摘要

对燃煤电厂灰分进行了脱碳除铁预处理，生产出含碳量为71%的碳精矿用于电力行业，浮选尾矿中的磁铁矿精矿可作为铁冶金的附加原料。确定了浮选药剂的最佳用量和浮选时间。为提高磁选用铁的浓度，建议对浮选尾矿进行脱泥处理。

Preparation of Fly Ash of Ekibastuz Coals for Subsequent Production of Alumina

Pre-processing of ash from coal power plants were carried out, which consists of its decarbonization and iron removal to produce a carbon concentrate with a carbon content of 71 % for reuse in the power sector and magnetite concentrate from flotation tailings as an additional raw material in ferrous metallurgy. The optimal consumption of flotation reagents and flotation duration were identified. To increase the concentration of iron intended for magnetic separation, desliming of flotation tailings was recommended.

期刊介绍： The Journal "Ekologia i promyshlennost Rossii" («Ecology and Industry of Russia») is aimed to promote acquaintance of the world scientific and technical public and specialists, interested in the problems of the environment protection, with advanced achievements of the science and engineering practice on securing of stable (self-supporting) evolution within the limits of the United Nations accepted recommendations (RIO 92 and RIO+20). A circle of papers includes basic researches and engineering decisions, analytical and methodical operations, reviews on journal subjects. The journal lays special emphasis on methodical elaborations, analytical investigations in the sphere of creating the ecological culture of the population, to the features of ecological education in higher schools of the country for the sake of actualization in specialists'' consciousness of the scientific necessity to know environmental problems of the modern civilization and paths of their settlement. Original papers and investigations of scientists and specialists on separate themes occupy an independent niche of issues under the «Cover story» heading. The journal task is to promote practical implementation of scientific and engineering decisions in the field of decrease of anthropogenic load on the biosphere and environment protection (open lectures, round tables, discussions and so forth). Ecology and Industry of Russia is an informational reference book about the newest developments of the Russian and foreign scientists and the companies realized in Russia, the CIS and Baltic countries, and far-abroad countries. The journal publishes information reports about holding in Russia and abroad the international, all-Russian and regional congresses, conferences, and symposiums related to the journal subjects.
