Though gold was won from hard-rock deposits in ancient times, most gold until perhaps 1900 was won from riverbeds, and was traditionally called alluvial or placer gold. Prospecting for alluvial gold required relatively little equipment and always attracted hardy pioneers willing to forego the comforts of society in the hope of 'getting rich ...
Aeons of weathering has worn them down and redeposited the gold in the soil and creek beds as secondary (alluvial) gold deposits. Gold nuggets are formed in this way. More than 2.5 million kilograms of gold has been mined in Victoria, almost half of it from reefs, the remainder from alluvial deposits.
This setup is an alluvial gold process plant. The loader feeds the raw material into the hopper, and the stone enters the plate feeder from the lower part of the hopper; the material is into the Derocker, and then fed to the rotary scrubber evenly, the larger than 50mm scrap will be separated by Derocker and transferred to the ground as a waste pile.
