Mining of association rules is one of the most adopted techniques for data mining in the most widespread application domains. A great deal of work has been carried out in the last years on the development of efficient algorithms for association rules extraction. Indeed, this problem is a computationally difficult task, known as NP-hard (Calders, 2004),

A review of the implications and challenges of manganese removal from mine drainage.
Chemosphere, 2019Manganese (Mn) is the third most abundant transition metal in the Earth's crust. Decades of increasing worldwide mining activities have inevitably led to the release of large amounts of this metal into the environment.

Group 14 used data-mining strategies to evaluate a number of issues, including appropriate diagnosis, haplotype estimation, genetic linkage and association studies, and type I error. Methods ranged from exploratory analyses, to machine learning strategies (neural networks, supervised learning, and tree-based methods), to false discovery rate control of

The Samarco mine tailing disaster: A possible time-bomb for heavy metals contamination?
Science of the Total Environment, 2018In November 2015, the largest socio-environmental disaster in the history of Brazil occurred when approximately 50 million m3 of mine tailings were released into the Doce River (SE Brazil), during the greatest failure of a tailings dam worldwide.

Seafloor morphology plays a key role in submarine mineral exploration as precious minerals are associated with specific geomorphological settings. Mn-nodules occur in abyssal plains, seafloor massive sulphides are strongly connected to volcanic areas and sand, gravel and other marine minable aggregates are deposited in coastal environments.

Rome came into possession of a wide variety of mineral resources as a result of imperial expansion. Large mines were opened up in many provinces, especially in the Iberian Peninsula, Gaul, Britain, the Danubian provinces, and Asia Minor. Pollution records show that the scale of mining in antiquity peaked during the Roman period and
