magnetitecontaining
Magnetite-containing, sometimes written magnetite-containing, is a general descriptive term used in geology, materials science, and related disciplines to denote any material that includes magnetite (Fe3O4) as a component. Magnetite is a ferrimagnetic iron oxide with a cubic inverse spinel structure that occurs naturally as the mineral magnetite. In rocks and soils, magnetite can form as a primary magmatic phase or as a product of hydrothermal and metamorphic processes, and it appears as discrete grains, coatings, or disseminated particles.
Materials described as magnetite-containing can range from natural rocks and minerals to engineered composites and concretes
Applications include magnetic separation and dense-medium separation in ore and coal processing, pigments and ceramic glazes,
Geologically, magnetite-bearing rocks preserve remanent magnetization used in paleomagnetism, and magnetite indicates oxidation conditions in rocks
Safety considerations depend on form; natural magnetite is relatively low-toxicity, but inhalable magnetite dust poses inhalation
