Limestone Extraction Without Drilling and Blasting
For years, the limestone was extracted by drilling and blasting and then wet processed into clinker in the cement plant. In a move to increase productivity and reduce costs, IFCEM became the first cement plant in the Ukraine to initiate the transition from the wet process to a dry process, a measure that optimized the mining method for material supply.
