Major industrial need. Limestone comprises 95% of core raw material for cement production. No wonder then that the cement sector governs demand, supply and pricing of limestone to some extent. According to some estimates, around 1.5 tons of limestone is required to produce a ton of cement. Cement manufacturing consumes …

Limestone is used as a filler in a variety of products, including paper, plastic, and paint. The purest limestone is even used in foods and medicines such as breakfast cereals and calcium pills. Limestone is also the raw material for making lime (CaO) that is used to treat soils, purify water, and smelt copper. Lime has many additional uses in ...
