About O&I Chemicals

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
Products & Services

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.

Important: The products and categories below are illustrative, not exhaustive. We can source or manufacture additional items based on your specification, grade and required volumes.

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)

Representative product categories (illustrative, not exhaustive)

Below is an illustrative snapshot of common high-usage products in mining operations and process plants (e.g., mineral processing, water circuits, maintenance and utilities). We can supply additional products, grades and packaging configurations on request.

  • Lime (quicklime / hydrated lime / lime slurry)
Supports: pH control, neutralisation, process control.

Dust suppression

  • Calcium chloride (CaCl2)
  • Magnesium chloride (MgCl2)
Supports: dust suppression on haul roads, stockpiles and materials handling areas.

Plant cleaning & maintenance
