Variability in hardness and mineralogy of run-of-mine ore is a serious problem that reduces throughput and causes recovery issues downstream. NTWIST addresses this issue by offering a solution that identifies feed origin and provides grade and lithology tracking throughout feed stockpiles. With the help of our mill feed identification and tracking solutions, a gold operation processing 2 mil tons of ore from multiple sources can increase throughput and improve recovery to generate additional US $3 mil/year
