Easy Guide to Mining Waste Characterisation

Waste characterisation is the study of the environmental impacts of mining waste during mining, processing and above ground storage of ore prior to treatment. Waste characterisation needs to consider whether the waste will cause: acid metalliferous drainage (AMD) saline and/or sodic drainage (i.e. neutral mine drainage) leaching and mobilisation of metals and toxic compound Get price
