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. metallurgy: the science of bashing, mashing and hashing
the process mineralogy of gold is not limited to the gold minerals, submicroscopic gold, and their carriers but also includes the study of gangue minerals and other species that may affect gold processing, such as cyanicides.
the flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. in a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. highly oxidized ores generally do not respond well to flotation. advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle

the basics of gold mining and processing. once mining engineers know where gold is located and what other materials surround it, the mining process can begin. if the gold is located close to the surface, its mined with open-pit mining techniques. gold thats located farther below the surface is collected with underground mining methods.
refractory gold processes. your gold concentrate will afterwards undergo ultrafine grind and go for the cheapest oxidation there is ie: atmospheric or low pressure oxidation before going to classic cil. this last more costly option is commonly known as pox or high pressure oxidation for the most difficult refractory gold ores.
