Abstract

This article intends to show efficiency of research using computer technologies and chemical programs. The flotation activity of flotation reagents of a new class was studied. Molecular modelling of the modified reagents was performed applying computer parametres. Flotation tests were carried out on calcite, barite, celestine, fluorite and quartz. The reagents under study were tested at flotation of various fluorite ores. To optimize the flotation of the fluorite ores, combinations of reagents were used. The tests showed that a combination of reagents at such flotation of fluorite ores would contribute to production of a fluorite concentrate with the CaF2 mass fraction of 96.3 %, at extraction - CaF2 of 85.4 %.

Keywords
