Flotation and cyanidation of a semirefractory g ore

Highgrade concentrates assaying 3050ppm of g was obtained by flotation column whereas conventional cells have yielded barely 510ppm of g concentrates. The recoveries were found to be more or less same in both the cases. Also, it is apparent that around 40% of the solids report to concentrate by conventional flotation, resulting in poor grades, whereas weight of the concentrate is below 10% by flotation column.
