Metre monitors concentration of carbon in adsorption tanks

The C2 meter, a self-contained carbon concentration meter which continuously monitors and controls (if required) the concentration of carbon in carbon-in-pulp and carbon-in-leach adsorption tanks, is being used by South African gold mines.

Developed by the De Beers group, the meter is based on the principle that the attenuation of high-frequency, ultrasonic pulses transmitted through the pulp bears a relationship to the concentration of carbon within pulp. This relationship is directly dependent on pulp density. Changes in pulp density affect the degree of attenuation, which results in a change in the carbon concentration value recorded and displayed by the meter.
