2014-1-18 · The sample under study originates from the beneficiation circuit of the Lisakovsk (Kazakhstan) iron ore processing plant and is used as received. It is further denoted in this study as GM (gravity-magnetic) concentrate. Chemical analysis of the concentrate before and after leaching has been done using a sequential XRF XP X-ray spectrometer ARL 9400. For tracking the mineralogical transformations in iron bearing minerals occurring during thermal treatment at the various roasting temperature intervals, different samples have been subjected to X-ray diffraction analysis. In view to accomplish this, a representative sample from the concentrate has been taken by a riffle divider and a 5 % mixture with coke ground to 35 % - 0.425 mm was prepared. The mixture is placed inside five shamot crucibles and heated respectively to 500°C, 600°C, 700°C, 800°C and 900°C for 30 min. The crucibles are covered with steel lids in order to protect the sample
