Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide usually chalcocite which can then be activated by the froth flotation plant. Sulfide smelting

Concentration or Dressing of Ores . The ores obtained from the earth contain large quantities of foreign matter. These unwanted impurities e.g. earth particles rocky matter sand limestone etc. present in an ore are called gangue or matrix. . Prior to the extraction of the metal from the ore it is necessary to separate the ore from. the gangue.

2017121With the depleting reserves of highgrade iron ore in the world froth flotation has become increasingly important to process intermediate and lowgrade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a centurys practice in the iron ore industry froth flotation has been established as an efficient method to remove impurities from iron ore.

2015831Concentration of Ores i. Hydraulic Washing This is based on the differences in gravities of the ore and the gangue particles. It is a type of gravity separation. In one such process an upward stream of running water is used to wash the powdered ore. The lighter gangue particles are washed away and the heavier ores are left behind.
Details
20191210Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation classification magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
