The mining industry is an important industry in South Africa. It involves a number of industries working together. Exploration is followed by excavation, which is followed by crushing and milling to reduce the size of the rocks. This is followed by extraction (removing the valuable minerals from the ore) and finally refining.
By SCA Community Engagement Fellow Hayden Sloan. Aluminum (or Aluminium, if you're not from the US) is an abundant element within Earth's surface— but getting it out of the ground is an arduous process, requiring heavy machinery to plow up acres and acres of land.Fortunately, the environmental impact of that process can be somewhat balanced out by …
