OverviewRoasting operations

Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores. More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation. The concentrate is mixed with other mat

IntroductionGravity ConcentrationFlotationCyanidationRefractory Ore ProcessingHeap LeachingMerrill-Crowe RecoveryCarbon Adsorption RecoveryConclusionMan has held a fascination with recovering and acquiring gold almost since the beginning of time. This paper will attempt to put the multitude of recovery processes into a current day perspective. An underlying theme of this paper is that the mineralogy of the ore will determine the best recovery process and that metallurgical testing is almost always required to optimize a recovery flowsheet. The major categories of commercially viable recovery processes include the following: 1. Gravity separation 2. Flotation 3. Cy
