 — The theoretical foundation of the CGA process is based on the difference in free energy and was expressed as a function of the interfacial tensions and three-phase contact angles between gold, oil and water, together with the ratio of coal-oil agglomerate to gold particle radii, as the free energy is a measure of the thermodynamic stability and ...

In mineral processing the grinding comminution process is an integral part since it is often the bottleneck of the concentrating process, thus small improvements may lead to large savings. By implementing a Reinforcement Learning controller this thesis aims to investigate if it is possible to control the grinding process more efficiently ...

 — The practice of gold minerals beneficiation is optimized by using the information obtained from applied mineralogy. In this way, at the moment of development and select a process for treatment a gold ore, try to identify the gold minerals is the first step. Obviously, the detection of non-valuable minerals is important.

The thesis is oriented to alternative methods for cyanide leaching in gold processing. This thesis aims to show the methodology of new leaching processes, point out possible alternatives in the market for processing raw materials and approach the research process of new reagents on samples from waste after flotation processing of gold ores. The ...
