    Manganese has no satisfactory substitute in its major applications in metallurgy. In minor applications, (e.g., manganese phosphating), zinc and sometimes vanadium are viable substitutes. Manganese is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties, as first recognized by the British metallurgist Robert Forester Mushet (1811–1891) who, in 1856, introduced the element, in the form of Spiegeleisen, into steel for the specific purpose of removin

    Limestone is a sedimentary rock, most of which originally formed by the accumulation of sediments on the sea floor (although some formed in fresh water). These sediments, which were afterwards turned to limestone rock, are composed of over 50 per cent carbonate minerals. There are three main components in limestone: calcite and aragonite.
