This is the 11th and last article in our case study series on auditing with process mining. The series is written by Jasmine Handler and Andreas Preslmayr from the City of Vienna. You can find an overview of all the articles in the series here. Within this case study, we followed the 9-step model from Figure 3 to apply process mining in our audit.

The process of finding a concentration of minerals is called mineral exploration. Mineral exploration can be complex and has numerous stages; it is often easier to think of it as a cycle. Just as treasure seekers …
mineral, naturally occurring homogeneous solid with a definite chemical composition and a highly ordered atomic arrangement; it is usually formed by inorganic processes. There are several thousand known mineral …
Mineral and coal processing encompasses unit processes required to size, separate, and process minerals for eventual use. Unit processes include comminution (crushing and grinding), sizing (screening or classifying), separation (physical or chemical), dewatering (thickening, filtration, or drying), and hydrometallurgical or chemical processing.
Mineral extraction sites, which include strip mines, quarries, and underground mines, contribute to surface water and groundwater pollution, erosion, and sedimentation (see Chapter 14). The mining process involves the excavation of large amounts of waste rock in order to remove the desired mineral ore (Fig. 12.6). The ore is then crushed into ...
Lithium Mining Process Lithium is historically known to be produced from two sources: brines and hard rock mining. Lithium produced from brines is a cost-efficient process. Also, Lithium is processed from brine, …
The minerals on Federal lands are divided into three categories, each subject to different laws and regulations. Locatable, which are subject to the Mining Law of 1872, as amended, include gold, silver, copper and other …
The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and …
Mineral processing methods Mineral processing techniques have been suggested for the recovery of nickel-based alloys from spent batteries. The process involved hammer milling, magnetic separation, knife milling, a second and a …
The Mining Process Finding new mineral reserves is critical to the success of our company. Locating, extracting and processing these natural resources is a multi-year process that involves complex scientific, …
Our solutions can be employed for continuous, non-contact monitoring of elemental and mineralogical composition as well as the prediction of process relevant parameters in a large range of mining applications such as iron, bauxite, copper, nickel or coal. On-line Analysis - A rapid payback for mineral processing efficiency Watch now
While producing 66,000 tons a year of battery-grade lithium carbonate, the mine may cause groundwater contamination with metals including antimony and arsenic, according to federal documents. The...
Below is a list of equipment used at each stage of mineral processing: Crushing and grinding equipment Cone crushers Gyratory crushers Jaw crushers SAG mill grinders Rod mill …
About 10,000–1000,000 Gt of total carbon can be stored in naturally occurring mineral deposits 2. Mine tailings resulting from nickel extraction 3 and diamond production 4 and chrysotiles...
A mining geologist is responsible for mapping out the locations of valuable minerals and will use aerial photographs, field maps, and geophysical surveys, to determine where valuable materials are and estimate how much of those materials are in that location.
The first process that most of the ores or minerals undergo after they leave any mine, is mineral processing or mineral/ ore …
The primary methods used to extract minerals from the ground are: Underground mining Surface (open pit) mining Placer mining
Mineral extraction sites, which include strip mines, quarries, and underground mines, contribute to surface and groundwater pollution, erosion, and sedimentation. The mining process involves the excavation of large amounts …
1. Locate Potential Deposits One of the first steps of mineral exploration is to locate areas that are likely to yield mineral deposits. Since mineral deposits tend to form in clusters, prospective areas may be near other areas of known mineralization or …
It has been estimated that more than two-thirds of the world's yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.
The utilization of multiple minerals is more effective in characterizing the comprehensive magmatic process, as different minerals undergo crystallization at different stages. Moreover, the implementation of mineral thermobarometers can delineate the alteration of ƒO 2 and volatile components during the magmatic evolution and magmatic ...
About 10,000–1000,000 Gt of total carbon can be stored in naturally occurring mineral deposits 2. Mine tailings resulting from nickel extraction 3 and diamond production 4 and chrysotiles ...
The four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw …

What is process mining? Process mining applies data science to discover, validate and improve workflows. By combining data mining and process analytics, organizations can mine log data from their information systems to understand the performance of their processes, revealing bottlenecks and other areas of improvement.
Plans are assessed regarding the: 1) the mining process/technology that will be used, 2) building of access roads for transportation, 3) identification of resources such as power and water sources, and 4) construction of …

Mines can be repurposed for other uses such as for agriculture, solar panel farms, biofuel production or even recreational and tourist use. Mine closure process: 1. Shut-down: Production stops and workers are reduced. Some skilled workers are retained to permanently shut down the mine. Re-training or early retirement options are sometimes ...
The four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which new minerals form at the …
