An impact crusher is a piece of heavy construction equipment people can use to reduce the size of things like rock, waste concrete, and similar materials.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.
The flotation cells are divided into several parts roughing concentration and scavenging the exact numbers of stages for each part should be decided by test work to reach the best recovery and with the use of frothing agent and collecting agent the gold concentrate will be collected

GOLD FLOTATION The flotation process which is today so extensively used for the concentration of basemetal sulphide ores and is finding increased use in many other fields In 1932 flotation plants began to be installed for the treatment of gold and silver ores as aGet A Quote
The floating behavior of granules was mainly influenced by granule diameter 25–45 mm and substrate concentration NO 2 –N 50–250 mgL in the transition zone The optimum granule diameter to avoid flotation but with excellent settling performance was identified around 25 mm Additionally the granule size is more sensitivity to flotation than substrate concentrationGet A Quote
