Various processes are used to treat nickel matte. In electrorefining, the nickel is deposited onto pure nickel cathodes from sulfate or chloride solutions. (i) Name the method of refining of nickel. Answered Describe a method for refining nickel. NCERT P Bahadur IIT-JEE Previous Year Narendra Awasthi MS Chauhan. Method of electrolytic refining rough Nickel, including electrolysis with soluble anodes of rough Nickel, cleaning solutions from impurities, deficit reduction of Nickel in the electrolyte, characterized in that to compensate for the deficiency of Nickel in the electrolyte used solution from the leaching of secondary materials containing Nickel, cobalt and other metals, the sulfate-chloride electrolyte to the first stage … You may need to download version 2.0 now from the Chrome Web Store. Oxide ores, on the other hand, do not produce the same reaction heats, making necessary the use of energy from other sources for smelting. At the first stage, initial metallic nickel is subjected to zone chlorination. Drying of moisture and removal of the chemically bound water are therefore major operations. Nickel is refined by Mond's process. It is the selective distribution of the components of a mixture between the two phases: moving phase and stationary phase. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro- and carbonyl refined. Vapor processes, such as the carbonyl process, can be used to produce high purity nickel pellets. In cases such as the Sudbury deposit, where the copper content of the ore is almost equal to that of nickel, the concentrate is subjected to a second selective flotation whereby the copper is floated to produce a low-nickel copper concentrate and a separate nickel concentrate, each to be processed in its respective smelting line. Cloudflare Ray ID: 6158bd4d5cfd4c97 This is done in a rotating converter of the type used in copper production. Though carbonyl refining is an efficient method of producing high-purity nickel pellets and powders and requires little labor, it has disadvantages like the use of toxic and explosive gas and the need for a hydrometallurgical plant of recovering the nickel and by-products—metals. What is the name of this process? Join now. As these rise through the mixture, the sulfide particles adhere to their surfaces and are collected as a concentrate containing 6 to 12 percent nickel. NICKEL : Nickel is recuperated by extractive metallurgy. Join now. Nickel refining Various processes are used to refine nickel matte. They are then separated from the mother liquor in a centrifuge, and dried and bagged for shipment. Watch Queue Queue. However, the majority of laterite smelters produce a crude ferronickel, which, after refining to remove impurities such as silicon, carbon, and phosphorus, is marketed as an alloying agent in steel manufacture. The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. • Answer of Describe a method for refining nickel. Latest advances in hydrometallurgy have effected in current nickel processing maneuvers being built-up using these processes. answered May 20, 2019 by Anik (70.8k points) selected May 21, 2019 by Vikash Kumar . Nickel concentrates may be leached with sulfuric acid or ammonia, or they may be dried and smelted in flash and bath processes, as is the case with copper. 229910052759 nickel Inorganic materials 0.000 title description 74 239000010950 nickel Substances 0.000 title description 74 Method of producing pure nickel by electrolytic refining If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.
