In England some shallow mine shafts were exhausted as early as the 14th century, making it necessary to go deeper and expand mining at the shaft bottoms. These remained small operations a record of 1684 shows 70 mines near Bristol, employing 123 workers. Greater depth created many problems. First, water could no longer simply be drained away.
This saves mining operations multiple millions in USD every month since iron ore beneficiation increases significantly the costs per ton of ore. Control of the moisture content on the mining conveyor belt NIR together with accurate monitoring of the composition of iron ore before shipment guaranties constant ore quality to avoids penalties.
