High quality mineral products and services supporting the oil, gas and mining sectors.

What We Do

Manufacture & Supply

Micronised Minerals provides a complete service vertically integrated to meet our client requirements.

Mining Sector

Micronised Minerals is the only major manufacturer of specialty reagent products in Northern Australia and supplier of Chememan Quicklime and Hydrated lime to numerous projects within Northern Australia.

Oil and Gas

Micronised Minerals mines and manufactures Barite, a high purity Barium Sulphate (BaSO4) sourced from mineral leases south of Darwin.

Civil & Infrastructure Sector

Micronised Minerals specialise in the fine grinding and blending of synthesised lime reagents for treatment of acidic soils and substrate stabilisation.

Agriculture Sector

Micronised Minerals Agriculture minerals are specially processed and formulated to maximise the Effective Neutralisation Value (ENV) creating a balancing agent for low pH soils.

Materials Handling, Storage & Delivery

Micronised Minerals purpose-built facility is strategically located close to the Darwin Port and Rail terminals and has the capability to provide a complete service.

Whole of Service with Innovative Design

MMA has the ability to integrate skills and technologies to design equipment and manufacture the best products and implement economic environmental solutions.

We have developed a specialised capability in the application of calcium carbonate and its derivatives to decontaminate acid water produced on mines sites, restore pH balance to soils and treatment of acid sulphate soils in the agricultural and civil/industrial sectors.

Provision of engineering and chemical design – including product development, in-house and third party laboratory testing, engineering and construction of large scale water treatment systems.

pH Management & Control – An Informed Economic Innovation

 

Micronised Minerals was awarded Australian Patent 2013209309 for “Method and Apparatus for Acidic Surface Water Treatment” (Micro Reactor Technology) in 2018 and is continuing the patent development of its locally developed reagent “Enviro Catalyst”. The innovative in-situ acid mine water treatment process is an informed economic innovation for decontamination of acid mine water containing high levels of dissolved metals stored on active and legacy mine sites. When compared to the common treatment options used on mine sites, the improvement in water quality and subsequent reduction in toxicity after using the Micronised Minerals Reagent has proven favourably in price and detoxification outcomes.

Using our patent technology and locally developed reagent, Micronised Minerals successfully completed decontamination at Vista Gold Australia’s Mt Todd mine water pit of 10.3 billion litres of acidic water. The body of water has transformed from a level of high toxicity to aquatic life to one where 99.8% of metals have been removed. The local flora and fauna recovery including the native frog population were evident post treatment.
