| Enrichment technology for fluorite carbonate-bearing ores |
FinancingR&D period: years 2007–2012. Budget financing and extra-budgetary resources attraction. Brief descriptionHigh selectivity performance of ТТ.соли N-n….N-… with respect to fluorite secures necessary separation selectivity of fluorite and calcite during their flotation processing. The froth products improved stability during flotation is conditioned by heteropolar salt molecule structure.  The technology has undergone tests and is implemented into industrial production. The technology has been implemented at Yaroslavski GOK, Russkaya Gornorudnaya Kompaniya LLC (Primorski Krai, Russia), Technologies testing works certificates dated 15.12.2006 and 21.11.2007.
The known analogues utilize steaming operation, at least 7 recleanings using liquid silica glass, which stipulate high energy and reagent consumption as well as tough sanitary-hygiene working conditions; those techniques can not be used for poor fluorite ores processing; during flotation big volumes of stable foam are created, the process is destabilized and additional defoaming systems are needed that include pipes, flumes, block-pumps. Competitive advantagesMarketing studies were not conducted. The technology can be used for poor ores processing. Due to functioning of activator, which is applied simultaneously with collector and is preparing fluorite immediately before the collector action, flotation effectiveness is provided without external heating of pulp, at conventional temperatures. The proposed technology enables it to raise the degree of fluorite extraction and to secure fluorite concentrate quality without pulp heating with simultaneous sanitary-hygiene working conditions improvement. Increased effectiveness and operational economy are provided by optimal temperature parameters and reduction of energy consumption. Guaranteed economic effect is achieved by:
Black oil savings will amount yearly 20-25 tons per enterprise. Social effect consists in improvement of working conditions due to reduction of pulp fluid phase steaming. Scientific significanceA process is scientifically substantiated of fluorite carbonate-bearing ores enrichment effectiveness improvement by raising the enrichment process continuity and stability, diminishing the volume and perseverance of foam produced during flotation; optimal process parameters are worked out that determine collector selective adsorption on fluorite; the modificator that has been found intensifies the process of collector interaction with the mineral surface. The scientific base level is academic. There is a possibility to further enhance the technology and find additional applications to it. “Know-how” is present and rights for it may be transferred. Examples of practical applicationThe technology is being used in mining industry to ensure the effectiveness and safety of mineral raw materials processing. The technology undergone testing, modification, and implementation at concentration plant of Russkaya Gornorudnaya Kompaniya LLC (Primorski Krai, Russia). The Institute brought to commercial level the created technology, which makes it possible to raise the effectiveness and safety standards. There is full usage preparedness. Actual buyers: Russkaya Gornorudnaya Kompaniya LLC and other enterprises engaged in highly carbonaceous ores processing. Sales market geographyMain market segments are enterprises of the Russian Siberian and Far Eastern regions. Planned to realization in the Peoples Republic of China.
