Abstract

It is well known that the variations in temperature, chemical reactivity, and reaction rates which are presumed to occur and which in some cases have been shown to occur in a leach dump or similar solution mining activity are difficult to duplicate or model on a small laboratory scale, and the degree to which such large-size metallurgical processes can be scaled is not well established. In the present investigations the design criteria and sampling methods for large-scale leach tests on low-grade copper waste are outlined and the results of studies of temperature profiles and associated chemical and biological activity in 185 ton waste samples (approx. 10. 75 m in height) are discussed. Various simple scaling features are presented, including drain-down characteristics and waste-body neutralization.
