Dec 08, 2016· The Russian Academy of Sciences' Far East in partnership with the Complex Innovative Technologies of the Amur Scientific Center has discovered that by filtering Coal, they can extract Gold dust as reported in the article "Modern alchemy: Russian scientists discover how to extract Gold from Coal", Published 22 Nov, 2016, RT.
Gold is heavier than most other particles, so alternative methods typically use motion or water to separate the gold from lighter particles. Panning involves moving sediment that potentially contains gold in a curved pan with water and moving in such a way that any gold will settle at the bottom while the water and other particles will leave the pan.
DRD Gold, one of the first South African companies to abandon traditional mining to focus on extracting gold from tailings. New technology allows it to recover up to 40% of the gold left in particle form in tailings. DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in .

Nov 23, 2016· The discovery of gold lacing in coal is the result of 15 years of study from different fields. To create the gold, smoke created in burning coal goes through a hundred-fold purifying system. The residue is then flushed through a filter with water, allowing a gold concentrate to be extracted that is later used to make the precious metal.
After the coal is brought up to the surface by conveyors, it undergoes a process that removes sand and mud by immersing the coal in a solution of water and tiny magnetite particles. The different elements separate naturally. The coal floats while the other ores, called tails, sink to the bottom.
This causes gold to collect on the negative terminals. Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers ...
