Oil 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 i.e., 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 – for sulphide ores, in addition, adhesion minerals processing of gold and diamonds. The product of oil agglomeration of coal is carbonaceous agglomerate or granulate.

There are many factors which affect the oil agglomeration process such as coal ranks, moisture content, pulp density or solid concentration, oil dosage or oil concentration, particle size distribution, oil types, agglomeration time, conditioning time, concentration of salts, pH, vessel type, impeller design, number of baffles placed etc., which can be categorized into process variables and design variables.
