4.The Jameson Cell grew out of a longterm research program aimed at improving the recovery of fine particles by flotation The work started at Imperial College London, and continued when Jameson moved in 1978 to the University of Newcastle, NSW, Australia, where he is Laureate Professor 2015 Academic research 19691990

5.Floatability of gold depends on the nature of gold, size of fine particles of gold, shape of gold particles, chemical purity of gold, presence of impurities, composition of the films on the surface of golden particles, material composition of the ore When froth flotation can be extracted particles

6.COARSE AND FINE PARTICLE FLOTATION Mineral particle size is an important parameter in froth flotationIn 1931,Gaudin,et al[1] showed that coarse and extremely fine particles are more difficult to recover by froth flotation as compared to intermediate size particlesThis was approved by Morris[2]

7.The effectiveness and efficacy of flotation diminishes with the size of the particles However, the kaolin industry is unique in successfully using flotation with fine particle size feed Kaolin is valued as a white pigment and therefore the goal in kaolin flotation circuits

8.INTRODUCTION Flotation is the separation of particles from a mixture by causing some particles to collect on the surface of bubbles Floatation is an extractive process where various minerals can be selectively extractedthe separation efficiency between the valuable and the gangue FLOTATION process can be applied to relatively fine
