In the production of construction lime, only a small part of the extracted raw material is suitable for the production of a quality product, while most of the production volume passes into the category of substandard raw materials. The authors of this article developed a project for the processing of carbonate-containing raw materials to produce lime for construction purposes. It is shown that despite the high level of risks and significant financial investments necessary for the organization of new production, the economic efficiency of such a project is obvious, since the costs of eliminating potential environmental disasters greatly exceed the costs of construction of the processing complex.
