Coprocessing waste in the cement industry: A solution to ...
The cement industry can turn the waste problem into a valuecreating opportunity by using the waste to substitute fossil fuels and natural raw materials: the coprocessing. Coprocessing is the use of waste material as raw materials or as a source of energy, or both, to replace natural mineral resources and fossil fuels such as coal, petroleum and gas in industrial processes.
Raw Materials Used in Cement Industry CMA India
Limestone comprises 95% of core raw material for cement production. No wonder then that the cement sector governs demand, supply and pricing of limestone (as well as coal) to some extent. According to some estimates, around 180250 kg of coal and about tonne of limestone is required to produce a tonne of cement. Cement manufacturing consumes minerals such as gypsum, Quartz, bauxite, coal ...
