2 1 Phosphate occurrences Iron ore of high phosphorus content coexists with other minerals in the form of apatite or fluorapatite Phosphorus is spread on the edge of mineral particles of iron oxide and embedded in quartz or carbonate minerals and a small amount is present in the iron mineral grid (Xia et al 2011) The most frequent and important constituent of the class of phosphates is
Ore deposits that are associated with mafic to ultramafic igneous rocks can generally be divided into those where the metals of interest are hosted in oxide minerals and those where the metals of interest are held as sulfides or are strongly associated with sulfides (e g PGE alloys arsenides bismuthinides) The oxide ore bodies include stratiform podiform and breccia related chromite

Mar 14 2014 The ore is mined from large open pits by progressive extraction along steps or benches The benches provide access to progressively deeper ore as upper level is removed After the soil and overlying rock are cleared the ore is drilled and blasted The portion of the ore body to be removed is first drilled by using rigs in an appropriate pattern
Ore bodies are formed by a variety of geological processes The process of ore formation is called ore genesis Ore Preparation It takes multiple steps to extract the “important” element from the ore First the ore must be separated from unwanted rocks Then the minerals need to be separated out of the ore
