feb 02, 2018 self-driving ore carriers using the same type of automation technology as seen in other self-driving vehicles, ore-carrying vehicles such as above ground earth movers and underground ore carriers are able to work hours a day, while removing people from the dangers inherent in their work areas. some of these above ground ore carriers are minerals review sensor-based ore sorting technology in miningpast, present and future christopher robben and hermann wotruba tomra sorting solutions mining, feldstrasse 128, 22880 wedel, germany amr unit of mineral processing, rwth aachen university, lochnerstrasse 420, 52064 aachen, germany correspondence: tel.: 103 the lkab iron ore mine in kiruna is a computer automated, highly specialized world-class mine facility. technology aims to increase efficiency while limiting environmental damage and contamination. unfortunately, the mining process is inherently a devastating process to the local natural environmentthe barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.refinements in this technology could lead to defining liberation in an ore, thus eliminating overgrinding and reducing both energy usage and excessive loss of fine-grained particles. the mineral industry needs innovations in instrumentation for size measurements, chemical analysis, and physical characterizations.
