    · 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! Metallurgical processing of metalliferous ores in general and gold oresIn cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution When gold dissolution is complete, the goldbearing solution is separated from the solids With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of oreGold Refining | From Gold Ore to Doré | World Gold Council· Of the top 20 goldproducing mines, most (38%) were from refractory gold ores, followed by heap leaching (30%) and freemilling cyanidation/CIP (CIL) (18%), and with 14% as byproduct gold from the smelting of copper concentrates It is useful to consider the process routes involved in processing these refractory ores Over half of the refractory gold from the top 20 operations in 2011Overview of the Gold Mining Industry and Major Gold
