Mining-critical chemical supply, sourcing and custom manufacturing.
O&I supplies and sources high-usage mining and process chemicals, laboratory consumables and sample preparation equipment with a focus on reliability, cost efficiency and quality.
Outsourced manufacturing and sourcing you can trust.
O&I manages and executes custom manufacturing projects and collaborates with partners nationwide to source specialised chemicals, and deliver valuable, scarce consumables and chemicals within agreed timeframes.
Our mission
As a preferred outsourcing partner to mining operations and laboratories, we provide product sourcing and manufacturing that is cost-effective, on time and of exceptional quality.
We manage sourcing end-to-end — from specification and supplier selection to logistics coordination — to reduce downtime risk and total landed cost.
Industries we support
Our team understands how critical reliable supply is for operations.
- Mining and mineral processing
- Water and wastewater treatment
- Analytical laboratories & sample prep facilities
- Industrial and manufacturing sites requiring niche chemicals
- Research and commercial analysis
High-usage mining and process chemicals (illustrative list).
We support mining operations (including mineral processing and water circuits) with chemical supply, sourcing and custom manufacturing. The categories below align to high-probability, near-term opportunities typically used at mines and process plants.
Water treatment chemicals
Typical products used across mine water, process water and effluent circuits.
- Polyacrylamide (PAM) flocculants — anionic / non-ionic / cationic (incl. thickener flocculants)
- Ferric chloride (coagulant)
- Aluminium sulphate (alum) (coagulant)
pH control chemicals
Core reagents for neutralisation, leaching support, and water circuit control.
- Caustic soda (sodium hydroxide)
- Hydrochloric acid (HCl)
- Sulphuric acid (H2SO4)
- Lime (CaO / Ca(OH)2) — quicklime, hydrated lime, lime slurry (where applicable)
Dust suppression chemicals
Transport-heavy, high-usage products where local supply can be advantageous.
- Calcium chloride (CaCl2) — dust suppression / hygroscopic salt
- Magnesium chloride (MgCl2) — dust suppression / hygroscopic salt
Cleaning & maintenance chemicals
Commonly used across workshops, plants, laboratories and utilities.
- Descalers (scale removal / acid cleaning)
- Degreasers (industrial cleaning)
- CIP chemicals (clean-in-place) — where applicable
Utility chemicals
Ongoing consumption items that support stable plant operations.
- Antiscalants (scale inhibition)
- Corrosion inhibitors (asset protection)
Mineral processing applications supported
Common “use-cases” we support in mining plants (industry-standard terminology).
- Flotation reagents & aids (collectors / frothers / modifiers, where applicable)
- Grinding aids & dispersants e.g., propylene glycol (milling performance & slurry rheology control)
- Coating / anti-agglomeration additives (material handling & process stability)
- Wastewater / effluent treatment reagents (coagulation / flocculation support)
- Flotation thickener / tailings thickener flocculants (clarification & thickening performance)
