WEBOil agglomeration [1] [2] is one of the special processes of mineral processing. It is based on differences in surface properties of desired and undesired minerals, carbonaceous coal particles and gangue minerals. It is used for dressing, dehydration of finely dispersed naturally hydrophobic minerals – most often coal, in the first tests ...
WEBThe coaloil gold agglomeration (CGA) process is used for oleophilic/hydrophobic free gold particles (1 to 100 pm) from various primary and secondary slurry sources. In the CGA process, oil (either vegetable, diesel, or kerosene) act as a bridge between the coal and gold particles, and coal as a carrier enables significant separation of gold ...
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.
