15.5.3 Spiral Concentrator. The spiral concentrator first appeared as a production unit in 1943 in the form of the Humphrey Spiral, for the separation of chrome-bearing sands in Oregon. By the 1950's, spirals were the standard primary wet gravity separation unit in the Australian mineral sands industry.
Because gravity concentrators rely on gravity to generate centrifugal force down the spiral, gravity concentrators do not require electricity to operate, and do not contain moving parts. The result is a reliable, low-maintenance solution to slurry classification. Compact gravity concentrator designs increase available floor space and lower ...

Description of Hengchang Gold Centrifugal Concentrator Main work principles: Centrifugal gold concentrator is a relatively new type of gravity concentration apparatus. The machines utilise the principles of a centrifuge to enhance the gravitational force experienced by feed particles to effect separation based on particle density.
Oat gold, fine gold, micron gold (micros), and gold dust are all terms used for the smallest forms of gold. These minute particles get lodged under rocks and pebbles and collect on the top of bedrock. They originate from lode gold upstream that breaks apart and is washed downhill. The farther the gold tumbles, the smaller the fragments get.
When choosing between a Falcon gravity concentrator or a Knelson gravity concentrator, many mining operations choose to use a Falcon concentrator if they aim to recover fine gold. Why is that?
