Electronic Structure and Oxidation Mechanism of Nickel

the Sherritt Gordon process undergoes two stages.9 Nickel is selectively leached out in the CuSO 4−H 2 SO 4−O 2 solution in the first stage, while the copper sulfides formed are subsequently dissolved in the H 2 SO 4−O 2 solution in the second stage. Therefore, most previous works on the leaching mechanism of Ni−Cu matte demonstrated

Nickel: smelting, producing-Metalpedia

After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel

Nickel Metal: It's Properties, History, Production & Uses

Jul 28, 2019· These intermediate products, which usually contain 40-70% nickel, are then further processed, often using the Sherritt-Gordon Process. The Mond (or Carbonyl) Process is the most common and efficient method to treat nickel sulfide. In this process, the sulfide is treated with hydrogen and fed into a volatilization kiln.

Sherritt International Wikipedia

The company was named after Carl Sherritt, an American citizen and teamster on local rail construction projects who, after becoming a trapper and prospector, staked copper prospects in the Cold Lake area of Manitoba; and J. Peter Gordon, a civil engineer who had also worked on the railroad construction. Eldon Brown was the company's first employee and general superintendent. The Sherritt process, hydrometallurgical cobalt extraction techniques that enhance recovery from nickel-c

Sherritt International Operations Metals

Nickel is a strong, lustrous, silver-coloured metal. Its principal values lie in its resistance to corrosion and oxidation and its strength at high temperatures. Used primarily in the production of alloys including stainless steel, nickel is used to make everything from highly specialized materials (such as airplane engines and medical

Nickel in 2020: Learn About This In-Demand Industrial

Dec 06, 2020· Further processing of nickel matte occurs using the Sherritt-Gordon process. With this technique, hydrogen sulfide is added to the molten material to remove copper. This leaves a concentrate of only cobalt and nickel. Solvent are then used to extract cobalt. This leaves a final product with a nickel concentration of more than 99%.

Chemistry of the Ammonia Pressure Process for Leaching Ni

The paper relates to the laboratory and pilot plant studies that have been carried out by Sherritt Gordon Mines Ltd., Metallurgical Research Div., in developing the ammonia pressure leach process for extracting copper, nickel, cobalt, and sulphur from high grade nickel concentrate produced from Lynn Lake ores, and describes in some detail the chemistry of the process.

ACID LEACH PROCESS FOR NICKEL COPPER MATTES by Sherritt

Claim 1. A continuous process for separating and recovering copper and nickel values contained in substantially non-magnetic nickel-copper matte, said process including: leaching finely livided particles of said matte in a first-stage pressure leach under an initial oxygen ovea-ressure of above about 10 psig and at a temperature above about 100 0 C in an aqueous acid sulphate solution having a

A History of Sherritt Fifty Years of Pressure

Jan 14, 2009· The typical feed in the early years was a concentrate from the Sherritt Gordon mine at Lynn Lake. It contained approximately 10% Ni, 2% Cu and 0.5% Co, the remainder being iron, sulphur and gangue. The leach process operated initially with two countercurrent stages, which were referred to as the adjustment and final leach.
