Modelling gold particle adhesion to oilcarbon agglomerates
A process called coalgoldagglomeration (CGA) has been investigated for recovering gold since early 1980s Cadzow and Lamb, 1989, House et al., 1988. Although there are different derivative flowsheets for the CGA since then, the contacting and adhesion process of gold particles with agglomerates is the key element that always lies at the ...
