Table of ContentsAnalytical ProceduresAnalytical SchemeResults Fractionation according to specific gravity using heavy liquids generally referred to as floatsink analysis provides an attractive practical means for characterizing coal samples Coal is generally a mixture of light organic components with density less than about 17 gcm and heavier mineral matter with density

Originally developed and patented in 1919 the density separation is achieved with two components mechanical vibration and air fluidization Today TripleS line of density separators and stoners are being used in thousands of applications from cleaning of leafy spices and peppercorns to reclaiming copper from scrap wire and cable

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector such as diesel oil kerosene refined oils pine oil or xanthate ester enhances its floatability

Sink and Float PROCESS History and Development For many years there have been effected in laboratory work separations of ore particles of different specific gravities through immersion of the mixed particles in a medium of a true heavy liquid with a specific gravity intermediate between the specific gravities of the heavy and light particles to be separated

The Problem with separating Copper from Zinc by flotation The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present This is usually the case in ore deposits near the surface or in tropical countries where the annual rainfall is quite high
