An enthusiastic decarbonisation task in Phalaborwa intends to draw out beneficial unusual planet steels while at the same time restoring a setting harmed by years of phosphoric acid manufacturing.
Located 5 mins from the Phalaborwa main downtown near the boundary of the Kruger National Park, the task will certainly draw out unusual planet steels made use of in the manufacture of electrical cars and wind generators from stacks of phosphogypsum– a spin-off of phosphoric acid.
According to the firm, Rainbow Rare Earths, these steels will certainly play a vital duty in the environment-friendly economic situation. Rainbow intends to make up to 98% of the complete international unusual planet market by 2030, placing it as a significant gamer in the unusual earths-driven decarbonisation task.
“Delivering on our plans will make South Africa one of the first producers of separated rare earth oxides outside of Asia, giving the country a strategic role in the development of an independent and diversified supply chain for critical rare earths,” stated ceoGeorge Bennett “Phalaborwa remains the highest-margin rare earth project in development today outside of China.”
The predicted internet worth of the Phalaborwa task stood at US$ 611-million since December 2024, with the London Stock Exchange- noted firm keeping in mind that the task has reduced operating expense and greater margins than comparable tasks beyond China.
Rainbow invested concerning $15.7-million in between 2020 and 2022 on obtaining an 85% passion in the task and providing an initial financial evaluation. A clear-cut expediency research from 2024 to 2025 expense concerning $4.8-million.
Rainbow is predicting that the building and construction stage will certainly set you back concerning $326.1 million in between 2026 and 2027, which manufacturing will certainly begin in the last quarter of 2027.
Environmental recovery
According to Bennett, the task’s dedication to recovery and minimizing the eco-friendly damages triggered by previous mining procedures is an essential top priority.
The recovery procedure is anticipated to develop as much as 300 tasks, profiting certified regional citizens throughout the predicted 16-year life expectancy of the removal procedure and past, according to the firm’s initial financial evaluation, with the land being made use of ideally for as much as 40 years.
The ecological damages at the website can be mapped back to 1964, when it was had by Federale Volksbelegging, a business that created phosphate-based fertilizer. Sasol took control of procedures in between 2001 and 2012, complied with by Bosveld Phosphates up until 2014. In 2020, an offer was authorized in between Rainbow and Bosveld Phosphate to draw out the unusual planet steels.
The level of the ecological damages triggered by at the very least 6 years of mining is considerable. Bennett stated that as a result of the absence of policies regulating mining tasks at the time, the heaps of phosphogypsum were not lined, causing groundwater contamination.

International concepts
“Rainbow will be reprocessing the gypsum stacks, extracting the rare earths and then re-stacking the clean gypsum by-product on to new stacks that have been designed and lined in accordance with the Equator Principles and International Financial Corporation guidelines,” he stated.
The concepts are used by banks to recognize, examine and handle the ecological and social dangers of a job, and the standards are made use of by the World Bank Group to help customers like Rainbow to shield the atmosphere and attain their developing influence objectives.
“We will also neutralise the acidic water that has accumulated on top of the existing stacks and use this to meet the water requirements of our processing plant, thereby negating the need to draw on an external water source,” Bennett discussed. “The clean gypsum by-product will be sold to local agricultural and other industries over time, meaning that the stacks will eventually be depleted, allowing the land to be fully rehabilitated.”

Is recovery feasible?
Mining tasks typically adversely affect the atmosphere and bordering areas, triggering logging, dirt disintegration, polluted water bodies (rivers, dams, lakes, and groundwater), boosted sound degrees and dirt.
A two-year investigation by Oxpeckers from 2015 to 2017 revealed that really couple of business close massive mines, which the cash they are lawfully required to reserve for ecological recovery is typically very little.
For a water-scarce nation like South Africa, falling short to fix up mines that have actually reached their end of life leaves individuals, pets and plants susceptible to eating polluted water from acid mine water drainage.
The Phalaborwa task, which operates an existing commercial website without calling for added excavation, intends to make certain that recovery happens together with removal.
Alseno Mosai, a speaker and scientist in the Department of Chemistry at the University of Pretoria, stated such recovery is feasible and has actually been effectively taken on by various other mining business in South Africa.
“Previously mined areas can be rehabilitated and returned close to the quality that they had before the mining, or to a safe and a stable condition,” Mosai stated.

Economic usage
“Mintek, South Africa’s national mineral research organisation, in partnership with the Department of Mineral Resources and Energy has rehabilitated more than 40 abandoned and derelict asbestos mine shafts in the Northern Cape and Limpopo provinces. As a result, Mintek has rehabilitated over 500ha of asbestos mines,” he stated.
Mosai included that this recovery often consists of utilizing a previous mining location for tasks such as preservation.
Rainbow prepares to utilize the recovery procedure in Phalaborwa to revitalize the financial use the staying phosphogypsum on website by marketing it to the farming industry and various other sectors. The firm anticipates approximately 2.2-million tonnes of phosphogypsum will certainly be refined a year.
“We will look to employ local skilled labour where possible. We believe there to be good availability of technical skills locally given that Phalaborwa is a long-term mining district with a number of historic and current operations in the area,” stated Bennett.
Bennett can not reveal just how much cash had actually been reserved for the recovery task.

Critical minerals method
Mintek is leading the solution of an essential minerals method for South Africa that will put on the removal of the kind of steels and oxides Rainbow intends to remove: neodymium, praseodymium, dysprosium and terbium.
“The department is consulting with various stakeholders on the strategy, and thereafter the strategy will be presented to Cabinet for approval,” stated DMRE representative Makhosonke Buthelezi.
Asked whether there are various other tasks in South Africa comparable to Phalaborwa unusual planets one, Buthlelezi reacted: “We would not be aware of extraction projects of a similar nature since they do not involve mining minerals from the ground. In such cases, they would not require a mining right or permit.”
During his keynote address at the yearly Mining Indaba on February 3 in Cape Town, Minister of Mineral and Petroleum Resources Gwede Mantashe stated a nationwide important minerals method requires to consider 5 key standards: export value, regional financial influence, commercial relevance, work and international market need.
“This is informed by our firm view that critical minerals should not be limited to the energy transition. Instead, they must facilitate developmental and sustainability objectives within domestic and international industrial sectors,” he stated.
According to Mantashe, the method will certainly exist to Parliament at the end of February.

Community advantages
While the task supplies task possibilities for Phalaborwa locals, worries linger concerning the fair circulation of these advantages.
“Without substantial reforms and a shift toward a more just and sustainable economic framework, mining will continue to serve the interests of corporations and global markets rather than the needs of local communities,” commented Charlize Tomaselli, elderly scientist at the Alternative Information and Development Centre.
“Under the current extractivist model, the likelihood of rare earth minerals directly benefiting the majority of South Africans remains slim.”

Meaningful possession
Lebogang Ramafoko, the executive supervisor of Oxfam South Africa, stated regional areas are typically omitted from settlements, leaving them susceptible to exploitation by mining business. She stressed the requirement for significant area possession in tasks like the Phalaborwa unusual earths endeavor.
“We need a radical approach that creates sustainability and meaningful change. This must include women and youths at the negotiating table because our recent research shows that the energy crisis is a gendered one and the just transition cannot happen without us applying a feminist lens to the crisis,” stated Ramafoko.
Tomaselli included that a durable important minerals method need to preserve the right to claim no, along with assurance complimentary, previous and enlightened permission for mining-affected areas. Currently the Minerals Petroleum Resources Development Act just acknowledges areas’ civil liberties to examination and does not preserve permission.
“This lower requirement leads to disempowerment and exploitation,” Tomaselli included.
