Laboratory Tumbler

MPC’s laboratory tumbler has been designed and built for simple and efficient operation. Power requirements are 415VAC, 50HZ. 10A. Suitable for a 0.37kw 3 phase motor.

Each tumbler has a 60 x 1L jar capacity. The 60 jars are held in place in 4 plastic tote trays each with a capacity of 15 jars.

Each side of the tumbler holds two such tote trays. The two tote trays are held in place by the locking arm, which is in turn secured by a small “R” clip.

The tumbler will only operate when the front door is closed.

Load the tumbler one side at a time. When the first side is loaded and secured, close the door and press the green start button and wait for the carousel to turn. Press the red stop button when the carousel is in position to unload/load the other side.

Tumbling is preferred to rolling bottle agitation for cyanide leaching because it is more active. This allows for more efficient and faster leaching.

Assay Tabs

AssayPowder is a specially formulated powdered form of AssayTab for laboratory use with bottle rolls and tumblers. This product eliminates the need for double handling reagents since measured amounts can be added directly to the bottle or jar. Technicians can easily tailor their additions to meet test work requirements.

LeachWELL 60X

LeachWELL 60X

LeachWELL 60X is a reagent grade catalyst formulated for fast cyanide leach gold assaying. When used with 5% cyanide the dissolution rate of gold, copper and silver is increased more than sixty fold. The leach rate for gold under appropriate conditions for example, is approximately 1 micron per minute!



DTOX is a waste water treatment product that precipitates heavy metal ions and neutralises cyanide. DTOX reacts quickly with free and complex cyanides. The end products are ultimately released to the environment as carbonates and ammonia (beneficial to flora). Test work has shown that the reaction is rapid and much safer than hypochlorite.
