  • Lime use and functionality in sulphide mineral flotation ...

    Lime is a relatively inexpensive reagent, making it the most frequently used alkali in mineral processing. Based on indicative (2019) bulk reagent prices (excluding logistics costs), the effective mol OH − yield per US dollar of reagent is approximately 200 for CaO, compared to 150, 70 and 50 for MgO, N 2 CO 3 and NaOH respectively.

  • Lime (material) - Wikipedia

    Lime is a calcium-containing inorganic mineral composed primarily of oxides, and hydroxide, usually calcium oxide and/ or calcium hydroxide.It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering.
