utilization of high-phosphorus iron ore resources. INTRODUCTION To deal with the contradiction between the con-tinuous depletion of and increasing demand of high-grade iron ore resources in the ironmaking indus-try, efﬁcient utilization of low-grade iron ores and
The iron and phosphorus relationship in the iron and phosphorite ores in Egypt is examined through previously published data. Although Fe- and P-rich sedimentary deposits are closely associated in the same geographic and geological setting in Egypt, no correlation is observed in the examined rocks between iron and phosphorus.
The ore minerals in silicate iron ores are iron chlorites, usually accompanied by hydrous ferric oxides, and sometimes by siderite (25–40 percent iron). There is a negligible content of sulfur and up to 0.9–1.0 percent phosphorus.

Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series.It is by mass the most common element on Earth, forming much of Earth's outer and inner core.It is the fourth most common element in the Earth's crust.Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where it ...
Phosphate salts are retrieved from naturally occurring minerals, which are mined, refined, and purified for use in many applications. Phosphoric acid is produced starting with naturally-occurring phosphate ore mined around the world.
Vivianite is a secondary mineral found in a number of geologic environments: The oxidation zone of metal ore deposits, in granite pegmatites containing phosphate minerals, in clays and glauconitic sediments, and in recent alluvial deposits replacing organic material such as peat, lignite, bog iron ores and forest soils (All).
