    Abstract: A method and an apparatus for the separation of the mineral components of a pyrite containing copper-molybdenum ore by flotation. The method comprises grinding the ore in the presence of soda ash in an open circuit to produce an aqueous ore slurry; subjecting the slurry to a collective flash flotation step (10) in the presence of soda ash and sodium sulphide to recover a first part of metal sulphides of the ore in the form of a first concentrate (C1); subjecting the tailings (T1) of the collective flash flotation step (10) to a grinding step (13) and to a collective rougher flotation step (14) to recover a second part of metal sulphides of the ore in the form of a second concentrate (C3); and subjecting the concentrate (C1) of the collective flash flotation step (10) and the concentrate (C3) of the collective rougher flotation step (14) to a selection step (12) to separate molybdenite from the other metal sulphides of the concentrate.

    Abstract: A method of extracting targeted metallic minerals from ores that contain sulfide metallic minerals along with oxide minerals, carbonate minerals, silicate minerals, halide minerals or combinations thereof. In the method, an ore slurry containing the metallic mineral in oxide, carbonate, silicate or halide form is provided. The slurry is activated by adding sodium thiosulfate and sodium metabisulfite, whereby the targeted metallic mineral forms an intermediary metal complex with the sodium thiosulfate and sodium metabisulfite. One or more metal release components are introduced into the ore slurry; whereby the targeted metallic mineral is released from the intermediary metal complex to form a metal sponge. This metal sponge is then subjected to a flotation process, whereby the targeted metallic mineral is drawn out of the ore slurry and thereby extracted from the ore.

    Abstract: This invention relates to the pH modifier in alkaline froth flotation processes to treat oxide and semi-soluble salt ores, such as phosphates, sulfates, carbonates and halides, to increase the recovery while generally maintaining or improving selectivity, thus the grade of desired minerals. The invented pH modifier is used to replace traditional alkaline pH modifiers—hydroxides, carbonates and bicarbonates, such as sodium hydroxide, sodium carbonate, lime and ammonia in anionic flotation processes. The pH modifier is aqueous solution, comprised of combinations of sodium hydroxide, sodium carbonate, and sodium silicate, along with sulfonated surfactant products, such as sulfonated petroleum oil, fatty acids, alkylates, ethoxylated alcohol ethers, and also sulfosuccinamates; and anionic polymers. The pH modifier is also used as a promoter for anionic collectors and as a depressant for gangue minerals.

    Abstract: An environmentally safe composition of matter for use as a promoter chemical in flotation separation of carbonates from industrial sand is disclosed. The promoter chemical replaces the standard petroleum sulfonate, glycol ether and nonphenol used in promoter chemicals with biodegradable substitutes permitting the waste from flotation separation to be disposed without fear of contamination of ground water. The biodegradable promoter is technically sound and causes little change to the flotation process.

    Abstract: The present invention relates generally to a process and an apparatus for flotation of sulphide minerals, such as sulphide minerals hosted in ores rich in magnesium minerals. The process involves grinding of the nickel ore rich in magnesium minerals and thereafter separation of the ground material into a coarse and fine stream of particles coarser than about 30 microns and finer than about 30 microns, respectively. Optionally, the fines stream may be further separated into a slimes fraction. The coarse and fine flotation streams are then fit to separate parallel flotation circuits. Acid and/or activator is added during flotation of the coarse stream only. Significantly improved recoveries and grades were obtained with reduced acid consumption.

    Abstract: This invention provides an improved method for the rougher flotation of phosphate ore using sodium carbonate to control the pH at about 9.6-10.5. The method facilitates improved recovery of phosphate from its ore; in addition the Bone Phosphate of Lime (BPL) of the phosphate concentrate increases, which provides further advantages in that subsequent steps are improved by virtue of receiving a feed of greater purity. There are also certain environmental advantages obtained when ammonia is replaced with sodium carbonate and the operational safety of the flotation system is enhanced when ammonia is replaced with sodium carbonate.
