reaction. The organic chemical reaction and the mechanical method of separation are used in combination to cause the separation of substances that otherwise could not be separated by the mechanical method of separation alone.

Abstract: Methods of increasing the rate of separating hydrophobic and hydrophilic particles by flotation have been developed. They are based on using appropriate reagents to enhance the hydrophobicity of the particles to be floated, so that they can be more readily collected by the air bubbles used in flotation. The hydrophobicity-enhancing reagents include low HLB surfactants, naturally occurring lipids, modified lipids, and hydrophobic polymers. These methods can greatly increase the rate of flotation for the particles that are usually difficult to float, such as ultrafine particles, coarse particles, middlings, and the particles that do not readily float in the water containing large amounts of ions derived from the particles. In addition, new collectors for the flotation of phosphate minerals are disclosed.
