Here is an Ancient Gold Ore Milling Process used in China in the 1800s We might use it again after WW3 At the time 1890 the Author said "There is of course nothing for us to learn from this imperfect and rudimentary gold-extraction process described here which is doubtless destined to disappear ere long before the progress of scientific mining now making itself slowly felt Using these toxic chemicals to release fine gold ores from rock is a process that has existed for over 100 years Mr McCulloch explains that beyond the risk of chemical exposure facing workers directly involved in mining operations these toxic chemicals are often also expelled into tailing dams with waste water from the extraction process

process of gold from tailings Gold Tailings: Hazards and Opportunities INN Tailings from gold mining operations can pose a threat to the environment and health of nearby communities Not only can this waste be harmful if it leaches into groundwater but it can also mean

Ore tailings at the terminus of a spiral concentrator are first split by a novel splitter box into value-rich and value-poor streams determined by the Curing and leaching process for metal ores tailings and any accompanying environmental as copper vanadium gold silver tin etc This ore is fed from the crusher into a small Crusher

Once the gold has been eluted it undergoes a process called electro-winning where the gold is precipitated calcined and smelted in the existing smelthouse The two eluate streams are kept separate to allow for accurate accounting of the gold produced by the respective high- and low-grade circuits The leach residues are combined before being

Tailings originating from the gravity concentration of a gold ore containing about 14 g/t Au have been treated by various beneficiation methods These tailings have been screened on the 147 and 74 micron sieves and the two coarsest fractions have been separated on shaking tables with unsatisfactory results but the concentrates have been examined in polished sections for

Similarly tailings dumps arising from the processing of chrome ore in the Lower Group reefs of the BC are also being retreated to recover PGEs Several commercially profitable enterprises have also been set up with the sole intention of retreating tailings dumps arising from South Africa's Witwatersrand gold processing operations

The slurry that remains after this process has a very fine particle size Typically 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand) Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to 'see' the gold in the leaching process

Historic Gold Mine Tailings FAQ What are gold mine tailings? Tailings are a by-product of a gold mining process that was common in the late 1800s and early 1900s Gold-bearing rocks that also contain arsenic were crushed and spread over liquid mercury to remove the gold The mercury was then evaporated leaving the gold
