摘要
The present work deals with gold grains recovery by means of coal-oil agglomerates. Among several hydrophobic materials used, a specific type of coal proved to be more suitable to form agglomerates. Diesel oil, kerosene and vegetable oils were used as agglomerants. Three gold-containing materials were used in this work: an artificial mixture of sand and gold particles, a gravity gold concentrate and a gravity tailing. The best results, namely 90% of gold recovery, were comparable to those obtained by amalgamation. The preparation of agglomerates was carried out in a simplified way, i.e., in just one step. This process can be looked upon as a valid technical alternative to amalgamation.
