The Knelson concentrator is an efficient, portable machine with a number of advantages. The unit uses less water than conventional sluices. The amount of concentrates saved is small (around 5% or less of the initial feed weight); so final cleanup is easier. The concentrator is portable and easy to use, and it efficiently recovers fine gold.Web

However, Knelson concentrator proved to be ineffective in the case of ultrafine flaky gold, i.e., below 15 μm present in flotation feed and products. Batch knelson concentrator is more versatile for precious minerals recovery within grinding circuit whereas continuous Falcon is a good scavenging unit for fine heavies with better yield [ 51 ].Web

Oxygen Concentrators. An oxygen concentrator is a medical device that separates nitrogen from the air around you so you can breathe up to 95% pure oxygen.
