The effects of partially replacing amine collectors by a commercial frother in a reverse cationic hematite flotation [PDF]
Heliyon, 2021 Iron ore froth flotation has recently been used to obtain pure minerals due to the depletion of high-grade deposits. Amine collectors have often been used in cationic reverse iron ore flotation to achieve the separation with quartz impurities.

On the frother’s strength and its performance
Minerals Engineering, 2021 Abstract It is a common rule that the strength of the frother is assessed by either its dynamic foamability index (DFI) or its critical coalescence concentration (CCC). The smaller the value of CCC the stronger the frother is. This general rule (CCC rule) however is superficial although being well accepted. Yet, there are critical questions about the

A new method of testing frother performance
Transactions of Nonferrous Metals Society of China, 2013 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]
Iranian Journal of Chemistry & Chemical Engineering, 2022 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
