Abstract:

point of view. In this study, a shaking-table was used for concentrating a manganese ore sample from the Ghasem Abad

area in Kerman, Iran. Experiments were designed by using L

The influence of each variable and their interactions on the operation of the device was studied. The variables under

investigation were: table slope, table frequency, water flowrate, feed rate, and particle size. The manganese

concentrate grade, recovery, and separation efficiency were used as response variables. It was shown that water

flowrate, table slope, feed rate, and particle size are the significant variable on concentrate grade while, all the

variables influence manganese recovery. Also, water flowrate, table slope, and table frequency have an important

effect on manganese separation efficiency. Finally, three mathematical models were presented to predict the values of

each response variables.
