Elixir Minerals' supply chain originates in South Africa and is built around the integrated production infrastructure of our established South African production partner — an operation with over 50 years of mineral extraction and processing heritage.
Limpopo Province is not simply where our minerals come from — it is a geological environment that makes them what they are.
Situated in South Africa's far north, Limpopo is one of the country's most resource-rich provinces, and its contribution to both the domestic and global mining sector is substantial and long-established. The province sits atop one of the oldest geological formations on Earth — ancient Precambrian basement rock that has been folded, intruded and mineralised over billions of years into the pegmatite bodies that define the region's industrial mineral identity.
Pegmatite rock is not common. Its formation requires very specific conditions — slow-cooling, volatile-rich magmatic events that allow unusually large crystals to develop. Those coarse crystals of feldspar, quartz and mica can be separated and sorted into clean, consistent mineral fractions. In Limpopo, these conditions produced pegmatite deposits that have been commercially mined and processed for industrial use for more than half a century.
The minerals that flow through this geological heritage — and through Elixir Minerals' supply chain — are Microbrite® potash feldspar, Microsil® high-purity silica and Mica. All three originate from these Limpopo pegmatite deposits. Their consistent chemistry, predictable particle characteristics and mineral purity are properties inherited from the geological environment that created them, refined and verified by decades of operational know-how.
The origin of our feldspar, silica and mica products is Limpopo Province in South Africa's far north — a geological region characterised by large, mineralogically consistent pegmatite bodies that have been commercially mined for industrial mineral production for over half a century. Ore is extracted, sorted, crushed and processed on-site to primary industrial grades before being transferred to final processing and classification.
The operational heritage of this source — the mine infrastructure, geological understanding, processing know-how and quality systems — is the foundation of the consistency that Elixir Minerals' customers rely on. This is not a new or untested source; it is an established industrial mineral operation with a demonstrable track record.
Elixir Minerals supplies products from a single, integrated manufacturing partner. Micronized's Limpopo operations mine and process feldspar, silica and mica directly from their own pegmatite deposits. Talc and barytes are sourced from long-standing supply partners and processed at Micronized's dedicated Benrose, Johannesburg facility — the same tightly controlled milling, classification and quality control operation that handles the full product range. This consistent manufacturing base, combined with established raw material partnerships built over decades, underpins the batch-to-batch consistency we aim for across every product we supply.
Direct access to integrated production at Limpopo Province and Benrose, Johannesburg. Containerised export. Full traceability at every stage. (Feldspar, silica and mica begin at ore extraction; talc and barytes enter the process at grade sorting, sourced from long-standing supply partners.)
Responsible sourcing is central to how we operate. Our supply partner, Micronized, maintains documented origin and traceability at every stage of production — from raw material intake through milling, classification and packaging to export. We are committed to transparency across our supply chain and are able to provide origin documentation on request.
Containerised export from South Africa to UK ports, with qualifying South African origin documented at every stage. Certificate of Analysis documentation accompanies each shipment. Full technical documentation (TDS, SDS, CoA) is available upon request for every order.
South Africa's position as a producer of industrial minerals is underpinned by geological conditions that are globally distinctive. The country's ancient Precambrian geology — including the pegmatite deposits of Limpopo Province — hosts raw material deposits valued for their chemical consistency and mineralogical stability.
These geological characteristics translate directly into commercially valuable product attributes. Pegmatite-derived feldspar from Limpopo Province delivers the alkali (K₂O + Na₂O) content and low Fe₂O₃ levels valued by ceramic and coatings manufacturers. Quartz veins in the same pegmatite ore bodies — crystallised late, from the silica-rich residual melt, as coarse crystals that separate cleanly from feldspar and mica — are processed into Microsil® at 98.5% SiO₂.
The quality of a mineral product is shaped equally by the processing capability that transforms raw ore into a specified industrial grade. At the Limpopo Province operations, processing capability encompasses ore sorting, crushing, primary milling, classification and precision particle sizing — with particle size distributions verified by wet sieve analysis.
The Johannesburg facility adds dedicated milling, classification, micronising, quality control and packaging capability. Critically, this is the Johannesburg arm of the same production partner — same organisation, same quality culture, same documentation standards. The 50+ year operational heritage applies to the full range.
Established mine infrastructure, developed processing capability and South Africa's operational cost base enable competitive pricing without compromising specification or documentation quality.
South Africa's industrial minerals sector continues to invest in downstream processing capability — producing specification-grade products that meet the requirements of international manufacturing sectors.
Documented South African origin and full traceability from source to UK delivery — built into every Elixir Minerals order, not a marginal or speculative benefit.
