Flotation uses additional chemical reagents to make gold to become less dense than the gangue hence rising to the top. Leaching involves dissolving the ore in sodium cyanide or sulfuric acid to separate it. In conclusion, gold is among the most precious metal in the world.

Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides. This may be an alternative ...

Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35 recovery, and the best I have heard of is around 50 recovery.

Jun 06, 2018018332One part per trillion corresponds to one trillionth of the whole, or 110 12. Thus, to find out how much gold there is in the ocean, we must divide the amount of water in the ocean, 1.39 10 21 kilograms as calculated above, by 10 12. This calculation results in 1.39 10 9 kilograms of gold in the ocean. Using the conversion 1 kilogram 0.0011 tons, we reach the conclusion that there are ...
