It is a process that works best for processing complex ore types, especially ores that are difficult to process using gravity methods. In flotation, a mixture of slurry (crushed ore and water) and frothing agents are added into a flotation machine. A tube releases air into the tank of the machine and an agitator creates air bubbles at the bottom of the tank.
inquiry Flotation method is more popular with large-scale miners although it is also used by artisanal miners. This is the perfect method for processing gold found in complex materials. The flotation method involves mixing your crushed ore with water and then you add frothing agents in a single floatation machine. You then use a tube to release air ...
inquiry It's only accessible today because of asteroid bombardment. Theoretically, it's possible to form gold by the nuclear processes of fusion, fission, and radioactive decay. It's easiest for scientists to transmute gold by bombarding the heavier element mercury and producing gold via decay. Gold cannot be produced via chemistry or alchemy.
