Outotec USA Inc Minerals Processing Physical Separation Magnetic separation equipment has long been used to upgrade and beneficiate a wide variety of minerals and materials Over the years significant advances in both wet and dry magnetic separators have improved their operability and separation performances broadening their use
Magnetite apatite ore deposits are interpreted as being formed by the crystallization of iron rich ultrabasic melts dominantly generated by the interaction of silicate melts with oxidized P F SO4 bearing sedimentary rocks This hypothesis is supported by geologic evidence experimental studies numerical modeling stable and radiogenic isotope
In nature the iron in the mineral is often substituted by cobalt antimony and nickel The presence of these elements distorts the structure of the pure mineral which complicates the understanding of its magnetic behaviour For effective separation of some minerals using electrostatic means the usual practice is to impose an electric field

7 Adsorption adhesion of atoms ions or molecules of gas liquid or dissolved solids to a surface Centrifugation and cyclonic separation separates based on density differences Chromatography separates dissolved substances by different interaction with travel through a material Crystallization Decantation Demister vapor removes liquid droplets from gas
2 INTRODUCTION Iron atomic weight is essential for many metabolic processes It shares with other transition metals two properties of particular importance in biology the ability to exist in more than one relatively stable oxidation state and the ability to form many complexes Its ability to exist in both ferric and ferrous states underlies its role in critical
Iron titaniferous sands also called black sands are a source of various magnetic minerals such as iron and titanium Fe Ti oxides with countless scientific and industrial applications Ecuador is deemed a geo diverse country that contains deposits of black sands in the Andean and coastal regions; therefore the industrialization of these magnetic
Upgrading iron ore fines 10micron to 1mm Recovery of fine iron ore from tailing streams Separation of ilmenite from heavy mineral sand concentrates to reduce downstream processing Removal of magnetic contaminants from slurried materials eg cassiterite kaolin silica etc

It is a hot topic to recover iron from red mud in the research field of solid waste comprehensive utilization but high quality iron concentrate is always difficult to be obtained unless by high temperature reduction roasting magnetic separation In this study low temperature magnetization roasting magnetic separation has been conducted to recover iron
Magnetic separation has two major applications in mineral processing plants The removal of tramp iron which would deleteriously affect subsequent processes from an ore stream This is usually achieved by a low intensity magnet suspended above or at the head of a conveyor Separation of magnetic minerals from less magnetic minerals
In the iron ore beneficiation process high intensity magnetic separation is used for minerals with low magnetic susceptibility while lowintensity magnetic separation is used for minerals with
ABSTRACT Comprehensive utilization of tailings resources not only solves environmental problems but also creates huge economic benefits In this paper fine weakly magnetic particles were extracted from iron ore beneficiation tailings and silica SiO 2 was separated and purified using a superconducting high gradient magnetic on
