nickel smelting and refining process

Nickel Smelting and Refiningalso reduces the nickel oxide. Lateritic ores have no significant fuel value, and an electric furnace is needed to obtain the high temperatures re- quired to accommodate the high magnesia con- tent of the ore. Some laterite smelters add sulfur to the furnace to produce a matte for processing. Most laterite nickel processers run.nickel smelting and refining process,Nickel: smelting, producing-MetalpediaMost sulfide ores have traditionally been processed using pyrometallurgical techniques to produce a matte for further refining. Recent advances in hydrometallurgical techniques have resulted in significant nickel purification using these processes. Most sulfide deposits have traditionally been processed by concentration.

Like all other.nickel smelting and refining process,Smelting and refining | Glossary | Sumitomo Metal Mining Co., Ltd.At SMM's Toyo facilities in Ehime Prefecture, the copper concentrate pre-processing undertaken at Saijo uses pyrometallurgical processes and the nickel refining at the Niihama site uses hydrometallurgical processes entirely. The term "smelting" is used for the extraction of metal from ores using melting and heating.

Flash smelting - Wikipedia

Flash smelting is a smelting process for sulfur-containing ores including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel and lead production. A second flash smelting system was developed by the.

Emission Estimation Techniques Manual for Nickel Concentrating .

This handbook covers the concentrating, smelting and refining of nickel commencing from the delivery of ore to the processing facilities for crushing and milling, through smelting and to the production of +99% pure nickel at the refinery, for the nickel sulfide and nickel/cobalt laterite processes. It does not include extraction of.

How Nickel is Produced - Nickel Institute

Nickel occurs in nature principally as oxides, sulphides and silicates. Ores of nickel are mined in over 23 countries and are smelted or refined in 25 countries. Most important are Russia, Canada, New Caledonia, Australia, Indonesia, Cuba, China, South Africa, Dominican Republic, Botswana, Columbia, Greece and Brazil.

State of the art in nickel smelting: direct Outokumpu nickel technology

Experience of the direct Outokumpu nickel (DON) smelting process gained over the first ten years of operation is reviewed, including the significant environmental impacts. In 1995, production capacity at Harjavalta was increased from 17 000 to 52 000 t/year, by introducing DON technology, additional refinery capacity being.

Smelting and Refining Operations

The smelting and refining of some metals can have special hazards. Examples include nickel carbonyl in nickel refining, fluorides in aluminium smelting, arsenic in copper and lead smelting and refining, and mercury and cyanide exposures during gold refining. These processes require their own special precautions.

Metals Smelters and Processing - :: WorstPolluted : Projects .

Metal processing plants and smelters are facilities that extract various metals from ore to create more refined metal products. Metals include copper, nickel, lead, zinc, silver, cobalt, gold, cadmium, etc. Smelting specifically involves heating the ore with a reducing agent such as coke, charcoal or other purifying agents.

What Is Nickel Smelting? (with picture) - wiseGEEK

The next process in nickel smelting is refining the liquid matte, which is typically done with one of two processes. With fluid bed roasting, sulfides are added to the liquid matte and the two are roasted together, eventually leaving just the nickel metal. The other process is chloride-hydrogen reduction, in which the liquid matte.

TOXICOLOGICAL PROFILE FOR NICKEL

These ores typically contain 1–3% nickel. Pentlandite (Ni,Fe)9S8 is the principle ore. Pentlandite often occurs along with the iron mineral pyrrhotite and the copper mineral chalcopyrite, and part of the smelting and refining process separates the copper and iron from the nickel. The ore is concentrated by physical means (i.e..
