OUR MINERALS

Cobalt

An important industrial mineral supporting advanced materials, energy technologies and modern manufacturing.
COBALT OVERVIEW

What Is Cobalt?

Cobalt is a metallic element valued for its role in rechargeable batteries, high-performance alloys, catalysts and specialised industrial materials. It is commonly recovered as a by-product of copper and nickel mining.

Its commercial importance depends on ore characteristics, mineral associations, processing requirements and the quality specifications of the intended market.

APPLICATIONS AND USES

Where Cobalt Creates Value

Cobalt’s chemical and physical properties make it useful across several industrial sectors, with applications varying according to product grade and material specifications.

GEOLOGY AND MINERAL OCCURRENCE

Understanding Cobalt-Bearing Ores

Cobalt occurs in several geological settings, frequently alongside copper or nickel minerals. The composition and distribution of these minerals influence exploration methods, extraction techniques and processing routes.

EXTRACTION AND PROCESSING

From Mineral Discovery to Market-Ready Materials

01. Exploration

Geological mapping, sampling, drilling where appropriate, and laboratory testing.

02. Extraction

Mining methods selected according to deposit geometry, depth and site conditions.

03. Processing

Crushing, separation and concentration, depending on the ore and processing route.

04. Refining and quality control

Further treatment and testing where required to meet applicable product specifications.

05. Commercial delivery

Product verification, documentation, logistics and delivery according to agreed terms.

RESPONSIBLE SOURCING AND SUSTAINABILITY

Responsible Mineral Development

Health & safety

Prioritise safe working practices and appropriate operational controls.

Environmental stewardship

Address water use, waste, emissions and rehabilitation according to site requirements.

Traceability & sourcing

Promote appropriate documentation, supply-chain transparency and due diligence.

ASTRA'S APPROACH
