TUNRA Clean Coal has developed a revolutionary Slurry Ash Monitor (SAM) that allows you to constantly and accurately monitor a tailings stream to help maximise the rate of coal (or other mineral) recovery during processing.
The Slurry Ash Monitor has been developed and successfully trialled in the coalfields of the Hunter Valley in Australia with outstanding results.
Case studies have yielded dramatic increases in coal recovery for both low and medium grade thermal coals that are projected to provide enormous returns for a low initial investment.
For a modest initial outlay, the SAM finally delivers a reliable and easy to use monitor that reveals exactly how much valuable mineral is being lost through your tailings stream.
Based on an innovative formula, the SAM is:
- Flexible and can be installed on any type of slurry feed
- Compact and easily installed
- Adaptable to existing plants’ communications network
- Easy to read and understand
- Safe, with no dangerous voltages used
- Low-maintenance
- Fully supported and backed up by experts.
Filling a much-needed gap in the processing market, the SAM is incredibly accurate in monitoring the ash value of a tailings stream, correlating closely with actual laboratory results.
In response to continuous and real-time SAM data, the operators were able to optimise the flotation process to provide a huge increase in the yield of coal recovered. The financial benefits from two case studies are summarised below:
After fitting the SAM to a coal preparation plant operating 6,000 hours per year, with a feed of 1,000 tonnes per hour and a fines feed of 200 tonnes per hour, the average tails ash was increased by 20 percentage points, increasing the coal yield by an amazing 51 tonnes per hour.
Based on a coal price of $AUS 100 per tonne, the value of the coal recovered after SAM installation is worth $AUS 5,100 per hour or $AUS 30million in just one year.
The results were even more dramatic for a plant with the same flow rates as the first Trial, with the average tails ash increased by more than 50 percentage points, increasing the coal yield by 140 tonnes per hour.
Based on a coal price of $AUS 100 per tonne, the value of the coal recovered in this case is worth $AUS 14,000 per hour or $AUS 84million over a year. In most cases the value of the product coal will be greater than $AUS 100 per tonne.
