Mining machines are now more efficient because updated technology saves energy and reduces the number of harmful chemicals needed to extract desired material from its surroundings. Heavy duty, weather-resistant equipment is still necessary to extract, transport, and process minerals, ores, coal, and precious metals from soil, sand, and rock.

2020/9/13In gold plants, for example, a number of gravity devices, old and new, are being used to recover relatively coarse gold. Over the past few years gravity separators that take advantage of differential specific gravities in a high-gradient centrifugal force field (e.g., Knelson and Falcon separators) have been used successfully for gold.
