nickel extracted from ores

  • Ore

    2018 10 26ensp;0183;ensp;An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit.[1] The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements. The grade or

  • GCSE CHEMISTRY Extraction of Copper Thermal

    2017 3 27ensp;0183;ensp;Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.

  • Nickel

    2018 11 2ensp;0183;ensp;Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air
