Westfarmers - Curragh Mine
- Owner: Westfarmers
- Project: Coal Handling Systems
- Location: Curragh Mine, Bowen Basin, Australia
- Scope: Engineering
Project Background
Roberts & Schaefer undertook a series of benchmarking, peer review and feasibility studies to identify the optimal method of increasing the capacity of the existing mine operation at Curragh.
The studies initially considered a brown field expansion of the existing facility before settling on the installation of a new 1200 TPH stand alone coal preparation plant. The plant is to be sited adjacent to the existing facility allowing it to utilize infrastructure and coal storage facilities already in place.
The study investigated the tie in of the new plant to existing raw coal and product handling facilities. Detailed technical design, costing and scheduling was completed in developing the feasibility study.
The study included a:
- 1200 TPH coal preparation plant, two stage to produce both coking and thermal coal products
- Primary and secondary heavy media cyclones (50mm x0.5mm)
- Column flotation circuit (0.5 mm x 0mm)
- Spiral circuit - retreat for flotation tails
- Belt filter dewatering
- Coking and thermal products
