Nickel processing - Extraction and refining | …
Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag. This is done in a rotating converter of the type used in copper production. The slag is drawn off, leaving a …
Concentrate Nickel Processing
Concentrate Nickel Processing Samsbistro.Nl Copper nickel flotation. based on this information and the need for separate processing facilities that would be required for each concentrate if separate nickel and copper concentrates were produced, the authors decided to produce a bulk sulfide concentrate and separate the copper and nickel further along in the process flowsheet.
Nickel
Nickel is obtained from nickel carbonyl by one of two processes. It may be passed through a large chamber at high temperatures in which tens of thousands of nickel spheres, called pellets, are constantly stirred. The carbonyl decomposes and deposits pure nickel onto the nickel spheres. In the alternate process, nickel carbonyl is decomposed in a smaller chamber at 230 °C to create a fine ...

Nickel Mining and Processing: Everything you …
The Nickel Mining Process. Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, stone processes and the extraction process. One of the most well-known purification processes is called the Mond Process, which is an extracting and purifying process developed by Ludwig Mond in 1899.
Nickel: smelting
Most sulfide deposits have traditionally been processed by concentration through a froth flotation process followed by pyrometallurgical extraction. In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted.

NICKEL MATTE CHLORIDE LEACHING
Nickel is recovered from the process solution by solvent extraction, using the reagent Versatic 10, with ammonia again being used to maintain a pH of 5 to 5.3. Unlike sulfate-based extraction processes, there is no signifi-cant gypsum precipitation since most of the sulfates have already been precipitated as part of the iron removal stage
