REFINING RECOVERY AND REFINING WITH JUST NITRIC ACID

how can you refine with just nitric acid? the answer is simple, nitric acid or our nitric substitute acid will desolve all metals except for gold. some platinum group metals (platinum,rhodium,etc) may not desolve. this is not an issue because if you sort your materials properly you will not have any platinum group metals in the mix.

Effect of H2O2 on the Separation of Mo Bi Containing Ore

Effect of H2O2 on the Separation of Mo Bi Containing Ore

Hydrogen peroxide (H2O2) is a strong oxidizer that causes non selective oxidation of sulfide minerals, and its influence on bismuth sulfide ores is not well documented. In this study, H2O2 was proposed as an alternative bismuthinite depressant, and its effect on a Mo Bi containing ore was intensively investigated by batch flotation tests.

Froth flotation

Froth flotation

For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector). The particular chemical depends on the nature of the mineral to be recovered and, perhaps, the natures of those that are not wanted.
