Reagents in Iron Ores Flotation
Minerals Engineering, 2005The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda. Ether amines are by far the mostly utilised class of collector. The degree of neutralisation of the ether amine is an important process parameter.

Application of Quantum Chemistry in the Study of Flotation Reagents
Minerals (Basel, Switzerland), 2023 Flotation reagents are significant for modifying the interfacial characteristics of mineral grains to achieve the effective separation of minerals. Since the 1960s, when quantum chemistry was first introduced into the study of flotation reagents, many ...

Recent Progress on Chelating Reagents in Flotation of Zinc Oxide Ores: A Review
Minerals (Basel, Switzerland), 2023 Zinc oxide minerals (primarily smithsonite and hemimorphite) are important sources of Zn. Flotation is the most widely used method of enriching zinc oxide minerals for mineral processing.

Study on the Improvement of Emulsified Flotation Reagent
2012 Third International Conference on Digital Manufacturing & Automation, 2012Flotation experiments for Shanxi Dianping coal were carried out by diesel oil, ZFC and ZFC-1, and superior flotation parameter combinations of which were researched. The results show that ZFC-1 has better collectivity and selectivity to coal sample. The ZFC-1 clean coal recovery increases by 2.47% and 2.93% than diesel oil and ZFC, respectively, and ...

The effect of flotation reagents on grinding
Powder Technology, 1968Abstract A hematite-quartz ore was ground in a rod mill and the size analysis and surface area of the products were determined. The fineness of the ground product decreased as the pH of the pulp increased. During grinding, hydration of the new surface is accompanied by abstraction of hydrogen or hydroxyl ions.

The interaction of flotation reagents with reacting surfaces. A study on the flotation of cement
Chemical Engineering Science, 1985Abstract Fresh concrete can be separated into cement and aggregate by a single-step flotation process in aqueous suspension. The results of an experimental investigation comprising zeta-potential measurements, SIMS analyses and flotation tests are discussed.
