A new method of testing frother performance
Abstract A new method of testing frother performance was proposed. Four parameters were tested: maximum foam volume, foam half-life, gas-liquid ratio and mean foam rise velocity. Among them the former two parameters indicate frother's foaming ability and foam stability respectively, and the latter two indicate water carrying ability and foam ...

An increase in the Copper Recovery of the Sarcheshmeh Copper Complex through Reagent Modifications [PDF]
In the flotation of sulfide minerals, particularly in the separation between pyrite and chalcopyrite, adjustment of the pH and reagents dosages is very important. Process auditing at the Sarcheshmeh copper complex showed that the pH in the rougher cells

Evaluation of frothers based on properties of the solids/liquid/gas system [PDF]
A methodology of selection of frothers for flotation process is presented in the paper. It is based on performing a series of fractionating flotation tests of a considered material at different doses of a selected frother and calculation of the mass ...

Effects of Flotation Reagents on Flotation Kinetics of Aphanitic (Microcrystalline) Graphite
The flotation method is widely used for the preliminary beneficiation of aphanitic (microcrystalline) graphite. However, there is limited literature regarding the effects of flotation reagents on the flotation kinetics of aphanitic graphite.

Classification of Flotation Frothers [PDF]
In this paper, a scheme of flotation frothers classification is presented. The scheme first indicates the physical system in which a frother is present and four of them i.e., pure state, aqueous solution, aqueous solution/gas system and aqueous solution/gas/solid system are distinguished.
