Additional refining can enhance this purity to up to 95%. One method used for refining nickel, particularly from sulfide ores, is ammonia pressure leaching. In this process, nickel is recovered from the solution through hydrogen reduction, while the sulfur in the ore reacts to form ammonium sulfate, which can be utilized as a fertilizer.
Sherritt's nickel refinery in Fort Saskatchewan, Alberta (the Fort Site), produces around 250,000 tonnes of ammonium sulphate fertilizer as a by-product, which is then sold to Canadian farmers. A saleable by-product means less waste from the refining process and more food on the table for people around the world.
Outotec® Nickel Flash Smelting Process is a benchmark nickel-smelting method and a clear global leader in the world's primary nickel production from sulfide raw materials. Efficiency and improved environmental and in-plant hygiene have been the guiding principles in developing the process. ... The Niihama Nickel Refinery is the only refinery ...
The nickel raw solution coming from the leaching plant to cobalt extraction is cooled and washed with kerosene to prevent foreign organic substances from entering the extraction process. Cobalt extraction is carried out in sequential cobalt extraction cells, where the nickel raw solution flows countercurrent to the extraction solution.

The Clear Edge product range has been developed along-side our nickel producing partners with all refining methods and related process stages catered for. Whether processing laterite or sulphide ore, filtering nickel concentrates and de-watering tailings or process filtration stages related to the ancillary products like copper sulphate, lead ...
The ammonia-based flowsheet is similar to the sodium hydroxide flowsheet, except ammonia gas (or ammonium hydroxide when dissolved in water) is the reagent used in the process plant in solvent extraction operations. A similar flowsheet is used in Terrafame's nickel sulphate refinery in Finland.
Sherritt Gordon Process. The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a "speiss", rich in cobalt and nickel. The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air.
Ask the Chatbot a Question Ask the Chatbot a Question nickel processing, preparation of the metal for use in various products.. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high melting point of 1,453 °C (2,647 …
The two main processing methods for laterite ores are smelting and High-Pressure Acid Leaching (HPAL). Smelting is used primarily on saprolite ores to obtain an iron-nickel …
In 1954, the North Nickel Company of Russia started using the high-pressure process for nickel refining and producing nickel powders, or ferro-nickel composite powders. In 2003, Jinchuan Group Co., Ltd. of China built a production plant that uses the high-pressure process. In the high-pressure process, the carbonylation synthesis is carried out ...
