Process mining research historically has focused primarily on process-data analysis techniques, often neglecting the issue of the quality of the input data. Process …

What Is Mineral Processsing in Mining? Mineral processing is a form of extractive metallurgy that separates valuable minerals from the ore into a concentrated, marketable product. Mineral processing is also known as mineral dressing. Mineral processing is conducted at the site of the mine and is a highly mechanical process, with oversight …

The gold mining process is complex and lengthy — Gold exploration companies perform numerous tests to identify the size and quality of the ore body and a plan on how to extract the ore as safely, sustainably, and economically as possible before they can start mining gold.

Summary. Enterprises using low-quality data for process mining results in erroneous analysis and jeopardizes the overall output. EA and technology innovation leaders must manage the data quality issues to ensure data output integrity and improve decision making for process improvement and automation efforts.

Uranium Mining Overview. (Updated August 2023) In the last 60 years uranium has become one of the world's most important energy minerals. It is mined and concentrated similarly to many other metals. While uranium is used almost entirely for making electricity, a small proportion is used for the important task of producing medical isotopes.

Relatively deep deposits, or those with elongated or irregular shapes are typically mined from underground with deep vertical shafts, declines (sloped tunnels) and levels (horizontal tunnels) (Figures 8.2.1 and 8.2.2). In this way it is possible to focus the mining on the orebody itself. In some cases, the near-surface part of an orebody is ...

The quality tasks considered are; product/process quality description, predicting quality, classification of quality, and parameter optimisation. The review provides a comprehensive analysis of the literature from various points of view: data handling practices, DM applications for each quality task and for each manufacturing …

Process intelligence grounds the AI's responses in the process context, is based on the latest information to ensure responses are accurate and current, and uses event log data rather than sensitive information such as customer data, which helps avoid privacy and security issues. Process intelligence allows AI to understand any business ...

Mining lithium from evaporating ponds is a unique method of lithium extraction. It involves pumping lithium-rich brine into large evaporation ponds and allowing the water to evaporate over time. The concentrated brine is then processed to extract lithium, similar to the process followed in brine extraction.

Mine drainage is metal-rich water formed from a chemical reaction between water and rocks containing sulfur-bearing minerals. The resulting chemicals in the water are sulfuric acid and dissolved iron. Some or all of this iron can come out as solids to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage.

IMARC Chief Operating Officer Anita Richards says with AI driven advancements in exploration, mining, processing, and supply chain management, IMARC is a unique opportunity to hear from miners, academia, METS and consultants on the latest applications and strategies that are helping drive productivity, safety, quality and …

This chapter presents a discussion of impacts of uranium mining and processing operations on air quality, soil, surface water and groundwater, and biota. Much is already known about the environmental impacts of mining, both on-site and off-site, and that body of information provides a basis for this chapter. However, the primary emphasis …

The Impact of Recycling on Process Water Quality in Mineral Processing. It is now common practice to use substantial amounts of recycled water in mineral processing plants to minimise both environmental discharge and withdrawal of fresh water from often limited water resources. Recycled water additions to process water are frequently …

Therefore, mining process water quality assessment is becoming critical. Nevertheless, very few studies have investigated the suitability of the current analysis methodology practiced in certified …

Step 4: Event log preparation. While steps 2 and 3 consider the raw data, this step requires that the raw data is transformed into an initial event log. This log can be used for pre-study process mining purposes (step 6). Step 5: Event quality. In this step, the data quality is checked at the level of events.

A long list of additional dimensions of data quality can be defined – some examples include appropriateness, credibility, conformity, currency, relevance, and usability [].2.2 Process Mining. With the recent developments of the Internet of Things (IoT) and cloud-based technologies, massive amounts of data are generated by heterogeneous …

Grade control is the classification of reserves into ore, low grade, waste material or metallurgical types. X-Ray Fluorescence (XRF) is the most accepted analytic technology for grade control in mineral production …

The iron ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. In the United States, predominant iron ore is taconite which is a hard, banded, low-grade ore. Ninety-nine percent of the crude iron ore produced in the United States is taconite.

Data mining helps banks work better with credit ratings and anti-fraud systems and analyze purchasing transactions, customer financial data, and card transactions. Data mining also helps banks better understand their customers' preferences and online habits, which helps the institution design new marketing campaigns.

1 Introduction. Process Mining is a specialised form of data-driven process analytics where data about process executions, collated from the different IT systems typically available in organisations, is analysed to uncover the real behaviour and performance of business operations [ 2 ]. Without question, the extent to which the …

A village was set up to support 15,000 miners working in the ruby mine near Ambatondrazaka, Madagascar. Photo: Pardieu et al. (2017).
