The first method on how is gold mined is known as placer mining, or sediment mining. This common technique on how is gold mined is rather low on the scale when it comes to ease of mining - very little efforts to excavate the earth are employed. And because gold is so valuable, every little bit of this precious metal is sought out, hence the careful efforts employed in placer mining. What happens is that the miner will use a gold pan and sieve through water that passes through it, eliminating sand and pebbles while keeping a close watch for every gold bits contained in the debris. This, however, is not a viable method on how is gold mined because it takes a long time to produce large amounts of gold

unless there is willing labor prepared to fuel the efforts behind sediment mining. Another method widely used is the sluicing technique which is evidently faster in producing gold. This technique makes use of a sluicing box that is placed strategically at certain spots on the stream so that water containing gold bits can pass through it. The gold particles will accumulate in the box, making it easier for miners to then collect the boxes and sieve through them and plucking up the gold bits.
In the process of mining gold, other metals are also collected along with it. Copper and silver are two such examples. From here we can deduce that gold mining is indeed a profitable venture because not only gold is produced but other precious metals that are useful in various industries are collected too.r.
