PRE LAB REPORT 4: DETERMINATION OF FE IN IRON ORE Course : CH-207-106 Instructor : Gillian L Goring Introduction Iron ores are rich in minerals and rocks: from this metallic iron is extracted for economical purposes. There are five main types of ores of iron: hematite, limonite, goethite, siderite, and magnetite. Magnetite (72%) is highly rich in oxide out of all classes.
Ore Reserve Estimation Method
Ore-reserve estimates include the determination of (1) tonnages of ore and (2) average grade or value per ton. Since the grade or content of valuable metal establishes the difference between rock that may and may not be classed as ore, tonnage cannot be estimated without considering the question of grade.
