Beneficiation

Our services include mineral processing and coal upgrading.

Mineral Processing

Processing Sampling
Extraction of a processing sample

We support all aspects of mineral processing, from initial sampling and pilot-scale testing through to front end engineering and design of processing system for crushing, grading, cleaning, separation, agglomeration and the separation of solids from liquids. Clients know that they can rely on our extensive experience throughout the world to deliver cost-effective and environmentally sustainable minerals processing consulting across the full range of minerals, metals and energy sector deposits.

Specifically, we provide expertise, advice, studies and assessment covering the following:

  • Planning and supervision of sampling
  • Laboratory and pilot-scale testing
  • Process block and flow diagram development
  • Water block and flow diagram development
  • Mass/water and metal balance development
  • Dimensioning and specifications of equipment
  • Automation and process control
  • Water management
  • Basic and detailed engineering (Front End Engineering and Design (FEED) studies)

Ahead of full-scale mining development, our planning and supervision of sampling services help guide crucial investment decisions by analysing a small, representative portion of the bigger mass to provide an unbiased assessment of the grade, content and potential economic value of the resource for processing purposes.

Coal Upgrading – Coking Technology

Upgrading of run-of-mine (ROM) to remove impurities, add value, meet client quality specifications and reduce shipment costs is becoming increasingly important as the volume of globally traded coal continues to increase. DMT can offer a wide range of technical expertise in most coal upgrading processes, including coal washing, coal briquetting and coal pyrolysis. Our experience in coke-making is exceptional and we provide a comprehensive range of services from consulting, testing and assessment to planning and constructing coke plant equipment.

We invest significantly in research and development to optimise the performance of coking plants, techniques and instrumentation for emission reduction and improving coal blends and coke quality. Please also visit our Engineering section.
