    Taking gold out of a sluice box, western North America, 1900s Using a sluice box to extract gold from placer deposits has long been a very common practice in prospecting and smallscale mining A sluice box is essentially a man made channel with riffles set in the bottom The riffles are designed to create dead zones in the current to allow gold to drop out of suspension The box is placed inNew MercuryFree Mining Resource from UN ENvironment Seeking to learn about gold mining without mercury? Then miners can employ gold recover methods such as direct smelting (described below), although many panning operations lead to directly recoverable gold Panning offers miners a low cost method of gravity concentration but it requires time and skill to be effective One of the majorArtisanal and SmallScale Gold Mining Without MercuryModern mining companies looking to improve operational efficiency are investigating new strategies for automation, data management, and smart and connected technologies for integrating mining processes and equipment But mining still starts with extracting mineral resources from the earth Here we’ll examine traditional and novel mining techniques The American Geosciences web site definesMining Methods Now and in the Future Advancing Mining
