Iron is present in significant concentrations in bauxite residue, particularly in high‑iron bauxite residue produced by the Bayer process, which contains over 30 % Fe 2 O 3. The primary iron-containing minerals are hematite, with smaller amounts of goethite, ilmenite, and other minerals ( Borra et al., 2016b ; Liu et al., 2021 ).
Bauxite dust also displaced monkeys from Bukit Goh's oil palm plantations, which encompasses nearly 69% of the community's land area. The animals have fled to residential areas, Jehan said. "When plantations started to be cleared for bauxite mining, they moved to where they can find food," Jehan said.
The top image is Google Earth satellite imagery from December 1996, and the bottom is from December 2016. What was a relatively centralized mining operation in 1996 has since expanded to create a broader network of mining zones connected by unpaved roads. Bauxite dust can be identified via its characteristic neon-red hue.
