Vedclass · Answer

(B) The method described involves placing finely powdered ore on a rotating grooved table. As the table rotates,the heavier ore particles settle in the grooves,while the lighter gangue (impurities) particles are washed away by a stream of water. This process is known as Gravity Separation or the Wilfley table method,which relies on the difference in densities between the ore and the gangue. Therefore,the correct option is $B$.

When finely powdered ore is placed on a rotating grooved table and rotated rapidly,the lighter impurities are removed. What is this method of concentration called?
