Sep 02, 2021 Sephaku Cement Dangote group has prioritised water management by monitoring its use and implementing water balancing programmes such as storm water management at its cement plants in South Africa. The Aganang cement plant, situated 40km west of Lichtenburg, is located in the North West province, which is a water-stressed region of the world.
The primary means of managing mercury emissions from cement kiln stacks is to limit the input of mercury to the kilns systems coming from raw materials and fuels. To this purpose the mercury content in all raw materials and fuels must be regularly measured and the respective results used to compile a mercury mass balance for each kiln system.

A method for producing portland cement includes adding stabilized electric arc furnace dust EAFD to the raw materials fed into the feed end of a rotary cement kiln to form a cement clinker. The untreated EAFD is preferably stabilized by forming a mixture of water, lime, and a cementitious reactant consisting of untreated electric arc furnace dust.
