The next step in the extraction of zinc is called roasting. The concentrated ore is finely ground into small pieces and then suspended in a rising stream of air. The sulphur content can be reduced hugely with this process. This also converts the zinc blende to ZnO which is way more reactive. The reaction occurring here is.
