Polysaccharide Depressants for the Reverse Flotation of Iron
In reverse cationic flotation of iron ore the iron oxide minerals are depressed using natural polysaccharides such as starch, dextrin, guar gum, CMC etc. As Flotation is one of the most effective technologies for the upgrading of low-grade, finely grained iron ores. This method can also be applied to reduce the impurities Reagents types in flotation of iron oxide minerals: A review

Surface interaction mechanisms in mineral flotation:
This work provides valuable insights into the fundamental understanding on the interaction mechanisms of both non-deformable (e.g., minerals) and deformable (e.g., bubbles) objects in mineral processing, shedding light on developing improved industrial processes and chemical additives to manipulate the interfacial force-driven flotationThe ores are concentrated through froth flotation in the form of copper-sulfide or copper-iron-sulfide minerals (e.g. chalcopyrite, chalcocite and etc.), which are then melted in a high-temperature reheating furnace (± 1250 ℃). Due to the different types of ores, fluxes and additives during the pyrometallurgical process, the chemicalCopper recovery from copper slags through flotation

Pilot-scale extraction of iron from flotation tailings via
Iron tailings is the most common and largest mining waste, and given the serious social, economic, and environmental impacts caused by tailings, green and safe technologies are urgently needed for the efficient treatment of tailings. In the present work, efficient extraction of iron from flotation tailings via the suspension magnetization roasting Custo pH ® pH modifiers, float oils and flotation additives for superior mineral conditioning; (TDM) is an organic compound that is used as a collection agent for copper, zinc and iron sulfide ores. It is an effective primary collector of sphalerite. It is also stable over a very wide pH range. More on TDM .Mineral and metal processing Arkema Global

Effects of sodium salts on the sulfidation of lead smelting slag
Flotation test results revealed that sodium salt additives had different influences on the zinc grade and recovery at different temperatures. Na 2 CO 3 was the best additive in roasting for increase in zinc grade, due to the formation of metallic iron rather than iron sulfides.Review of reverse flotation of iron ore is presented with a focus on the polysaccharide depressants used and the corresponding adsorption phenomena. Iron oxide minerals have a special affinity for starch and other polysaccharides, and this special property facilitates their depression during the reverse cationic flotation of silica with Polysaccharide Depressants for the Reverse Flotation of Iron

this process in industrial field is the flotation of iron ores which is of two types: direct and reverse flotation. The later one is again based on two different types as cationic and anionic reverse flotation. In all these processes different types of flotation reagents are used. Another application is separation of malachite and azurite oreHowever, adding additives into molten copper slags may be prone to violent chemical reactions or safety accidents; thus, it is difficult to industrialize their applications.
