  • GCSE Metals | Revise how Reactive ones are Extracted

    Ores are mined from the ground on a large scale. They often need to be concentrated even more before the metal is extracted and purified. The economics of using a particular ore may change over time. For example, as a metal becomes rarer, an ore that only has a low concentration of the metal may be used when it was previously considered too ...

  • The Process of Metal Extraction from Ore

    The Process of Metal Extraction from Ore Metals are produced when metal oxides have their oxygen removed. The process of metal extraction from ore is dependent on the reactivity of the metal. Highly reactive metals are extracted by electrolysis. In order of decreasing reactivity, these metals are potassium, sodium, calcium, magnesium and aluminum.

  • Conversion of Ore into Metal Oxide

    To convert the concentrated ores into metal oxides, two processes are used. These processes are calcination (heating in inadequate quantity of air) and roasting the ore (heating in adequate quantity of air). Carbonate ores are heated in absence of air. The absence of air and heat converts the CO 3 into CO 2 and O.
