In this study, a new approach "coaloil assisted gold flotation" was used to recover gold particles. The coaloilgold agglomeration process considers the preferential wetting of coal and gold particles. The method takes advantage of the greater hydrophobicity and oleophilicity of coal and gold compared to that the most gangue materials.

Conventional gravity separation and flotation method alone cannot recover these kinds of ores effectively. On account of above problems, the coaloil agglomeration (CGA) method, whereby hydrophobic gold particles are recovered from ore slurries into coaloil agglomerates, and a subsequent recovery through smelting or cosmelting of these agglomerates, has been generally recognized by the ...
