Long Harbour Nickel Processing Plant, Canada. Brazil-based Vale is the second-largest mining company in the world. Vales objective for the nickel processing plant is to process concentrate from the mine / concentrator in northern Labrador to produce finished nickel product and associated cobalt and copper products.
Processing Nickel Ores - Mine Engineer.Com
The tailings from these cells is sent to another flotation cell, to recover the nickel, and the concentrate is combined with the 3% nickel concentrate to produce a 12% nickel concentrate. Most nickel ores have several recoverable metals in them and the process if commonly a multiple stream of metals recovered. The copper concentrate is sent to the copper smelter and 99.99% copper cathode is produced in …

NICKEL AND COBALT RECOVERY FROM MESABA …
NICKEL AND COBALT RECOVERY FROM A BULK COPPER-NICKEL CONCENTRATE USING THE CESL PROCESS D.L. Jones, K. Mayhew and L. O‟Connor CESL 12380 Horseshoe Way Richmond, British Columbia, Canada V7A 4Z1 ABSTRACT CESL has developed a novel hydrometallurgical process for treating Cu and Ni sulphide concentrates, including bulk concentrates.
Nickel - Wikipedia
The process was patented by Ludwig Mond and has been in industrial use since before the beginning of the 20th century. In this process, nickel is reacted with carbon monoxide in the presence of a sulfur catalyst at around 40–80 °C to form nickel carbonyl. Iron gives iron pentacarbonyl, too, but this reaction is slow. If necessary, the nickel may be separated by distillation.
Cobalt extraction - Wikipedia
The residue is removed. A feed of matte and sulfide concentrate containing approximately 0.4% cobalt and 30% sulfur is pressure leached at elevated temperature and pressure in an ammoniacal solution to produce a solution of nickel, copper and cobalt. By boiling away the ammonia; copper is precipitated as a sulfide and sent to a smelter.
A New Process for Cobalt Nickel Separation
A new process has been developed jointly by CSIRO and CESL, for separating cobalt from nickel in an impure leach solution. The process uses synergistic solvent extraction (SSX) with commercially available reagents, but in a novel and efficient manner using kinetic factors.
Nickel Concentrate | AMERICAN ELEMENTS
Nickel concentrate is similar to powder in that it is made up of minute, dry particles of pure substance. Concentrate is also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications.
EDXRF Analysis of Nickel Concentrate and Filter Cake
Water is added for creation of a pumpable slurry that is treated with reagents during floatation for concentrating the nickel. The concentrate is further processed by smelting creating nickel rich matte while the impurities are removed as slag.
Nickel sulphide concentrate processing via low-temperature ...
The reaction mechanism of nickel sulphide concentrate calcination with NaCl comprises oxidation of the sulphides to sulphates with subsequent decomposition at higher temperatures and calcination durations. The role of NaCl in the process of calcination is in its interaction with the SO 2 emitted during sulphide
