Cominco Engineering Services Ltd - sparging.

We had a large plexi-glass tank made. It was then filled with water. At one end, there was a compressing collar – that we could insert various types of pipe.

The pipe end outside the tank – was then connected to an air hose. Each pipe had a unique design – that could produce different types of bubbles.


Cominco Engineering Services Ltd - research.

There are certain types of mining operations where the desired material could be made to float to the top of the processing tank – then slimmed off. In this laboratory test, various factors are studied to see which combination produces the best result.
