Mandala Metals is an advanced metallurgical refinery and technology company, processing copper, titanium, PGMs, galena, antimony, precious metals, and rare earth elements — using co-developed, internationally patented electrolytic and hydrometallurgical technology built for the critical metals demands of the global clean energy transition.
Every metal we process is critical to the global energy transition — from the copper wiring inside every solar inverter, to the rare earths inside every EV motor magnet, to the antimony enabling next-generation solid-state batteries.
Mandala Metals co-develops its own machinery and processing equipment with local Indonesian metallurgical engineering experts — integrating internationally patented technology into our production lines. This creates a defensible cost and performance advantage no foreign competitor can replicate.
Core electrolytic refining cells operate at significantly lower temperatures than conventional smelting, licensed from internationally patented technology. Achieves 99.99% purity while consuming 40% less energy and eliminating SO₂ emissions entirely.
Mandala co-designs and builds refining cells, hydrometallurgical reactors, and recovery systems with Indonesian metallurgical engineering firms — purpose-built for our feedstock chemistry. Lower capex, faster maintenance, full IP control.
Patented solvent extraction and electrowinning process for copper and cobalt separation from complex polymetallic ore — enabling processing of mixed feedstocks that conventional refiners cannot economically treat.
Multi-stage solvent extraction circuit for rare earth element separation, delivering individual REE oxides at >99% purity — built on patented leaching chemistry adapted to Southeast Asian ore profiles.
Custom-engineered anode slime processing units, electrolyte regeneration reactors, and slag valorization equipment — turning every waste stream into a recoverable product with zero hazardous discharge.
The Mandala Circuit is our branded closed-loop refining architecture — a six-stage process where every output, byproduct, and waste stream is captured, re-valued, or recirculated. It is the operational embodiment of our name: a complete, self-reinforcing cycle.
Anode slimes from copper and nickel electrolysis are processed in-house to recover platinum, palladium, gold, and silver — transforming what other refiners discard as waste into a high-value secondary revenue stream.
Spent electrolyte (CuSO₄, H₂SO₄, REE leachate) is chemically regenerated and fully recirculated. Zero liquid waste discharged. Water recovery >90%.
Process slag is converted to construction aggregate or slag wool insulation. Residual metals are re-introduced as secondary feedstock in the next processing cycle.
Electronic scrap, industrial offcuts, end-of-life autocatalysts, and spent galena ore are accepted as supplementary feedstock — enabling urban mining alongside primary ore processing.
Our electrolytic and hydrometallurgical processes are inherently lower-energy than pyrometallurgical smelting. Combined with co-developed equipment optimized for our feedstock, we achieve efficiency metrics benchmarked against best-in-class global refiners.
vs. conventional pyrometallurgical smelting. Electrometallurgy operates at a fraction of the thermal energy required by smelters.
Single facility handles Cu, Ti, PGM, Galena, Sb, precious metals, and REE concurrently — unlike single-metal refiners.
Every waste stream — liquid, solid, and gaseous — is captured, treated, recovered, or recirculated through the Mandala Circuit.
Consistent purity across all metal streams — matching or exceeding LME and LBMA delivery standards.
Co-developed with Indonesian metallurgical engineers — dramatically lower capex vs. imported European or Japanese refining equipment.
Core electrolytic and REE separation processes protected by internationally granted patents — a defensible technology moat.
Institutional investors increasingly require demonstrable ESG credentials. Mandala Metals is designed from the ground up with environmental, social, and governance standards as operational requirements — not afterthoughts.
Electrolytic process eliminates pyrometallurgical SO₂ emissions. Closed-loop water system. Renewable-sourced electricity target by 2026. Zero hazardous discharge from any process stream.
Local workforce development, fair-wage employment in the metals sector, and community engagement programs in sourcing regions across Indonesia and Southeast Asia.
Independent board oversight, transparent assay and pricing practices benchmarked to LBMA and LME. Full chain-of-custody documentation for every batch processed.
Our portfolio is deliberately constructed around the critical metals that renewable energy, electrified transport, and energy storage require — and which face the most acute supply deficits globally over the coming decades.
Every solar panel, wind turbine, EV charger, and grid upgrade requires enormous quantities of copper and silver. Demand for copper alone is projected to triple by 2050. We supply high-purity cathode copper and refined silver from both primary ore and galena co-processing.
Nd-Fe-B permanent magnets (requiring our REE) power every EV motor and wind turbine generator. Antimony trioxide from our stibnite processing enables next-generation solid-state batteries and EV pack fire suppression. Both face severe supply concentration risks.
Platinum is the critical catalyst in PEM electrolyzers that produce green hydrogen. Iridium — the anode catalyst — sees barely 7 tonnes produced globally per year. Titanium provides corrosion-resistant structural metal for hydrogen infrastructure. Our PGM recovery and titanium processing positions us squarely in the emerging hydrogen value chain.
We are actively building strategic relationships across capital, technology, and offtake. Each partnership tier is structured for long-term value creation — not transactional commodity supply.
Direct equity participation in Southeast Asia's most technically advanced critical metals refinery — at the intersection of supply scarcity, energy transition demand, and proprietary process technology.
Co-develop next-generation processing technology, integrate as a certified refining partner in your supply chain, or leverage our Southeast Asian feedstock network. We seek partners who bring complementary IP, market access, or metallurgical expertise.
Secure long-term, certified supply of copper cathode, titanium sponge, PGMs, REE oxides, antimony metal, and precious metal bullion — with transparent LME/LBMA-benchmarked pricing and full chain-of-custody documentation.
Whether you're an investor, a technology collaborator, a mining company seeking downstream refining, or an industrial buyer requiring certified critical metals — we want to hear from you.
