By investigating the process of erosion on the jams it should be possible to predict rates of erosion and hence formulate ways of controlling the loss. The Chamber of Mines has developed a device for

The effects of oxygen flow rate and solution temperature on the decopperization of anode slimes were examined in H 2 SO 4 medium and copper recovery was achieved with an efficiency of 94%.

Fine-grained, sulphidic, tailings impoundments generate ARD through the diffusive ingress of oxygen into

Supervision of construction or reconstruction of the dam by a licensed professional engineer is required to insure that the dam will be built according to the approved plans.
