The overall objective of this article is to study the potential of the reagent treatment of wastewater resulting from the iron ore beneficiation process, as well as preventing the discharge of the wastewater into the open waters. The wastewater at the Mikhailovskii iron ore beneficiation plant (Kursk Region, Russia) discharged into a tailings pond has become an object of the research.

Abstract. The effectiveness of jigging operation for the beneficiation of low-grade iron ore deposits of Orissa, India has been investigated. Iron ore sample obtained from Barbil region of Orissa containing very high amount of silica and alumina was crushed using the laboratory jaw crusher and roll crusher to prepare different particle sizes.
