Abstract

Technologies for the conversion of coal mining and processing wastes into commercial products depending on the characteristics of raw materials are considered. It is shown that the production of construction materials from coal wastes can be most popular. The production of rare earth element (REE), aluminum, and iron concentrates; coagulants for water purification; fuel additives (energy generation coals); and additives for the metallurgical industry from coal wastes was studied. The concept of a technological complex, which makes it possible to obtain a wide range of marketable products from coal wastes in a single cycle, is proposed for the first time. The basic configuration of integrated technology was developed, and the basic equipment for technological processes was selected. The possible results of the implementation of this technology in industry are shown.
