Chelating reagents for flotation
Minerals Engineering, 2007The paper provides a review of the studies performed, starting from the 1970 up to today by Italian National Councils Mineral Processing Institute, to develop application for the use of chelating reagents in the flotation of metallic minerals. A summary is given of the various phases through which the studies progressed, starting by employing ...

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.

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.
