Australia's first refined lithium was produced in the form of lithium hydroxide from the Kwinana plant in May 2022. Kwinana is shared in a joint venture (JV) between Tianqi Lithium Corporation (51 per cent) and IGO (49 per cent). The JV partners will look to ramp up Kwinana to a nameplate production capacity of 24,000 tonnes per annum.

The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. The oxides are then reduced in a blast furnace that is 80100 feet high and about 25 feet in diameter (Figure 2) in which the roasted ore, coke ...

The second step involves either smelting or leaching to remove a large proportion of impurity particularly iron and in the case of sulfides ore, sulphur. The final step, refining, removes the last traces of the impurity elements and produces a copper product of percent purity (McGrawHill Encyclopedia, 1998).
