Roasting is a process of heating of sulphide 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 materials to facilitate the process. The technology is useful but is also a serious source of air polluRoasting Archives Mineral Processing & Metallurgy,In metallurgy, the operation of roasting, as a preliminary to chlorination, has for its object the expulsion of the sulphur, arsenic, antimony and other volatile substances existing in the ore, and the oxidation of the metals left behind, so as to leave nothing (except metallic gold) which can combine with chlorine when the ore is subsequently treated with it in aqueous solution.
Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.Roasting an overview ScienceDirect Topics,N. Ahern, in Gold Ore Processing (Second Edition), 2016. 2.1 Oxidative Pretreatment. During roasting of gold ores and concentrates, mercury is released to the gas phase, with the extent of release dependent on the mineralogical composition of the roaster feed and on the roasting conditions (temperature, roasting atmosphere and roasting time)..
