  • Praseodymium

    Praseodymium is a chemical element with the symbol Pr and the atomic number 59. It is the third member of the lanthanide series and is considered to be one of the rare-earth metals.It is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties.It is too reactive to be found in native form, and pure praseodymium metal slowly …

  • Cadmium

    Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury.Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 through 11. ...

  • Metallurgy

    During Roasting: Sulphides are partially converted to oxides. Volatile impurities are removed . The free elemental forms of sulphur, arsenic, and antimony are removed as SO₂, As₂O₃, and Sb₂O₃, respectively. Calcination: The process of heating a concentrated ore in the absence of air to melt the ores is called calcination.

  • Strontium

    Strontium is the chemical element with the symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly chemically reactive.The metal forms a dark oxide layer when it is exposed to air. Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, calcium …

  • Smelting

    Smelting is a process of applying heat to ore, to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

  • Nickel

    Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are ferromagnetic at or near room temperature; the others are iron, cobalt and gadolinium.Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature. The unit cell of nickel is a face-centered cube with the lattice …
