Preventing haul truck-related fatalities in open pit mining using gamified training simulation

Haul truck driving remains to be the most dangerous occupation in the mining industry (Kecojevic et al., 2007), leading in fatalities over other occupations in the mining industry. As the transition to autonomous haul trucks over the coming decades will not address thisproblem today, an immediate solution is needed that can be adopted at short...

Investigation of decarbonization options for load and haul equipment in quarry mining with case study Ipoh quarry, Malaysia

The importance of decarbonization in various industries is growing significantly, especially when it comes to LHD equipment in the minerals and metals industry. Conventional diesel load and haul (LHD) equipment used in quarrying and mining operations have drawbacks that result in the emissions of hydrocarbon and greenhouse gases that need to be...

Optimised fuel consumption of hauling mobile equipment achieved from speed optimisation using Simulated Annealing

The mining industry is a significant contributor to greenhouse gas emissions and operational costs. The transportation of materials within mining operations, especially using diesel-powered trucks, accounts for a substantial portion of both emissions and costs. Optimizing fuel consumption in this context is crucial for environmental...

Integrated Mapping of Rare Earth Element Mineralization Using Hyperspectral Imaging and Laser Induced Fluorescence Spectroscopy in Drill Cores from the Storkwitz Carbonatite, Germany

The growing importance of rare earth elements (REEs) in sustainable technologies necessitates anefficient assessment of potential resource targets within the European Union. Traditional analyticaltechniques for REE determination have drawbacks like destructive and time-consuming samplepreparation, but hyperspectral imaging (HSI) and laser...

Mechanical separation and acid leaching: potential to decrease the environmental impact of the graphite tailings by recovering sulfide sulfur and heavy metals

The electrification of the world and the green transition are expected to increase the demand for energy storage technologies such as lithium-ion batteries. This will increase the demand for raw materials used in batteries, such as graphite. Further, due to geopolitical risk and the need for sustainable sources, graphite mining is also of...

Applications of geophysical measuring methods for the exploration and securing of old mine workings near the surface using the example of the former lignite mine “Robertshall”

In the former lignite mine "Robertshall" near Hamburg damage to the surface was caused by the collapse of underground cavities originating from old mine workings of a lignite mine which had been in operation between 1920 and 1922. During the investigation of the subsurface by drilling it was noticed that the existing mine plans are incomplete....

Sensor-Based Sorting of Post-Consumer Plastic Packaging: Analyzing False Calls of Near-Infrared Sensor Systems

Starting from the 1950s, plastic has found its way into many aspects of life; from packaging to transportation and construction. The annual global plastic production was estimated to be 330 million metric tons in 2017 and will be doubled within 20 years if the current growth rate persists. In Europe, packaging accounts for 40% of the annual...

Passive scrap singulation for demand-driven sorting

Aluminium is a vital component of the world's economy, thanks to its versatile applications. However, the environmental impacts of primary production result in a growing desire and societal pressure to develop more efficient recycling techniques. Secondary aluminium is produced at 5% of the energy consumption used to produce primary aluminium....

Ammonia recovery from calciner off-gas: The effect of reclaiming ammonia by direct injection into the plant system

Ammonia has been recognized as an effective leaching agent in hydro-metallurgical processes for the recovery of metals\cite{AmmLeach2013}. These processes result in ammonia-metal crystals, whereby in the last step, water and ammonia are removed from the crystals by a calcination process. In the past, the vaporized ammonia is considered a waste...

Site specific calibration of laser induced breakdown spectroscopy for rapid elemental analysis of gold ore drill core samples

Site-specific calibration of laser induced breakdown spectroscopy (LIBS) analysis can be achieved by presenting known geological sample data to update algorithms, therefore improving analysis of unknown samples post-calibration. The goal of this project is to optimise drill core analysis by LIBS for samples from Kittilä gold mine. In total 227...

Cut-off Grade Based Stope Optimisation to Maximise Value at the Garpenberg Mine

This research was aimed at determining the influence parameters have on the cut-off grade of sublevel stopes in the Garpenberg underground mine, and combing these to maximise value at the mine. Garpenberg is a multi-deposit poly-metallic mine owned by Boliden AB. Cost calculations were performed on data from 2018 to derive costs for each deposit...
