 · More water led to more gold mining (both alluvial and quartz) and more mobilised sediment. Improved recording and reporting of alluvial mining machinery by district mining surveyors in this period (late 1860 s–early 1870 s) also appears to have been a factor in the increase. A second, lesser peak occurred in 1879, at 18 million m 3.

Alluvial Gold Mining. Alluvial gold is found beneath the surface at the bottom of a creak or stream. Alluvial gold mining is the process of extracting gold from these creaks, rivers and streams and is generally considered to be the most environmentally friendly method of gold mining as a result of the reduced environmental impact when compared to underground mining.

The i350 is revolutionizing the world of alluvial mining and dredging the same way the i150 has impacted the world of hard rock mining. This is a gravimetric concentrator that uses enhanced gravity (G''s) to concentrate the ''free'' heavy minerals. It is also known as a centrifugal concentrator because of the centrifugal action of the spinning bowl.

When alluvial gold became scarce, miners turned to shaft mining. Shaft mining is a technique used by miners where miners would use picks and shovels to dig shafts or tunnels underground. These shafts were 1 metre squared and were up to fifty metres deep.

Alluvial Gold: Eluvial Gold: Relationship to primary source of gold: Fine gold and small nuggets Can be transported many kilometers from source of gold. Can be ancient alluvial gold deposits in ground lifted high above current stream levels. Large nuggets, may be closer to primary gold source. How is this type of gold transported

2.2. Alluvial Mining Techniques Present day alluvial mining techniques can be categorised into the following two main types: • Small Scale Artisanal Mining • Small to Medium Scale Mechanised Alluvial Mining. 2.2.1. Small Scale Artisanal Mining Very small family orientated miners, which are also called Artisan Miners, are analogous to

equipment used by ASM at alluvial gold sites in the Guianas.1 To accomplish this goal, a local ASM group, mining an alluvial gold deposit, agreed to allow the research team to collect eight samples of ore material immediately before it was to be processed by their sluice and eight samples immediately upon exit from their sluice.
