Ore Sorting Tests Point to Process Efficiency
Dalradian Resources, a Canadian junior exploration and development company, announced positive ore sorting test results based on a bulk sample of mineralized development material from several of the veins at its Curraghinalt gold project in Northern Ireland. Testing was carried out by Outotec at their TOMRA sorting test facility in Wedel, Germany, on approximately 5 metric tons (mt) of material grading 9.52 grams/mt of gold. Using X-ray and laser technology, plus additional screening prior to processing, the amount of non-mineralized material that would be sent to the mill in an operating mine was reduced by 35.8% and the grade increased by 54.6% to 14.72 g/mt of gold with a gold recovery of 99.3%.
