Selection of Tailings Site of Gol-e-Gohar Iron Ore Processing Plant Using the Modified TOPSIS Method
Multiple Attribute Decision Making (MADM) method is applied to select tailings site of the Gol-e-Gohar Iron Ore Processing Plant in the Kerman province,south-eastern of Iran.To select tailings site,screening is applied on eight location proposed by Binnie and Granges.Consequently three sites identified for further studies.Evaluation factors include only the most important factors such as efficiency ratio,elevation and distance to processing facilities,occurrence of faults and fractures.Crisp values such as efficiency ratio,elevation and distance can be determined by measurements and calculations,but some factors such as occurrence of faults and fractures are presented as linguistic values that can be described with triangular fuzzy numbers.Based on evaluation values obtained an optimal tailings site can be selected using a modified Technique of ranking Preferences by Similarity to the Ideal Solution (TOPSIS) given crisp data and linguistic variables as the alternatives of attributes.Each attributes weight is assigned using the analytic hierarchy process.The final ranking order aids in the selection of tailings site.Finally,the stages of modified TOPSIS method were applied and site No.2 situated in 5400m to the mill was selected as the best alternative.
