Mining for gold is an ancient practice and is still one that is going strong and the equipment and mining supplies that are required depend upon the nature of the operation and where the gold deposits are located. Wh ether the gold is in sediment or hard rock, the type of items needed will vary.
When the gold is being refined from the ground there are several different ways to extract the gold from sediment. The most ancient of the ways to do so would be gold panning, however, it's not a very successful technique. The mining supplies needed for this is a pan where the gold will settle to the bottom of the pan since gold is extremely dense. The better way in sediment would be with a metal detector because this procedure is much faster. The third way is called sluicing and this is done by running very powerful streams of water past the gold deposits, this can be done in troughs, large canals or directly on a hillside.
The mining supplies for sediment mining are flat metal pans, filters, troughs and water wheels, shovels, picks, wheelbarrows or conveyor belts. All of these items are designed to help gold mining operations.
Dredging is another way of mining gold and thi sis done on a small scale by some mining corporations. They use a sluice box and drag it along the bottom of a riverbed or along the soil and there is a suction hose attached and controlled by a miner it will suck out ore deposits. The mining supplies need for this would include dredges, trucks and other machines ordered by the mining company.
When gold is found in hard rock and not in sediment the mining becomes more intense. This is when open pit mining will be used and this requires big heavy equipment to dig a mine in the side of the deposit or mountain, this of course is environmentally harmful. Other mining supplies or equipment used would be tunneling equipment.
Even though it is quite dangerous some mining companies still include in their mining supplies cyanide for cyanide processing. This is quite harmful but still seems to be an industry standard. They use the cyanide to extract the gold from rubble that's broken up on the ground. They spray it with cyanide and it will eat away all other metals and expose the gold.
