Marker trials have been an important tool in the quest to understand flow in mass mines. Before Smart Markers were available, such trials were performed using steel pipes with ID numbers welded onto them. The pipes were installed in the mine’s ore body, with their codes and installation locations recorded. During the extraction process, the “tramp magnets” near the crusher that are designed to remove pieces of waste steel from the ore also picked up the steel pipe markers. Conducting trials in this way was labour intensive because mine staff needed to manually recover the markers from the tramp bins. This technique also lacked data precision.
By automating Smart Marker detection and providing high resolution data that can be easily viewed and interpreted, the Smart Marker System makes it easy to monitor and assess flow in mass mines.
Here’s how the Smart Marker System works:
