"Nice pic in front of our Tomra XRT set up at Mighty Mt Carbine #Tungsten. This is one of a pair of Tomras that has been treating our low-grade stockpile commissioning ore for the EQR JV with CRONIMET. We are counting down the days until we access primary ore from the Andy White openpit and run that through our crushing, screening, sorting and gravity circuits that have been upgraded over the past two years. We look forward to reporting on how the high-tech sorters deal with higher-grade primary ore. Stay tuned."

For any new users I suggest reading the article. Snippet below.
"High recovery rates with considerable savings with TOMRA’s XRT sorting technology Mt Carbine is currently mining the 12 million tons of low-grade historical stockpiles. The ore is crushed and screened at 6 and 40mm. Two TOMRA XRT sorters are used to pre-concentrate the feed in the 6-40mm size range before processing in the wet plant.
Approximately 10 per cent of the sorters’ feed mass is ejected as product with a high recovery of Tungsten well over 90 per cent. This means that only 10 per cent of the mass is processed in the wet plant, dramatically cutting running costs, reducing the required size of the wet plant, as well as saving water and energy.
“We let the technology do the work for us and take out all the rubbish and we’re left with just the pure Tungsten to send to the processing plant – and we do that very cheaply using the sorters,” MacNeill explained.
“One of the best things about the TOMRA XRT is the cost savings to the operation. It costs approximately $1.5 Australian dollars/ton to sort and then it costs 14 Australian dollars/ton for wet processing: as we take out 90 per cent of the sortable fraction mass, we only have to process 10 per cent of the higher grade concentrate and natural -6mm material while maintaining recovery, so our cost benefit is obvious. We couldn’t afford to run this waste dump if we had to crush everything to 6mm and process it through the wet plant, it would be too low grade and costly.”
