1. In an ore you are undertaking testwork on for RL Mining Ltd, mineralogical analyses show that it has equal amounts (by mass) of the minerals shown in Table 1, and no others. ‘Table 1: Minerals and some properties Mineral Formula Relative Electrostatic | Magnetic Density limenite FeTiO, 4.70- Thrown Yes 4.79 (para) Magnetite | FeO, ~52 Thrown Strong (ferro) Monazite (Ce, La, Pr,Nd, Th, | 4657 Pinned Yes Y)PO, (para) Zircon zrsio, 46-47 Pinned No (dia) Quartz sio, 2.65 Pinned No (dia) You have access in the lab to a low intensity magnetic separator (LIMS), a wet high intensity magnetic separator (WHIMS), a Multi-Gravity Separator (MGS) and an electrostatic separator. Previous testwork on the recovery of each mineral in the various separators to be as detailed in Table 2. Based upon this, and using a flowsheet that you propose, what is the mineral grade and recovery in each concentrate stream? In this deposit, value can be found from each mineral if the grade and recovery justify the cost (but that is not part of this question). Include a block diagram of the flowsheet you are following. Show sufficient calculations that the Grader can follow your work, and upload both a Word/pdf file of your written answers and the Excel spreadsheet if you used Excel for the calculations.
