/879/1/012021. This study aimed to investigate the applicability of coaloil gold agglomeration (CGA) assisted flotation to recover gold from a refractory ore. The ore with the grade of 25 g/t was tested with the CGAflotation process in six different size fractions from 38 to 300 urn using different collector types and dosages.

Coal Gold Agglomeration (CGA) was developed by BP Minerals and involves the selective recovery of oleophilic gold particles from an aqueous slurry into coaloil agglomerates. These agglomerates are allowed to build up to a high gold loading and are then separated from the slurry. The loaded agglomerates are burned and the gold is finally ...

The coaloil agglomeration process for gold recovery became known to the mining industry in the mid80s after the first related patent was approved. This process involves either the attachment of gold to oilagglomerated coal or the simultaneous agglomeration of gold with coal and oil.

This paper describes the use of coaloil agglomerates in flotation to increase the gold recovery from an ore containing fine gold particles. The effects of operating parameters on gold flotation recovery such as oil type, particle size of agglomerating material, agglomerate/ore and oil/ore ratios were investigated. The studies showed that petroleum oils are more effective than vegetable oils ...

from its ores. The Coal Gold Agglomeration (CGA) process was developed some years ago and has the advantage in that gold is recovered by a procedure which has little or no negative impact on the environment. A gold ore containing liberated gold particles is contacted with coaloil agglomerates, whereby the gold is recovered into the coal/oil phase.

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.
