    In the present study, the use of horse residue as an alternative reducing agent in the roasting of a lowgrade goethite ore containing % Fe was investigated. Additional roasting experiments were carried out with corn starch and without reducing agent for comparison. Each roasted product was characterized using Xray diffraction (XRD) and magnetic hysteresis (MH) loops analyses.

  • Goethite: The mineral goethite information and pictures

    Goethite is a common mineral, and is a frequent matrix material for other more aesthetic minerals. It is usually a dark, uninteresting mineral, though specimens from a handful of locations (especially Colorado) are remarkable for their delicate and beautiful crystal growths and velvety botryoidal growths. Goethite is also frequent as black crystal sprays that form within geodes on drusy Quartz.
