2011-11-1 Froth flotation is a physicochemical process that has been used for more than a century in the concentration of copper sulphide minerals (Herrera-Urbina, 2003). This process is based on the wettability of mineral particles to recover the mineral species of interest and depress unwanted gangue.
A pulp of 80 mesh Calumet and Hecla slimes containing 0.45% copper, mostly native, with considerable mineral occluded in the coarser particles of gangue, was agitated five minutes 'with 0.3 pounds potassium xanthate, thenwas agitated for twenty min-- utes with 0.4 pounds steam distilled pine 011, all per ton of ore.

The ore is a sulfide copper ore containing heads of approximately: copper 0.45, iron 3.5, molybdenum 0.006, and zinc 0.06 per ore sample. Prior flotation of this ore has employed, in the flotation cell, the addition of pine oil as required to optimize froth, ordinarily resulting in a total pine oil concentration of about 0.24 lb./ton.
Froth Flotation. Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34]. From: Advances in Colloid and Interface Science, 2005.
2012-11-30 Copper-nickel ore from INCO mines, Sudbury, Ontario, Canada was used in the experiments. The approximate ore composition was pentlandite 4-5%, chalcopyrite 4-5% and pyrrhotite 30-35%. The ore was ground in a polyurethane lined rod mill with stainless steel charge to avoid any external iron getting into the flotation system.

2020-4-16 The mineral ore was crushed using jaw crushers and then grinded by grinders and milled using ball mills to sizes of 70% passing 75 microns. For each sample, coning and quartering respectively. Effect of particle size Selective froth flotation concentration of antimonite ore from a mixture of antimony, lead and arsenic ores
2019-11-28 Froth Flotation Process. This is the process for concentration of primarily sulphide ores. It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals. The process uses the difference in the wetting characteristics of minerals and gangue.
Each type of a manganese deposit is a problem by itself in the matter of selection of a proper method of concentration, depending on the manganese minerals and their gangue constituents. Hence, this work studied the effect of sodium oleate concentration variation on the froth flotation of manganese ore obtained from Madaka, Niger State, Nigeria.

Thus the sulphide ore comes on the top with the froth and oil. The remaining gangue particles which did not dissolve in oil settle down. The foam is removed and taken for further processing. Thus the minerals are separated by the froth -flotation process. This method is extensively utilized for Copper sulphide, lead sulphide and Zinc sulphide.
