摘要： Some mineral processing plants encounter difficulties in dewatering pulps using clarifier/thickener (C/T) equipment due to a layer of fine particles, air bubbles and chemicals formed at the top of the liquid in the thickener. Such layers are very stable and form a cap on the C/T. The dewatering performance of the C/T then deteriorates under these conditions, and a high percentage of solids is contained in the thickener overflow. A process for removing water from rock slurry containing a wide range of particle sizes in mineral processing operations has been developed. The process includes: (a) classifying the feed slurry into two size fractions, namely a coarse fraction and a fine fraction, (b) treating the fine fraction (and the coarse fraction if required) with a selected flocculant, and (3) thickening the flocculated slurry in sedimentation equipment to separate liquid from solids.

摘要： An improvement, of the technology for the reduction of viscosity of mineral slurries of high solids content using rheology modifiers during the preparation of slurries to be handled and stored. The improvement includes first, the addition of a combination of organic polymers and/or surfactants (dispersants) for the reduction of the viscosity of mineral slurries, and second, the addition of a stabilizer or thickener (shear thinning type of polymers) of a predetermined type and amount of these rheology modifiers.

摘要： A novel material with polyol and polyamine functionality derived from vegetable oils is described. This novel “polyolamine” may be cross-linked with multifunctional cross-linkers to form polymeric materials. This novel material is therefore useful for coatings, adhesives, foams, fibers, sealants and elastomers or other applications where urethanes and polyureas find utility.

摘要： A chemical process to improve the filtration performance for the removal of gypsum from phosphoric acid/gypsum slurry using a filtration aid that is selected from a class of polymers, lower molecular weight anionic polyelectrolytes, which previously have not been used for this application. The polymer is CMC or Carboxymethyl Cellulose, which is a polymerized cellulose ether. CMC is found to be extremely effective for phosphoric acid/gypsum slurry that was produced from igneous phosphate rock. CMC is also available in food grade, which is novel for filtration aids for the production of phosphoric acid which may be used for human or animal feed.

摘要： 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.
