Coal tar is a common trapping agent used in the flotation of graphite ores, pine oil or butyl ether oil is commonly used as a foaming agent, and water glass and sodium fluorosilicate are commonlyAccording to Khraisheh et al. (2005), the cost of depressants is usually the highest compared to any other reagent at most flotation plants. In North/Central Queensland, Australia, the carbonaceous matter is reported to be depressed using dye depressants during flotation of sulfide ores.The differential depression of an oxidized starch on the flotation

The entrainment behaviour of sericite in microcrystalline graphite

Sericite is one of the main gangue minerals in microcrystalline graphite ore, it is also the main contaminant of flotation concentrate (FC ad = 88%) of the commercial microcrystalline graphite ore. Moreover, sericite reports into concentrate in base metal ores flotation, the mechanism that sericite reported into the concentrate was entrainmentA classification of flotation processes carried out in concentrated electrolyte solutions, e.g., seawater, is proposed using the most obvious features of these processes: low or high content of Mg2+ and Ca2+ ions, pulp ionic strength, and pH. The first distinguishable group is the processes carried out in NaCl/KCl solutions, about 0.5 M in Flotation in Seawater SpringerLink

The Recycling of Spent Lithium-Ion Batteries: Crucial Flotation

The recycling of spent lithium-ion batteries (LIBs) has attracted great attention, mainly because of its significant impact on resource recycling and environmental protection. Currently, the processes involved in recovering valuable metals from spent LIBs have shown remarkable progress, but little attention has been paid to the effective coarse grinding and rougher flotation stage with minimal grinding energy costs as against the usual practice of single stage grinding in the case of many ores. A final concentrate of 8.97% weight recovery with 5.80% ash and 92.13% fixed carbon could be achieved.
