Jul 23, 2014· First, refractory gold ore is ground as finely as possible – usually so the individual grains are much less that 100 micrometers. The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold's hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water.

Jan 02, 2012· With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

by conventional cells. • Gold concentrates assaying 50 ppm of Au was achieved by using flotation column as rougher cum cleaner cell. Whereas concentrates assaying 10 ppm of Au were generated by conventional cells. • Iron ore concentrates assaying around 2% AL and silica that are suitable for direct reduction process could be.
