Gold recovery methods, which include gravity, flotation, amalgamation and leaching are again under scrutiny today to improve the recovery and decrease the deleterious affects of the processes on environment and human health. On the other hand, new gold recovery methods, which should be less harmful to the environment, in addition to providing higher recoveries than conventional gold processing methods, are also being investigated. In this study, the effects of the assay and particle size of gold ores on the efficiency of the coal-oil-gold agglomeration processes are investigated experimentally. The effects of these parameters are very important for determining the process efficiency for different ore types. In order to establish the effects of the parameters mentioned above, artificial ores, which have different grades and particle sizes, were utilized as feed materials in the experiments. In last decade, many researchers have studied the optimum oil, coal type and their consumption. Very encouraging results have been obtained (over 90% recovery) by working with high oil and coal consumption. In this study, the experiments were done by using these materials at minimum dosages to provide a method in the range of economic availability. At the end of our studies, it can be clearly said that applying the coal-oil-gold agglomeration method to assist gold flotation gives more desirable results in view of the agglomeration reagents and material consumption. © 2000 Elsevier B.V.
