25/09/2020· Here are the common five chrome extraction processes. For the rich ore with high chromium oxide content, single gravity separation or magnetic separation process can be adopted. For the chrome with low chromium oxide content, the combined process of gravity separation and magnetic separation usually gets a better index than the single process.
1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and
affects the flotation performance of the ore for each oxidation degree tested. For the majority of the oxidation states, oxidative pulp chemistry, delivered by electrochemically inert grinding media , resulted in better flotation performance and better selectivity of chalcopyrite against pyrite.
4. The method of claim 1, wherein said aqueous pulp is formed by mixing 24 to 27 pounds of chromite ore per 76 to 73 pounds of water. 5. The method of claim 1, wherein said pulverized ore prior to froth flotation is deslimed in water.Cited by: 2
06/02/2018· However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the golds hydrophobicity.
