During the 19th and 20th centuries there were numerous and vast gold rushes.  A gold rush implies a time period when mine workers voyage to a specific area that contains an immense amount of gold deposits. They extend far back as mining for gold and the days of ancient Egypt. Gold rushes begin by the detection of gold founded by individual miners. With slight training and experience, individual miners’ first activity is to wash the gold from the sand and grit using specialised instruments such as a gold pan or something similar. The second it is acknowledged that the capacity of gold-bearing sediment is grander than a couple of cubic metres the individual miners will construct rockers or sluice boxes. This construction allows for a minor group of people to wash gold from the sediment way faster than utilising gold pans. Achieving and extracting the gold with this approach implies close to no capital venture, with the exception of simple apparatus costs. Gold rushes resulted in major wealth which was widely spread due to reduced relocation prices with additional low entry obstacles.  There was a genuine feeling of a free for all regarding income flexibility, where any particular person stood the chance of gaining copious amounts of wealth, instantaneously. Gold rushes assisted outgrowth of migration settlement which often resulted in everlasting residency of fresh and innovative areas. Each mining rush has a normal alteration through increasingly advanced capital expenses, superior establishments, and improved focused knowledge. They may also evolve from high-unit value to lower unit value minerals. After the sluice-box stage, placer mining may become increasingly large scale, requiring larger organizations, and higher capital expenditures. Small claims owned and mined by individuals may need to be merged into larger tracts. Difficult-to-reach placer deposits may be mined by tunnels. Water may be diverted by dams and canals to placer mine active river beds or to deliver water needed to wash dry placers. The more advanced techniques of ground sluicing, hydraulic mining, and dredging may be used. Interestingly enough there are several occasions where several silver rushes occur due to the after math of gold rushes. Developments in transportation and groundwork lead to focus changes resulting in efforts moving from golf to silver and then to base metals. Around the world there are around 10 to 30 million minor miners. Roughly 100 million people are either directly or indirectly reliant on such small-scale mining. Source
