  • Ore pretreatment process EXXON RESEARCH AND

    What is claimed is 1. A method of pretreating a gangue-containing particulate oxidic iron ore to lower the sulfur and phosphorus in the ore which comprises washing a particulate oxidic iron ore consisting essentially of iron oxides and gangue with an aqueous solution of an inorganic base and thereafter washing the ore with water.

  • Sequential soil washing techniques using hydrochloric acid

    Abstract. Sequential washing techniques using single or dual agents sodium hydroxide (NaOH) and hydrochloric acid (HCl) solutions were applied to arsenic-contaminated soils in an abandoned iron-ore mine area. We investigated the best remediation strategies to maximize arsenic removal efficiency for both soils and arsenic-containing washing solution through conducting a series of batch experiments.

  • Production of a ferric chloride coagulant by leaching an

    2020. 9. 1.· Iron ore tailing was used as a raw material for the production of ferric chloride. • Leaching studies were carried out with hydrochloric acid. • Best results were attained with a 10.8 mol L-1 of HCl, a temperature of 80°, and a leaching time of 120 min.. The procedures allowed 94% recovery of iron present in the iron ore tailing.

  • Froth Flotation of Iron Ores

    2012. 1. 2.· With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

  • How to Remove Iron Ore Stains eHow

    2020. 10. 18.· Iron ore -- otherwise known as rust -- is among the most pervasive of stains. It seems to appear like magic on porcelain bathroom and kitchen fixtures, and can leave its imprint behind on fabric and other surfaces as well. If you put an iron object on anything that subsequently gets wet, chances are you will get a rust stain.
