Retsch Flotation Tester FT 100 XL NEW
"Flotation is used in gold, copper, lead, zinc, and coal mining to recover fine mineral particles from ore slurry. This technique involves filling the slurry into a frothing solution to separate the particles. Due to their surface tension some particles float to the top with the air bubbles where they can be extracted; fragments which still contain large amounts of ore sink to the bottom of the tank as so-called “tailings”.
The laboratory flotation machine FT 100 XL is used to determine the percentages of the reagents required in a production flotation cell and for metallurgical sampling. A variety of flotation cells is available for use with the FT 100 XL. Tank and agitator are made of stainless steel. The machine is designed for a material fineness of 500 to 750 microns.
The FT 100 XL is a precise and reliable tool to obtain reproducible test results to ascertain the operational capability of flotation plants." (RETSCH)

"The flotation process involves mixing the finely ground sample materials by rotation with water and various chemicals. Air is then pumped through the slurry mixture and the mineral particles attach themselves to the bubbles and rise to the surface where a concentrated mineral froth is formed. The mineral froth is then extracted and the concentrated mineral is further refined. Waste rock particles drop to the flotation tank’s bottom as tailings." (RETSCH)
