Abstract
The lithological composition of the copper ore delivered to the mills, when recognised in advance, is considered as the most important factor for the proper settings of grinding/milling equipment that can both decrease the specific energy consumption of ore processing and increase metal recovery. In order to address this problem, the idea of the use of sensors for in-situ sensing with respect to adaptation to harsh environment of copper ore conveying in the underground mines was investigated. The in-situ sensors information carrying pellets, are planned to be used for annotating the copper ore for the needs of ore processing plants control. The improved identification of the lithological composition of ore can be achieved by combination of annotating the stream of transported ore with pellets that keep the information on the original location of the ore (when they are dropped into the transported bulk material), the data of the in-situ lithology derived from the digital, orebody structural and quality block model and the simulation analysis of the transportation system. The idea is being developed within the DISIRE project – a part of the SPIRE initiative, acting under the “Horizon 2020” framework program.
