The test results of flotation mode showed that biological reagent exhibited high effectiveness in separation of magnetite and phlogopite. On the other hand, flotation mode obtained the best result regarding the iron grade of concentrate 69.56 by using the bacteria culture growth phases of 8 d, being highly competitive as compared to mode .Author: Qing Teng, Quanbao Wen, Zhichao

Evonik produces an array of performance chemicals that serve the mining industry. At the core of that technical knowhow is the production of highquality reagents for reverse flotation of nonsulfide ores. Our Tomamine product line of ether amines is designed specifically for this type of mineral flotation.
reverse flotation magnetite amine annazakopane.pl. Reverse flotation studies on magnetite samples have revealed that the use of starch as a depressant of Feoxides has a hydrophilic effect on the surface of Febearing sili es and significantly decreases Fe in the silicarich stream when used in combination with an amine Lilaflot D817M .

Flotation Reagent, Flotation Agents . Due to the different ore properties, the dosage range of flotation reagent is also different. Even for the same type of ore, there are also some differences in the formation of ore deposit, so the content of useful minerals and gangue vary, and the dosage of flotation reagent required in the flotation process are also different.
Magnetite Separation Production Line is used to single magnetite with simple ore properties. Process introduction. Weak magnetic reverse flotation process its a process that divides into weak magnetic positive ion reverse flotation process and weak magnetic negative ion reverse flotation process , the difference is the reagent , negative ion advantage
