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 ...

Free gold recovery by coaloil agglomeration Sabinet African Journals

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.

Utilization of coaloil agglomerates to recover gold particles

The present work deals with gold grains recovery by means of coaloil agglomerates. Among several hydrophobic materials used, a specific type of coal proved to be more suitable to form agglomerates. Diesel oil, kerosene and vegetable oils were used as agglomerants.

Use of coaloil agglomerates for particulate gold recovery

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.
