Abstract
A jigging machine for treating minerals has a jigging tank with a jigging container and an air chamber. The jigging tank contains water. The air chamber has at least one inlet valve and at least one outlet valve. A compressed air supply is connected to the at least one inlet valve. Compressed air is pulsed via the at least one inlet valve into the air chamber for forcing the water contained in the jigging tank from the air chamber into the jigging container and, after each pulse of compressed air, the water flows back into the air chamber and forces the air out of the air chamber via the at least one outlet valve. The air chamber has an outlet opening positioned below the lowest permissible water level occurring during a jigging pulse. This outlet opening is constantly open during operation of the jigging machine.
