At our mine-sites in South Africa and Australia, Tronox puts back what we don’t use. Our rehabilitation efforts stem from a deep-seated appreciation for the richness of the land where we operate and the value that it represents to our communities.
During mineral excavation, the top soil and native plants are carefully removed and preserved. Roughly 5-10 percent of the soil harvested from our mines is useable ore, while the rest of the soil is returned and the landscape is restored to its natural form. The area is rehabilitated with the original top soil and either native flora is replanted, or the site is used by local farmers for cash-generating agricultural crops. Tronox also partners with external organizations to promote biodiversity. At KZN Sands, for example, the company partnered with the University of Zululand and the South African Sugar Research Institute (SASRI) to research factors affecting sugarcane yield in rehabilitated soils, and also partnered with Paperbark Forestry Consulting to research Eucalyptus growth and mortality in rehabilitated soils. And in Western Australia, Tronox teamed with Murdoch University to research soil microbial activity in rehabilitated areas and baseline reference sites. The study’s outcomes are anticipated to yield improvements in the diversity and abundance of vegetation in rehabilitation.
