US9440242B2 - Frothers for mineral flotation - Google Patents

Frothing agents or frothers are chemicals added to the process which have the ability to change the surface tension of a liquid such that the properties of the sparging bubbles are modified Frothers may act to stabilize air bubbles so that they will remain well-dispersed in slurry, and will form a stable froth layer that can be removed before An improved class of flotation frothers - ScienceDirect,1 IntroductionAlthough a new reagent might result in an increase in mineral recovery of only about 1% over traditional reagents, this small improvement is of great ecomonic importance for industrial operations that process 50,000 to 100,000 tonnes of ore dailyMineral processing - Wikipedia,Dewatering is an important process in mineral processing The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue

Flotation - Mining Solutions : BASF SE

Flotation BASF’s Lupromin® flotation range includes collectors for non-sulfide ores, frothers, dispersants and modifiers that are applied in this widely used process, separating minerals from gangue by creating favorable differences in media hydrophobicityFrothers | Engineering360,Frothers are in many respects chemically similar to ionic collectors, and, indeed, many of the collectors, such as oleates, are powerful frothers, being in fact too powerful to be used as efficient frothers, since the froths which they produce can be too stable to allow efficient transport to further processingMineral Processing Introduction - MetSolve Labs,Mineral processing is a major division in the science of Extractive Metallurgy Extractive metallurgy has been defined as the science and art of extracting metals from
