The Optima Process

A water-only process for high quality coal fines production.

Optima Process for Coal

The Optima process was developed with the purpose of maximising yield to coking and metallurgical coal from coal fines. The system also produces a secondary thermal coal product.

The process is designed for low footprint, minimal water consumption and high feed throughputs.

Coal

The Optima process uses low density cut points to produce high quality, dewatered coal fines product. The process encompasses three key processes – feed preparation, low cut density separation, dewatering. Product moistures of 20-25% are achievable.

The separation envelope is -5+0.075mm. The system is used to recover coal from material such as filter cake, thickener underflows, slimes dams and run of mine coal fines.

An agglomeration process and economic evaluation option can be investigated for the production of a high quality ‘peas’ product.

Look at it differently

The export market offer higher prices for the coal industry. Producing a high-quality product for blending purposes improves the overall export product yield and revenues.

Using the Optima process improves process plant economics reduced environmental liability due to reduced discard quantity. The reduced discard quantity also reduces operating costs such as tailings deposition, transportation, diesel etc.

The low plant footprint means reduced capital outlay.

Our team of engineers offer a free process evaluation. During this process we will look at things differently and find opportunities to:

  • Increase production
  • Reduce electricity and water consumption
  • Improve product quality
  • Reduce your environmental liability

 

Green Technology

Our green technology offers low process water and energy consumption, reducing your eco footprint while boosting revenue.

Maximised Yield

The Optima process was developed with the purpose of maximising yield to coking and metallurgical coal from coal fines.

Max Recovery

The system is used to recover coal from material such as filter cake, thickener underflows, slimes dams and run of mine coal fines.

Increased Revenue

By offering higher throughput at a lower installation cost and footprint, you save money in the short and long term.
