Gold mining is generally undertaken either using alluvial mining, where gold is mined from the alluvial deposits of the flood plain, or larger scale mining, where ore is blasted out of rock either from an open-pit or underground void. The impacts of the less conventional alluvial technique are scarcely explored in the literature.

We carried out the present study in soils impacted by alluvial gold mining in the Madre de Dios Region (Fig. 1).The impacted areas were selected according to the two locally most used technologies to extract sediments: Highly Mechanized Mining (HMM) and Minimally Mechanized Mining (MMM) (Fig. 2).HMM uses heavy machinery such as …
Alluvial/Placer gold deposits are gold-containing sand-mixed sediments formed after long-term weathering of vein gold deposits.Alluvial gold mining means mining from land surface or river or underground. Gold is in a free state in the sediments, and the difference in specific gravity between sand and gravel is obvious.
Alluvial is a term that refers to soil sediments and the various sand, silt, gravel, clay or other deposited matter left behind by flowing water. "Alluvial gold" refers to the type of gold dust found in that kind of soil. When the beds of rivers or streams are scooped and panned for gold dust, the product is referred to as alluvial gold..
