Preliminary feasibility study of the Qara-Aghaj titamium deposit, Orumiyeh
The Qara-Aghaj titanium deposit is located 36 Km away from the NW of Orumiyeh. The deposit was studied in several systematic projects by the Kawoshgaran Consulting Engineers. In the last step, after preparing geological and geophysical maps by surface and subsurface data, four samples were prepared for ore dressing studies.
This report presents the result of feasibility study on the deposit. At firstm based on the previous studies we selected the suitable block for mining. The geological reserve of this block is about 25 million tons ore of 9.45% TiO2. Based on the comparative method, the selected annual production capacity is 50000 tons concentrate that requires 820000 tons ore per year. The mining method is open-pit. Based on the conceptual design, the exploitable reserve is 16.8 million tons and gangue material is 9 million tons.
The estimation of production cost per ton of ore material was made by two approaches:
1- on-time costs of main machineries that can be provided in the region
2- costs of new machines released from factory
Details of cost estimation included in the report.
