Flotation Reagents - 911 Metallurgist
2016-6-8 Types of Flotation Reagents. Flotation reagents may be roughly classified, according to their function, into the following groups: Frothers, Promoters, Depressants, Activators, Sulphidizers, Regulators. The order of these groups is no indication of their relative importance; and it is common for some reagents to fall into more than one group. Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth

Flotation Reagent - an overview ScienceDirect Topics
This text is a condensed form of the fundamental knowledge of chemical reagents commonly used in flotation and is addressed to the researchers and plant metallurgists who employ these reagents. Flotation reagents are not only collectors and frothers, but include equally large groups of modifiers, regulators, depressants and activators. This latter group of flotation reagents is often neglected in

Coal Froth Flotation: Effects of Reagent Adsorption on
2006-4-28 The amount and quality of concentrate obtained from froth flotation of a coal are very important to determine the efficiency of the separation process. The shape and size of the bubbles in the froth directly affect the amount and purity of the concentrate overflowed during the froth flotation of the coal. The froth structure is significantly dependent on parameters such as the size of the ...
