Mechanochemistry: the mechanical activation of covalent bonds.
TL;DR: A survey of the classical works in mechanochemistry is given and the key mechanochemical phenomena into perspective with recent results from atomic force microscopy and quantum molecular dynamics simulations are put into perspective.

Mineral-Induced Formation of Reactive Oxygen Species
Martin A.A. Schoonen,Corey A. Cohn,Elizabeth J. Roemer,Richard Laffers,Sanford R. Simon,Thomas G. O'Riordan +5 more
TL;DR: This chapter explores the role of minerals in the formation of reactive oxygen species and five different mechanisms by which minerals may promote the formation and transformation of ROS species are explored.

Recycling metals from wastes: a novel application of mechanochemistry.
Quanyin Tan,Jinhui Li +1 more
TL;DR: An overall review of the applications of mechanochemistry to metal recycling from wastes and the reaction mechanisms, equipment used, method procedures, and optimized operating parameters of each case, as well as methods enhancing the activation process are discussed in detail.

Copper and critical metals production from porphyry ores and E-wastes: A review of resource availability, processing/recycling challenges, socio-environmental aspects, and sustainability issues
Carlito Baltazar Tabelin,Ilhwan Park,Theerayut Phengsaart,Sanghee Jeon,Mylah Villacorte-Tabelin,Dennis Alonzo,Kyoungkeun Yoo,Mayumi Ito,Naoki Hiroyoshi +8 more
TL;DR: In this article, a critical analysis of ore distribution/processing, metal extraction, E-waste generation and Ewaste recycling is presented, focusing on identifying challenges and how to address them with emerging technologies and sustainable socio-environmental strategies.
Journal ArticleDOI
Mechanical activation of fly ash and its influence on micro and nano-structural behaviour of resulting geopolymers
TL;DR: In this paper, the authors used fly ash to synthesize geopolymers at ambient temperature and found that the appearance of a new FTIR band in the 1080-1096-cm−1 region in MA fly ash was attributed to SiQn structural units of quartz.

Extractive metallurgy of copper
A.K. Biswas,W.G. Davenport +1 more
TL;DR: Inco flash smelting as discussed by the authors is an outokumpu process that converts matte copper ores into slag and then converts slag to slag-free copper.
