The equipment used during the bauxite mining process has evolved over the years. During the earlier year's pickaxes, spades, hand shovels and wheel barrows were used in the bauxite mining process, however over the years these tools were replaced by highly mechanised equipment which resulted in increased production and productivity.

Sustainable bauxite mining is not a "one-size fits all" prescriptive process but involves risk management and applying technologies appropriate to the circumstances of each mine. These Guidelines build on the 2018 Sustainable Bauxite Mining Guidelines (SBMG) and provide a practical, attainable guide to improve sustainability.
