Who We Are

A New Standard in
Global Mining

United Metals specialises in electrorefining, producing high-purity metals pivotal for technological innovation and sustainable development. Our state-of-the-art refineries, strategically located in the Democratic Republic of Congo, Zambia, and Zimbabwe, are designed to maximise efficiency and minimise environmental impact.

We predominantly process base metals such as copper, nickel, gold, tin, and antimony, adhering to the highest industry standards. By combining advanced electrochemical techniques with ethical practices, we ensure the delivery of premium products essential for various industries.

Operating across Zambia, Zimbabwe, Tanzania, the DRC, India, Peru, and Mexico, we specialise in transforming polymetallic ores into valuable base and noble metals using state-of-the-art beneficiation techniques.

From resource extraction to global markets — our integrated model ensures that every gram of metal we produce is traceable, sustainable, and engineered to exceed the standards of the world's most demanding industries.
United Metals — Company Mandate
Mineral Processing

Beneficiation
Capabilities

United Metals employs state-of-the-art mineral processing and beneficiation techniques to maximise the recovery and purity of valuable metals from complex polymetallic ores.

Gravity Concentration
High-efficiency gravity separation utilises density differentials to separate high-value minerals from gangue. Deployed for cassiterite, chromite, and gold-bearing ores across our African operations.
01
Froth Flotation
Advanced flotation circuits with precision reagent dosing separate hydrophobic minerals from gangue. Applied to copper sulfides, antimony stibnite, zinc sphalerite, and nickel pentlandite ores.
02
Magnetic Separation
High-intensity magnetic separators process iron-bearing minerals including magnetite, hematite, and ilmenite. WHIMS technology enables fine-particle separation from complex polymetallic ores.
03
Electric Beneficiation
High-voltage electrostatic separation exploits differences in electrical conductivity between minerals. Particularly effective for cassiterite, tantalite, and coltan concentration in dry processing circuits.
04
Chemical Separation
Hydrometallurgical leaching combined with solvent extraction and electrowinning (SX/EW) recovers copper, gold, and other metals from oxide ores and complex concentrates with high selectivity.
05
Dewatering
Thickening, filtration, and drying circuits remove water from processed concentrates to meet moisture specifications for export. Filter press and vacuum disc filtration achieve consistent ≤8% moisture.
06
