An enthusiastic decarbonisation activity in Phalaborwa intends to attract out helpful uncommon planet steels whereas on the identical time restoring a setting harmed by years of phosphoric acid manufacturing.
Located 5 minutes from the Phalaborwa most important downtown close to the boundary of the Kruger National Park, the duty will definitely draw out uncommon planet steels made use of within the manufacture {of electrical} vehicles and wind turbines from stacks of phosphogypsum– a spin-off of phosphoric acid.
According to the agency, Rainbow Rare Earths, these steels will definitely play an important obligation within the environment-friendly financial scenario. Rainbow intends to make as much as 98% of the whole worldwide uncommon planet market by 2030, putting it as a big gamer within the uncommon earths-driven decarbonisation activity.
“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,” acknowledged ceoGeorge Bennett “Phalaborwa remains the highest-margin rare earth project in development today outside of China.”
The predicted web price of the Phalaborwa activity stood at US$ 611-million since December 2024, with the London Stock Exchange- famous agency preserving in thoughts that the duty has diminished working expense and higher margins than comparable duties past China.
Rainbow invested regarding $15.7-million in between 2020 and 2022 on acquiring an 85% ardour within the activity and offering an preliminary monetary analysis. A transparent-cut expediency analysis from 2024 to 2025 expense regarding $4.8-million.
Rainbow is predicting that the constructing and building stage will definitely set you again regarding $326.1 million in between 2026 and 2027, which manufacturing will definitely start within the final quarter of 2027.
Environmental restoration
According to Bennett, the duty’s dedication to restoration and minimizing the eco-friendly damages triggered by earlier mining procedures is an important high precedence.
The restoration process is anticipated to develop as a lot as 300 duties, profiting licensed regional residents all through the anticipated 16-year life expectancy of the removing process and previous, in keeping with the agency’s preliminary monetary analysis, with the land being made use of ideally for as a lot as 40 years.
The ecological damages on the web site may be mapped again to 1964, when it was had by Federale Volksbelegging, a enterprise that created phosphate-based fertilizer. Sasol took management of procedures in between 2001 and 2012, complied with by Bosveld Phosphates up till 2014. In 2020, a proposal was approved in between Rainbow and Bosveld Phosphate to attract out the bizarre planet steels.
The stage of the ecological damages triggered by on the very least 6 years of mining is appreciable. Bennett acknowledged that because of the absence of insurance policies regulating mining duties on the time, the heaps of phosphogypsum weren’t lined, inflicting groundwater contamination.

International ideas
“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 acknowledged.
The ideas are utilized by banks to acknowledge, look at and deal with the ecological and social risks of a job, and the requirements are made use of by the World Bank Group to assist clients like Rainbow to protect the ambiance and attain their creating affect aims.
“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 mentioned. “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 restoration possible?
Mining duties usually adversely have an effect on the ambiance and bordering areas, triggering logging, grime disintegration, polluted water our bodies (rivers, dams, lakes, and groundwater), boosted sound levels and grime.
A two-year investigation by Oxpeckers from 2015 to 2017 revealed that actually couple of enterprise shut huge mines, which the money they’re lawfully required to order for ecological restoration is usually little or no.
For a water-scarce nation like South Africa, falling brief to repair up mines which have really reached their finish of life leaves people, pets and vegetation prone to consuming polluted water from acid mine water drainage.
The Phalaborwa activity, which operates an current industrial web site with out calling for added excavation, intends to make sure that restoration occurs along with removing.
Alseno Mosai, a speaker and scientist within the Department of Chemistry on the University of Pretoria, acknowledged such restoration is possible and has really been successfully taken on by varied different mining enterprise 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 acknowledged.

Economic utilization
“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 acknowledged.
Mosai included that this restoration typically consists of using a earlier mining location for duties similar to preservation.
Rainbow prepares to make the most of the restoration process in Phalaborwa to revitalize the monetary use the staying phosphogypsum on web site by advertising and marketing it to the farming trade and varied different sectors. The agency anticipates roughly 2.2-million tonnes of phosphogypsum will definitely be refined a yr.
“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,” acknowledged Bennett.
Bennett cannot reveal simply how a lot money had really been reserved for the restoration activity.

Critical minerals technique
Mintek is main the answer of an important minerals technique for South Africa that may placed on the removing of the form of steels and oxides Rainbow intends to take away: 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,” acknowledged DMRE consultant Makhosonke Buthelezi.
Asked whether or not there are numerous different duties in South Africa similar to Phalaborwa uncommon 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 tackle on the yearly Mining Indaba on February 3 in Cape Town, Minister of Mineral and Petroleum Resources Gwede Mantashe acknowledged a nationwide vital minerals technique requires to think about 5 key requirements: export worth, regional monetary affect, industrial relevance, work and worldwide market want.
“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 acknowledged.
According to Mantashe, the tactic will definitely exist to Parliament on the finish of February.

Community benefits
While the duty provides activity prospects for Phalaborwa locals, worries linger in regards to the truthful circulation of those benefits.
“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, aged scientist on 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 manager supervisor of Oxfam South Africa, acknowledged regional areas are usually omitted from settlements, leaving them prone to exploitation by mining enterprise. She harassed the requirement for important space possession in duties just like the Phalaborwa uncommon 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,” acknowledged Ramafoko.
Tomaselli included {that a} sturdy vital minerals technique must protect the correct to say no, together with assurance complimentary, earlier and enlightened permission for mining-affected areas. Currently the Minerals Petroleum Resources Development Act simply acknowledges areas’ civil liberties to examination and doesn’t protect permission.
“This lower requirement leads to disempowerment and exploitation,” Tomaselli included.
