Abstract: 

In this research, column flotation tests have been conducted in three phases, by employing a column with 200 Cm height and 9 Cm diameter. Also conventional flotation tests were conducted using a Denver model conventional flotation machine. Molybdenite concentrate was obtained from rougher stage feed in Sarcheshmeh copper refinery. Obtained results from column and conventional cell were compared.
The optimum conditions were found to be QF=60 l/h, Qa= 100 l/h, QW=70 l/h and QT= 120 l/h. The pulp density, sodium sulfide content and pH, were 15% ,8 kg/t and 12, respectively. Under this condition, 92% of molybdenum was recovered while the grade of molybdenum was 3.9% .The separation efficiency of the process was calculated to be 69%. The recovery and grade of molybdenum by using conventional flotation machine were found to be 84% and 4% respectively. Separation efficiency with pH of 12, pulp density of 15% and 8 kg/t sodium sulfide was calculated to be 64%. The result from column flotation showed that molybdenum recovery and separation efficiency can be increased 8 and 5 percent respectively in comprised to the results from conventional flotation.
