'gold l see full list on ga.gov.au gold has a very special place in human history. it has been treasured since ancient times and was the first metal used by humans, with simple gold ornaments among the earliest known metal objects. in ancient times, alchemists would spend their entire lives trying to turn other metals into precious gold. in 5000 bc, the egyptians found gold in the bed of the nile river and for thousands of years used gold for objects of adornment. when king tutankhamen died, his mummified body was partly covered with gold which was still shiny when it was discovered by archaeologists over 3000 years later! gold has featured in many myths and legends. king midas, king solomon, and jason and the argonauts were all legendary gold seekers. even fairy tales often mention golden objects such as eggs or harps, and most people have heard of the golden pot at the end of the rainbow. christopher columbus was in search of gold when he discovered america in the 15th century. gold had a significant historical rol see full list on ga.gov.au the most common natural method of concentration of gold is through the ancient action of hot fluid inside the earth's crust. fluids deep in the crust are heated by the earth's internal heat. these fluids often have moved through the rocks over a large area and 'dissolved'the gold. when these fluids cooled or reacted with other rocks the dissolved gold precipitated (came out of the fluid) in cracks or fractures forming veins. if the fluids move over a large enough area, and dissolve the gold for a long enough period of time, gold can be concentrated in amounts in the parts per thousand or even greater. in australia this concentration of gold took place in the earth hundreds of millions of years ago in the eastern states, and thousands of millions of years ago in western australia. as well as gold, the fluids can carry other dissolved minerals, such as quartz. this is why gold is often found with quartz. these are known as primary gold deposits and to extract the gold the rock contai see full list on ga.gov.au mostly, gold is spread throughout the rocks and soil around us but in such low amounts that it's not worthwhile trying to get it out. however, there are some places where there is enough gold to make it economic to mine. most gold mined in australia today cannot be seen in the rock, it is very fine grained and mostly has a concentration of less than 5 grams in every tonne of rock mined. the feasibility of mining low concentrations of gold largely depends on the price of gold. gold is bought and sold every day on international gold markets. the price fluctuates according to demand by buyers and the amount being sold by sellers. in a few places gold is sufficiently concentrated in the rocks for it to be worth mining. australia (especially western australia) is the one of the world's top producers of gold. about 60% of australia's gold resources occur in western australia, with the remainder in all other states and the northern territory. virtually all resources occur in primary deposi see full list on ga.gov.au there are both opencut and underground gold mines in australia but most of australia's gold production comes from opencut mines. earthmoving equipment is used to remove waste rock from above the ore body and then to mine the ore. waste and ore are blasted to break them into sizes suitable for handling and transport to waste dumps or, in the case of the ore, to the crusher. underground mining is used where the depth of ore below the surface makes opencut mining uneconomic. vertical shafts and declines (spiral tunnels) are used to move people and equipment into and out of the mine, to provide ventilation and for hauling the waste rock and ore to the surface. extensions of deposits mined by open pit methods may be mined later by underground methods beneath the old open pit. see full list on ga.gov.au the processing of gold ore involves crushing, treatment with chemicals, melting (smelting) and further purification. it is then poured into moulds where it cools and hardens as gold bars called 'bullion', which make the gold easy to stack and transport. the first stage of processing gold ore is crushing. the gold then needs to be separated from the resultant powder. coarse gold may be removed by gravity concentration. thepowder is mixed with water, the gold sinks and the other wastes are washed away. fine gold in crushed ore will be processed differently depending on the nature of the gold ore itself. freemilling ore is the name for when gold can be recovered by crushing, grinding and cyanidation (treatment with a dilute cyanide solution) without additional processing. in refractory ore the gold is locked in sulphide minerals, so to achieve satisfactory levels of gold recovery additional processing is required before cyanidation. sulphide minerals in refractory ores are converted t see full list on ga.gov.au highquality minerals and metallurgical processinggold milling plant / flotation cell machine ball mill secondary manufacturer/ portable grinding machine for in auction/ chrome ore grinding size analysis/ jenis dan tipe mill kaolin processing / stone crushing plant process line/ rubble ball mill suppliers/ secondary crushing equipment cone crusher/ layout deisgn of syid paper mills quartz
