  • Nickel Ore - an overview | ScienceDirect Topics

    The nature and origin of the sulphide nickel ore, and the water chemistry of the region also may dictate adoption of different flowsheets 7 as in the case of nickel ores in Canada (e.g., ores from Sudbury region and the Thomson region). The water chemistry and the utility of sodium carbonate or lime as pH regulators, play vital role during ...

  • Nickel Ore Sorting : TOMRA

    Sorting and dumping of waste rock at the shaft considerably reduces transportation costs of the upgraded nickel ore to the distant processing plant. In many instances, nickel mineral reserves that were previously uneconomic are now viable projects, which extend the life of the mine. TOMRA Sorting Solutions can help you sort the value out of nickel.

  • Enhanced methods for nickel recovery from low-grade ores ...

    A common method for nickel leaching from the matte is by using ammonia under high pressure, producing a nickel-bearing solution. This solution is heated to remove copper, and the use of hydrogen gas under high pressure precipitates nickel metal; remaining nickel in the solution can be precipitated by adding hydrogen sulfide.

  • EP0948655A4 - Recovery of nickel from bioleach solution ...

    A bioleaching method is provided for recovering a nickel from an ore selected from the group consisting nickel-containing lateritic ores and nickel-containing sulfidic ores or concentrates thereof. Where the ore selected is a nickel-containing lateritic ore, at least one micro-organism selective to the leaching of the lateritic ore is provided as an aqueous solution thereof maintained at a pH ...

  • Nickel Solution - Athena Allergy Inc. - Athena Allergy, Inc.

    Nickel Solution is a unique two-part system that gives you the freedom to wear the jewelry you love - not just "nickel-free". This invaluable kit is super easy to use. It contains Nickel Alert®, a dmg nickel spot test which is safe to test any metal item and know in 30 seconds if the metal contains even minute amounts of nickel.

  • Processing Nickel Ores

    The nickel and ammonia solution contains 2:2 ratio of nickel to ammonia (molar), which is roughly 50 grams nickel per liter of solution. The nickel-ammonia solution is then reduced with hydrogen in autoclaves, adding a a small amount of ferrous ammonium sulphate. This solution is heated to 250 deg F at 350 PSI, in a hydrogen atmosphere.

  • Nickel: smelting, producing-Metalpedia

    Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on .

  • Pentlandite - Wikipedia

    In these locations it forms an important nickel ore. Pentlandite is also the principal ore mineral won from Kambalda type komatiitic nickel ore deposits, the type examples of which are in the Yilgarn Craton of Western Australia. Similar deposits exist at Nkomati, Namibia, in the Thompson Belt, Canada, and a few examples from Brazil.
