WEBNov 19, 2004 · 1.. IntroductionA process called coal–gold–agglomeration (CGA) has been investigated for recovering gold since early 1980s Cadzow and Lamb, 1989, House et al., there are different derivative flowsheets for the CGA since then, the contacting and adhesion process of gold particles with agglomerates is the key element .
WEBOil serves as a bridge between coal and gold particles, whilst coal acts as a carrier and facilitates effective separation of the goldbearing agglomerates. The CGA method has proved to be effective if used to process liberated/free gold particles, such as those contained within alluvial deposits and some process tailings.
