Gold processing 101 - Mining Magazine

 · In most cases, gold processing with 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. Metallurgy: the science of bashing, mashing and hashing!
