Evolution of Alluvial Gold Mining Technologies
This work provides historical information and examines changes in the methods and equipment used in gold recovery and processing operations. Alluvial gold recovery methods, mainly based on gravity separation combined with mercury (amalgamation), have been applied since the early days of mining. Historically, mining gold from the riverbeds was first implemented in Ancient …

Gold Wash Plants
Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant. The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the …

Characterisation of alluvial gold exploration data to improve gold
Samples were washed over a sluice box to generate alluvial gold concentrates that were oven-dried at 100 °C. Magnetic fractions were removed with a bar magnet, before the gold recovery (Clark 2010; Mboudou et al. 2017).The weight of gold was divided by the in situ volume of samples to obtain the gold grade in g/m 3 (Rae et al. 2009).The mean total section grade …
