About Elixir Minerals

Production-Backed Supply from Source to UK

Elixir Minerals is the UK representative for premium industrial minerals produced by a single, integrated South African manufacturing partner. We supply functional mineral fillers and aggregates to UK and European manufacturers.

Our supply chain spans two operational hubs: pegmatite mining, milling and on-site processing in Limpopo Province, and a dedicated milling, classification, packaging and quality control facility at our Benrose, Johannesburg factory.

This direct access to integrated production gives our customers production-backed supply continuity, controlled chemistry, and technical documentation sourced from the operation itself.

Why Choose Elixir Minerals

Six Reasons to Switch

What sets Elixir apart from generic mineral traders and distributors.

01
Production-Backed Supply — Direct from Source to UK

Unlike traders who simply buy and resell, Elixir Minerals has direct access to integrated mining and processing operations in South Africa. Your supply is secured from the source — not dependent on third-party intermediaries.

02
Consistent Chemistry, Every Batch

Our feldspar, silica and mica originate from the same Limpopo Province pegmatite deposit, mined by a production partner with over 50 years of operational heritage; talc and barytes are processed under the same quality system at our Benrose, Johannesburg facility. Published chemistry ranges and batch QC support consistent formulation performance.

03
Tightly Controlled Particle Size Distribution

Grade selection from d50 6.8μm through to coarse screened grades. Milled and classified, with particle size quality-controlled by wet sieve analysis and laser-diffraction PSD data available for our micronised feldspar and silica grades.

04
Full Technical Documentation Pack

Technical Data Sheets, Safety Data Sheets and Certificates of Analysis are available for every product on request. The talc raw material for MicroTalc® and Pharmatalc® is tested quarterly by an independent laboratory for asbestos (NIL detected) and heavy metals.

05
Responsible Mineral Supply

Sourced from integrated, production-backed operations in South Africa with documented origin and traceability at every stage — a supply chain built on accountability, not just proximity.

06
UK Technical Support & Fast Response

Our UK-based team is available for grade selection, substitution trial support, specification queries and supply planning. We aim to respond to all enquiries within one business day.
