QEMSCAN Analysis of Wadi-Shatti Iron Ore (Libya)

Abstract

Libyan Iron ores reserve estimated to be > 5.0 billion tons, with 48–55% Fe& 1.0% P& Libyan Previous detailed investigation by FSG& IRC was not sufficient& did not adopt any technology to remove P), (Si) & alkaline. Due to price increasing of iron ores in global markets, gave potentials to treat high (P) iron ores in economical ways. Recent global treatment of high (p) iron ores results may be adopted to treat the Libyan ores & the predication may be fruitful. A Preliminary QEMSCAN analysis of Libyan iron ores samples was conducted at(advanced mineralogy research center- CSM), to determine, phosphorous phases, locking and liberation characteristics of the phosphorous phases and mineral associations. Determination shows that 61 % Fe as Oxide/Hydroxide, 31 % quartz, 5 % apatite, and other traces. Fe occurs in fraction 300/+150 µm. Highest concentrations of apatite occur in the coarsest fraction assay shows 1.0 % P and 39 % Fe & most of Fe found in coarsest size fraction. Size fractions of P < 0.5 mass %& elemental deportment of (P) is present in apatite, in fraction 75 µm &0.3 mass % P occur in monazite 68 % of apatite is liberated; the majority of liberated apatite 62 % can be observed in the 75 µm fraction. The fruitful findings may give an excellent encouragement to perform preliminary floatation& leaching experiments as long as the phosphorous existed as apatite phase& it can be separated by many different promising techniques as well.
