May 15 32 Clean cheap method for extracting gold discovered by accident not only from ores but from the waste of electronic products where it is commonly bound cheap method for extracting gold Crush and mill the gold ore to dust like particl Ore is put into the crusher which breaks it up Water is added during the process which when mixed to the ore particles creates a pulp Zinc dust is added to separate the gold from the solution The gold is then put through a filter press which separates it from the solution Step

Mar 28 32 To assay gold using fire start by placing the gold into a heat resistant crucible Then add lead oxide sodium bicarbonate potassium carbonate and flour to create a flux and heat everything to between 1 100 and 1 200 degrees Celsius Next pour off the top layer of molten glass and pour the metal underneath into a mold to coolAug 11 32 In some cases gold cannot be removed by cyanidation alone Pyrometallurgy can also be used for gold extraction as well This can include smelting in which the ore is reduced to a molten state as well as drying and roasting in which other materials in the rock are oxidized to prevent them from hindering the extraction process

Feb 11 32 Method for extracting gold from gold ore First a single flotation method Single flotation is suitable for the treatment of coarse and medium grain natural gold ore The crushed ore enters the ball mill and will be finely ground into a flotation Gold ore separation uses comminution techniques to break down the excavated rock but the material hardly looks like a lustrous yellow orange metal In order to properly free this rich element from the rock the crushing stage has to be followed by a chemically active stage such as the cyanidation process or the carbon in pulp release method

Finally once the rock is fully crushed we get to the part about separating out the gold from the crushed rock Often this is accomplished simply by very careful panning Panning is the most suitable method if you only have an amount of rock less than about 15 or 20 pounds1 One way is by panning since gold is heavier than most other substances you can swirl water just fast enough that the gold stays in the pan while the other substances wash out Or 2 You can put everything into an acid that dissolves other substances and doesn t dissolve gold Or 3
