Flotation Chemistry of Hematite/oleate System
Oleate flotation characteristics of hematite have been investigated in thjs study under a wide range of experimental conditions of pH, temperature, ionic strength and collector concentration. The study revealed the following major features of this system which include: (a) a maximum in floatability in the neutral pH range; (b) an increase in the flotation response of hematite with increase eith...
متن کاملProcessing of Low Grade Fine Manganese Ore Using Flotation Method
Application of gravity and magnetic separation methods to upgrade low grade Manganese ores from Venaj Mine has been reported elsewhere. This paper discusses the results of flotation tests, as well as combination of flotation and magnetic method to concentrate fine particles (less than 150 microns) of manganese ore. Results obtained from various direct and reverse flotation tests, using differen...

متن کاملA reinterpretation of the hydration of micelles of dodecyltrimethylammonium bromide and chloride in aqueous solution.
The hydration of dodecyltrimethylammonium (DTAB) micelles is reinterpreted in light of the results of the companion paper (immediately preceding this paper) that showed that the location of the spin probe 16-doxylstearic acid methyl ester (16DSE) changes as a function of the aggregation number, N, of anionic micelles, i.e, that it does not conform to the zero-order model (ZOM). The ZOM requires...
متن کاملMorphology characterization and single-molecule study of DNA-dodecyltrimethylammonium bromide complex.
DNA compaction induced by dodecyltrimethylammonium bromide (DTAB) is studied using atomic force microscopy (AFM) and magnetic tweezers. The morphology of DNA-DTAB complex is dependent on the DTAB concentration and incubation time. With magnesium ions, the complexes show rod- and network-like structures after approximately 5 min of incubation at low DTAB concentrations. With increasing incubatio...
