ZIMSEC O Level Integrated Science Notes: Extraction of iron: The blast furnace. This burns the coke and in the process provide the heat required for the smelting process to take place Near the base of the furnace the carbon in the coke combines with oxygen to give carbon monoxide The equation for this process is: Carbon monoxide is formed because there is not enough oxygen to make carbon dioxide.

Our solvent extraction and refining plants are present in Zimbabwe, Zambia and Malawi, supplying substantial volumes to the local markets.
At LUT, solvent extraction has been used for purifying the solution. In this process, the separation occurs between two insoluble liquid phases. In this case, impurities, calcium and magnesium were separated from the concentrated lithium salt solution into an organic solution consisting primarily of kerosine.
