Rodinia Resources has developed its own unique technology for the bio-rehabilitation of mineral tailings stored in dams and other impoundments to produce an engineered soil thereby potentially freeing land for more valuable uses


Rodinia Resources’ technology has the potential to process the entire volume of mine or refinery tailings, compared to the current practice of only rehabilitating the top 1-2 metres, known as “capping”. Rodinia’s process aims to completely removal of environmental liabilities such as the contamination of water within 10-20 years of a mine closure.

In addition, the Rodinia process uses waste from other industries as reagents, thereby addressing two environmental issues at the same time.

The complete removal of tailings can make the land available for more valuable uses, compared with conventional capping, where at best the land may be only usable for native vegetation.


Using locally available Biomass and natural microbes we begin the process of regenerating Red Muds into engineered soil – TECHNOSOL.

The waste from alumina refining (commonly called ‘red mud’) is neutralised and cured in a two step process that eventually will enable once contaminated tailings to be used as engineered soil.

After the red mud is neutralised, it is cured for three months and placed in a stockpile prior to planting with pioneer crops. Resilient plants such as sorghum and alfalfa are grown over the course of a year and leach sodium out of the soil as well as immobilizing heavy metals. Once the pioneer crop process is finished, the soil may then be useable as a proxy for agricultural soil.


The entire RODINIA Process is to take months to years rather than traditional and current industry processes that take decades with ongoing leaching lasting 100+ years.
