  • Nickel processing Extraction and refining Britannica

    Nickel processing Nickel processing Extraction and refining: 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. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production. The specific processes taken depend on whether the ore is a sulfide or a laterite. In the

  • metal Extraction of nickel from its ores Chemistry

    08/03/2014· Nickel can be extracted directly from its ore by reduction by hydrogen or carbon monoxide at elevated temperature at 600 ∘ C to 650 ∘ C: N i O + H X 2 N i + H X 2 O. N i O + C O N i + C O X 2. Also, it can be extracted by treatment with dilute sulfuric acid following by precipitation: N i O + 2 H X + N i X 2 + + H X 2 O. Share.

    03/05/2018· A rotary dryer is typically used to remove free moisture. Preliminary Reduction • Once ore has been dried, it is processed in a large-scale rotary kiln to remove chemically bound moisture, as well as the oxide component of the ore. This step is often referred to as pre-reduction. Reduction & Smelting • Nickel is further reduced and smelted in an electric furnace. A cooling step may be implemented after the smelting step, typically through the

  • Extraction of Nickel QS Study

    Extraction of Nickel . Main ore is Pentlandite; Nickel is extracted from ores through the Mond procedure, in which nickel oxides are purified throughout several steps into pure nickel metal. It is placed with hydrogen and carbon monoxide gases at 122 degrees Fahrenheit, which converts it to impure nickel. Nickel is also a magnetic metal below 653 degrees Fahrenheit. It is somewhat reactive with dilute nitric, hydrochloric and sulfuric acids. Ni is extracted

  • Extraction of Nickel Nickel Ore Mining Mining

    20/03/2019· The extraction of nickel process generally consists of crushing, sieving, washing, re-selection, grinding, and slurry concentration, or the nickel leaching method. The target element nickel distribution varies with the nature of the ore, mostly contained in fine-grained grades.

  • Direct extraction of nickel and iron from laterite ores

    The process consists of reducing the ore with hydrogen, extracting of iron and nickel in the form of volatile metal carbonyls, separating the metal carbonyls and producing high purity nickel and iron metals; and production of copper, cobalt and PGE concentrate by gravity or magnetic separation.

  • Separation of iron-nickel alloy nugget from limonitic

    To efficiently extract nickel from low grade limonitic laterite ore, a separation method of iron-nickel alloy nugget by self- reduction of coal composite limonitic laterite ore briquette was investigated. In this investigation, in order to decrease the separation temperature of iron-nickel alloy nugget, the selective reduction by control of C/O ratio was introduced and reductant added in the

    The mining of laterites is basically an earth-moving operation, with large shovels, draglines, or front-end loaders extracting the nickel-rich strata and discarding large boulders and waste material. The ore is loaded into trucks at the face, as would be the case in an open pit, and hauled to the smelter. New Caledonia: open-pit nickel mine
