Froth flotation is a process for selectively separating hydrophobic materials from hydrophobic. In some cases, for example, sulphides ores of copper, zinc and lead concentration is brought by this method.In this method, the advantage is taken of the preferential wetting of the ore by an oil.The finely ground ore is taken in a tank containing water and 1% of pine oil or turpentine oil. Mar 20, 2016 The treatment of such an ore by flotation or some other process of concentration has this purpose to concentrate the copper into as small a bulk as possible without losing too much of the copper in doing so. Thus there are two important factors. (1) the degree of concentration and (2) the recovery of copper.

The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore It is necessary to determine the suitability of a gravity concentration process before it is employed for concentration of an ore. The concentration criterion is commonly used for this purpose, designated C C displaystyle CC in the following equation (where S G displaystyle SG represents specific gravity )

Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore. Iron ore is smelted after going through beneficiation. The iron ore industry classifies the material by the concentration of the metal that is present after iron ore beneficiation has been completed. High-grade iron ore must have a concentration of 65% iron or higher, and medium grade of 62% to 65%.

The process of removal of gangue from powdered ore is called concentration or ore dressing. There are several methods for concentrating the ores. 2.2. Iron Ore Processing Circuit. The typical gravity concentration circuit used by Canadian iron ore processors is shown in Figure 2. For the two Canadian iron ore processing plants considered in this paper, hematite (Fe 2 O 3) and quartz (SiO 2) make 99% of the processed ore.
