Reuse of Lime Kiln Dust from Quick Lime Manufacturer
Summary
Cockburn Cement supplies lime kiln dust from its quick lime operation to HIsmelt (direct smelting pig iron trial plant) for their desulphurisation process. There is potential for the cement producer to take the gypsum (produced from the desulphurisation process) in return and use it in the cement making process as raw material. The latter exchange will depend on the suitability of the gypsum properties for the cement process; this will be known once the HIsmelt plant is fully commercially operational. The cement producers also supplies lime kiln dust to a titanium dioxide pigment plant (Tiwest) for chlorine removal in their chlorination process.
