nickel oxides and concentrates

Roasting (metallurgy)

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. Get price

Concentrates and Oxides

The resulting roasted Mo concentrate typically contains minimum ab. 57% molybdenum, and less than 0.1% S. Between 30-40% of Global Technical Mo Oxide production is processed into Ferromolybdenum and ab. 25-30% into different chemical products (Chemically pure Molybdic Oxides and Molybdates). Get price

XPS Interpretation of Nickel

Nickel is also used in the five-cent coins in the United States and Canada (called nickels). It also makes up crucibles that are used in chemical laboratories. One of its isotopes, nickel-56, is produced in type II supernova. The light curve of the supernova is associated with the decay of nickel Get price

Extraction and Refining of the Platinum Metals

The nickel oxide produced is then reduced to metal and cast into anodes In the meantime, nickel matte from the blast furnace operation is broken, crushed and ground in ball mills to 20 mesh. This material is then roasted to nickel oxide in oil-fired 17-feet diameter Herreschoff type furnaces with two hearths separated by an air gap. Get price
