Developing alluvial mining in Papua New Guinea can greatly boost the rural economies, according to Immaculate Javia, founder of Sustainable Alluvial Mining Services. Her project won the inaugural Innovation PNG 2019 Award, Small Organisation Category, and it could revolutionise the small scale mining industry. David James reports.
What Is Alluvial Gold?
March 3, 2011. 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 ...
