Rehabilitating Tailings Dams
CBNC and THPAL produce intermediates for electrolytic nickel and nickel sulfate. At tailings dams, the slurry after the recovery of
nickel through the production process is treated through neutralization to eliminate toxins and precipitate heavy metals. The
treated slurry is then pumped to the tailings dam where it allows the solids to settle down.
When the storage capacity of the tailings dams is reached, the site is rehabilitated in order to establish an independent and sustainable
ecosystem. Rehabilitation does not simply mean greening, but also making it possible for the area to return into its original
state which is conducive to sustaining a natural ecosystem. This involves agroforest technology wherein the forest is established
alongside agricultural farming. Thus, vegetables and fruits are also grown in the area. Many local residents and indigenous people
are involved in this work, and rehabilitation plays an important role in creating local employment.
