Component composition of the processed forming mixture and mineralogical recommendations for its re-use

Abstract

Modern industrial production is aimed at the development of waste-free technological processes, wider use in the production of waste and by-products. The largest amount of waste is generated from the activities of mining and metallurgical enterprises. One of the problems of foundry production is the disposal of multiton solid waste, about 90% of which is spent molding mixture. Part of the spent mixture is reused as recyclable, but the main mass of it is collected at municipal solid waste landfills. This work is devoted to the study of the component composition of foundry production waste – spent molding mixture with the aim of its reuse. According to the results of the research carried out by the authors, mineralogical recommendations regarding its reuse were provided. Involvement in the reuse of spent molding mixture will allow to free up part of the solid household waste landfills, reduce the negative man-made load on the environment, and additionally obtain conditioned restored molding sands.
