One such advancement, is the use of agglomeration drums in the heap leaching process. The process of heap leaching extracts gold from ore by piling up crushed ore and applying a leaching agent to permeate through the pile, separating the gold from the ore.
The Coal Gold Agglomeration 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 coal oil agglomerates, whereby the gold is recovered into the coal/oil phase.
Turn on sound Gold mine exploration is challenging and complex. It requires significant time, financial resources and expertise in many disciplines e.g. geography, geology, chemistry and engineering. The likelihood of a discovery leading to a mine being developed is very low less than 0.1% of prospected sites will lead to a productive mine.
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
The coal gold agglomeration process is a novel gold recovering technique, which has following advantages. Studies on gold recovery from amalgamation tailings by CGA process shows that about 88% gold can be captured by coal oil agglomeration and the gross gold recovery is more than 85%. fADVANTAGES OF USING CGA
In 1988, gold particles were first recovered by successful pilot trial of coalgold agglomeration process in Australia. The current paper reviews the importance of CGA in the production of gold ore and identifies areas for further development work.
