SKORPION ZINC: OPTIMISATION AND INNOVATION
Sauconite is the largest contributor to the zinc grade with lesser amounts of zinc hydroxides. The gangue minerals are mainly quartz, K-feldspar and muscovite mica. The plant operation achieves an annualised zinc production of 150 000 tonnes special high grade zinc. The choice of SX technology was dictated by the need to upgrade the zinc …

Extraction of Zinc | Application Of Zinc Refining Process
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.
