Detailed studies of the limestone deposit and the stone itself are required for intelligent beneficiation. As used in this paper, beneficiation is defined as the improving of limestone composition so as to produce an economically usable raw material. A limestone deposit is defined as a mass of limestone which can be recovered, by quarrying or

The economic deposits of cassiterite are known in two types of geological occurrences – primary vein or hard-rock deposits and secondary placer deposits (Falcon, 1982, Rao, 1992). The mineral assays about 0.4–1.5% Sn (occasionally 5–6%) in the hard-rock deposits and placer deposits are slightly poorer in grades ( Bulatovic, 2010 ).

The X-ray diffraction pattern of BHQ ore and the quartz particles derived after removal of iron by acid leaching of the ore is shown in Fig. 2. The diffraction pattern matches well with the standard powder diffraction pattern of hema-tite and quartz phases. It can be seen that hematite and quartz are the major mineral phases present in the BHQ ore.
