mining froth flotuation technique

EFFECT OF KEY VARIABLES ON COAL CLEANING BY FROTH

Coal slurry of 50 g/L concentration was prepared by mixing 450 g of coal of 150 m size in 9 L water. In similar to above methods, slurry was fed and froth flotation was carried out for 10 minutes. Froths and tailings were collected carefully and left for drying which were then analysed for % ash content.

AMIT 145 Lesson 5 Froth Flotation Mining Mill Operator

Froth flotation is a physico chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite, coal is naturally hydrophobic.

What is the importance of froth flotation in relation to

Sep 16, 2018·The importance of froth flotation process is that, it is easy to separate two sulphide ores present in a mixture (by adjusting the oil water proportion or by using depressants). Also this process is significant because it allows for the economic extraction of metals from lower grade ores.

In this sense, mining froth can be described as an aerated slurry that either occurs naturally or, in some cases, purposely created to assist with the separation of minerals. Froth flotation is an important step used for the recovery and upgrading of sulfide ores, allowing far more economic recovery of valuable metals from much lower grade ore.

Copper extraction

Copper extraction. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite ), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals.
