Mineralogical rationale for solving environmental problems of mining regions

Abstract

The copper ore mining in Bor was started at the beginning of the twentieth century. Parallel to this, the ore smelting was carried out in the first period. After construction of the Flotation Plant (1934), the ore dressing was performed and obtaining the concentrate of copper and precious metals. Until the 60's of the last century, the ore processing, obtained from exploitation from the copper deposits Bor (the Old Open Pit and underground mine Jama Bor), was carried out. After this period of ore obtained from the Bor mine, the ore from the deposit Lipa, Cerovo (Mali Krivelj) was also processed. Technogenic waste of flotation was obtained as by-product of this process by flotation that was disposed from 1934 to 1980 in the area of the Old Flotation Tailing Dump in Bor (Field 1 and Field 2). Based on the previous geological explorations in the mentioned zone, the increased copper contents were indicated in the subject area. The implementation of detailed geological explorations would evaluate the potentiality of the area, in order to review the possibilities of raw material leaching, as well as solving a serious environmental problem in the center of the town of Bor.

Innovative Technology of Using Anti-sand Filters at Wells of the Vankor Oil and Gas Field

“…Studies confirm that during the removal of rock particles from the reservoir in the operation of wells in the bottom zone form the high permeability channels of various widths and lengths of fractures along and bedding planes, by which the bulk of gas and produced water is filtered (Ozhogina et al 2017).…”

Preliminary mineralogical assessment of the Kuznetskaya coal preparation plant wastes

“…Данные минералогического анализа позволяют сделать вывод, что изучаемый материал относят к техногенным минеральным отходам первой группы, т. е. сырьё сходно по своему вещественному составу и свойствам с природным [3]. Потенциально такое сырьё можно вовлечь во вторичную переработку, применяя те же методы обогащения, которые используются на обогатительной фабрике при переработке первичного сырья.…”

“…Для создания технологии комплексной переработки горнопромышленных отходов необходимо тщательное изучение их вещественного состава, особенностей строения минеральных агрегатов и выявление форм нахождения потенциально опасных элементов [3]. Эту задачу невозможно решить без применения современных методов минералогического анализа с позиций двух главных направлений: технологической минералогии и динамично развивающейся в последние годы экологической минералогии, которые тесно связаны между собой.…”

Development of Methods for Anti-filtration Formations Destruction Inside a Heap Leach Pile

“…The presence of low permeable soils is one of the most difficult problems of metal extraction during heap leaching (Ozhogina et al 2017;Vorobyov et al 2017).…”
