  • Laboratory Concentrating Table consists of a slightly inclined deck on to which feed, bout 25% solids by weight, is introduced at the feed box and is distributed along the feed launder, wash water is distributed along the balance length of the feed launder. The table is given shaking motion longitudinally using a slow forward stoke and a rapid return, which causes the mineral particles to move along the deck parallel to the direction of motion. In this table the riffles run parallel with the long axis and are tapered form the maximum height on the feed side till they die out near the opposite side, parts of which is left smooth.

    Laboratory Floatation Cell is the most important single mineral concentrating operation. It is also the most efficient, most complicated, most sensitive, most challenging and least understood mineral processing operation today. The art of flotation has been correctly called the most impressive wide-scale technical application of classical surface chemistry. Only in the last three decades has much progress been made in understanding its mechanisms.
