in most cases, gold processing with cyanide leaching, usually with carbon adsorption, is still the core technology and the critical thing is understanding the mineralogy in order to optimise flowsheet selection and cost drivers, and get the best out of the process. is a little more complex for gold ores, as the optimal process flowsheet

gold processing - gold processing - mining and concentrating: the nature of the ore deposit determines the mining and mineral processing techniques applied. oxide ore deposits are frequently of such low grade e.g., 3 to 10 parts per million that extensive mineral processing cannot economically be justified. in this case they are merely shattered by explosives and then piled into heaps for
