2021-2-21  The process of open-pit mining is precipitated by the analysis of the area in order to determine the presence of the desired material that may be coal or ore. If it is determined that the desired materials are present in the area, the next step would be to calculate the stripping ratio of the mining process, meaning that even though ore, coal

Rehabilitation Process Developed Over 35 Years The Huntly bauxite open pit is continually being rehabilitated as mining continues at the site. When an area becomes mined out and the haulage roads are no longer required to take mined ore from the pit in that area, work starts on re-establishing a self sustaining jarrah forest ecosystem.
