Mine tailings' size and composition depends on the mining method. For hardrock metal mines, tailings are usually a very fine mud or powder, which is left over after ore is crushed and valuable minerals are extracted from it. Tailings may also contain chemicals used for mineral extraction.

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
