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.

用于生产大量商业产品的煤炭废物处理技术联合体的概念

摘要

考虑了根据原材料的特性将煤炭开采和加工废物转化为商业产品的技术。结果表明，用煤渣生产建筑材料可能是最流行的。稀土元素（REE），铝和铁精矿的生产；用于水净化的凝结剂；燃料添加剂（发电煤）；研究了用于煤渣的冶金工业添加剂。首次提出了一种技术综合体的概念，该技术综合体使得可以在一个循环中从煤炭废物中获得多种可销售产品。开发了集成技术的基本配置，并选择了用于工艺流程的基本设备。
