Corundum Flotation Tailing
Corundum Mining | Processing Equipment | Flow Chart. Rubies are red due to traces of chromium in the corundum. All other colors of transparent corundum are called sapphires. Deep blue sapphires are blue due to the presence of titanium and iron. Synthetic corundum was first created in 1837 and in 1903 the manufacture of corundum became more ...
