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.
