    PROCESS DESCRIPTION - University of New Hampshire

    PROCESS DESCRIPTION In a limestone contactor, water flows through a bed of crushed sieved limestone in a similar way as it would flow through a sand filter (Spencer, 2000). The pH of water that flows through the limestone bed will be adjusted until it nears equilibrium with calcium carbonate (CaCO3(s)). The components of a contactor include a ...

    Limestone for pH Adjustment in Industrial Wastewater ...

    Limestone is an alkaline agent with the ability to neutralize, or partially neutralize strong acids. The neutralization process occurs when strong acids, in intimate contact with limestone chips, react with Calcium Carbonate (CaCO 3, the primary constituent of limestone) to form water, carbon dioxide, and calcium salts. The following depicts ...

    Marble - University of Auckland

    Marble Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the ...

    What happens when acid reacts with limestone? | Questions ...

     · Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will

    How is Limestone turned into marble? | Yahoo Answers

     · Best Answer: Marble is a metamorphic rock resulting from regional or, rarely, contact metamorphism of sedimentary carbonate rocks (either limestone or dolomite rock) or metamorphism of older marble. This metamorphic process causes a complete recrystallization of the original rock into an interlocking mosaic of calcite, aragonite and/or dolomite crystals.
