Abstract
In the process of developing deposits of magnetite quartzites, hematite quartzites are simultaneously involved in mining. But the processing of hematite quartzites is associated with significant difficulties, so they accumulate in warehouses, landfills and spread uncontrollably in the environment. A detailed study of the features of the composition, structure and technological properties of hematite ores made it possible to develop a new method for complex processing in a vortex air-mineral flow. Under laboratory conditions, a number of commercial products were produced from them: iron ore concentrate, sinter ore, clinker ore, mineral paint and quartz sand, without waste accumulation. The formation of magnetic floccules is reduced in the air stream. Therefore, this technology also improves the processing of magnetite ores.
