Collectors Collectors commonly used in the flotation process of gold and silver ores include xanthate, black powder and butylammonium black powder. Kerosene and transformer oil can be used as auxiliary collectors. Oleic acid can also be used as a collector for gold-copper oxide ores.
This implies that a high concentration of calcium in the process water could possibly enhance the contamination of the iron ore with the flotation collector. In Paper III, the effect of calcium, silicate and a carboxylate surfactant on the zeta-potential and wetting properties of magnetite was investigated.

Dec 20, 2018The Froth Flotation Method is means separating minerals according to their different physical and chemical properties. According to classification, the flotability of gold and silver minerals is included in the first category of natural and non-ferrous heavy metal sulfides, characterized by low surface wettability and easy flotation, which can be flotation by xanthate collectors.
Deposits of low grade and high-phosphorus iron ores are spreading globally, however, the usage of this kind of deposits in the manufacturing of steel bounded because of the high-phosphorus content as well as depression of iron in which affect the quality of the produced steel. The Bajrawia iron ore deposit is one of the largest in Sudan but it only contains (35.5% Fe) and undesirable amount of
pre-concentration of iron ore by gravity or magnetic methods. The flotation method commonly applied is the one based on cationic flotation of silica and silicates, that is, reverse flotation . The reagents required for froth flotation are collectors, frothers and regulators, such as activators and depressants.
Figure 6. Flotation kinetics non scalped sample at collector dosage 35 g/t. Figure 7. Flotation kinetics scalped sample at collector dosage 35 g/t. The flotation kinetics results for the non scalped and scalped samples are presented, respectively, in figures 8 and 9, for
Froth Flotation of Iron Ores ScientificAcademic Publishing. Jan 2, 2012 The reagents used in iron ore flotation, including starch, amines and fatty acids, of fatty acids on hematite plays a key role in the direct flotation route. .. The mechanism of adsorption of fatty acids and other surfactants at the
iron ore, either iron minerals or gangue minerals can be floated using suitable collectors. Ifthe ore is of very low grade (i.e., AIZO J SiOz content is very high) iron minerals are floated directly using oleic acid orother collectors (Direct flotation). On the other hand, (if the gangue AIZO J SiOz content is relatively low) gangue minerals
The reverse cationic flotation is one of the main processes used by the iron ore industry. In this process, Laurylamine is the main collector for quartz, and starch is the depressor for the iron minerals.
