Flotation as a separation technique in the coal gold ...

A gold recovery method, called the coal gold agglomeration (CGA) process, whereby hydrophobic gold particles are recovered from ore slurries into coal-oil agglomerates, and the subsequent burning of these agglomerates to recover the gold, was developed some years ago. The objective of this study was to optimise the separation phase of the CGA ...

2005-9-1 · Using coal–oil agglomeration method for free or native gold recovery has been a research subject for many researchers over the years. In this study, a new approach “coal–oil assisted gold flotation” was used to recover gold particles. The coal–oil–gold agglomeration process considers the preferential wetting of coal and gold particles.
