Outotec’s CarbonSense is a carbon monitoring system designed to minimize gold solution losses from carbon-in-pulp and carbon-in-leach during gold extraction. The CarbonSense system consists of two measurement probes, placed directly in the carbon-containing and carbon-free areas of the slurry tank, which use electrodes to continuously measure carbon levels throughout the tank. “Since the activated carbon increases the slurry’s conductivity, the carbon concentration can be measured in real time by comparing the results from the two probes,” Peter Blanz, product manager of intelligent instruments at Outotec, told CIM Magazine. “This makes the measurement’s frequency and reliability much higher than traditional methods that involve taking a sample of the slurry.” According to Outotec, CarbonSense is fully automatic and easy to maintain.
