Copper (Cu) is used in all electrical and electronic applications, including renewable energy technologies, power grids, electric vehicles, electronic devices, aircrafts and defence technologies. Copper is mined both underground and open-pit and is widely recycled.

Water input in copper mining varies substantially across sites worldwide, with implications for local sustainable resource management. We quantify water use in global copper mining at unprecedented spatial resolution, using machine learning to estimate site-level water withdrawal and identify...

This analysis of intellectual property (IP) protection practices among mining equipment, technology and services suppliers (METS) in Chile's copper mining sector adds to a body of literature that has hitherto focused on high-income countries. It is based on data collated from an online survey of...

China's rapid urbanization and industrialization made it the world's largest refined copper producer and consumer. Insufficient copper ore reserves necessitated significant imports. Using material flow and scenario analysis, this study examined historical copper supply and assessed future...

In this essay, I analyze the nationalization of large copper mines during Salvador Allende's socialist government in Chile in the 1970s. This is one of the earliest cases "nationalization without compensation." Chile's legal argument was based on the novel idea that "adequate" payment should be...

The threat of short-term supply disruptions may matter for commodity prices, although their magnitude is hard to detect, for example, due to anticipation, storage and the relatively short duration of strikes. This article uses a century of labor strikes in Chile copper mines (1910-2010) to...

Evaporation of sessile droplets on hot surfaces is the most important component in spray cooling and other processes. In this paper, the dynamic characteristics of non-boiling evaporation of sessile droplets on the copper surface are obtained by experimental methods under the condition of...

Abstract Background Globally, mining activities have significant environmental impacts after global warming and stratospheric ozone depletion, and one of the most important releasing ways on the environment is anthropogenic activity. The study was aimed at eco-monitoring of the Murgul copper...

Development of an under-liquid super-repellent (ULSR) surface that can be used for separating both liquid/liquid and liquid/gas mixtures is strongly desirable, yet still hard to realize. Herein, to address this challenge, a Cu(OH) 2 nanowire textured surface on copper mesh was developed through...

A weak anion exchange resin (WAER) modified with Cu 2+ ions was prepared and its adsorption behavior for phosphate species in batch and column systems were examined. While pristine WAER adsorbed phosphate species by Bronsted acid-base interaction, the Cu-WAER captured phosphate species mainly...

Negative permittivity is a required physical property of metamaterials which has been widely used in some emerging and unconventional applications, such as cloaking, perfect lens and perfect wave absorption. In addition to periodic meta-structured units, a composite with conductive networks,...

Copper sulfides (Cu x S) have been considered as candidates for sodium ion battery (SIB) anodes because they are environmentally friendly and have large theoretical capacity. Whereas, the cycle stability and capacity of Cu x S are still challenge for their practical applications. Here,...

In this work, we highlights 5G antenna (~ 28GHz) using Al 2 O 3 -doped CaO-MgO-SiO 2 glass ceramics with reducing-resistant behavior co-fired with copper electrode. The diffusion behavior between copper electrode and low-temperature-co-fired-ceramics (LTCC) were also studied. Amphoteric Al 3+...

In 1611, the seventeen-year-old Gustav Adolf ascended the throne of Sweden. Before the new king could sit on his throne, however, he faced a disastrous war against Denmark, another conflict in Russia, and a rebellious nobility at home. Plus, Sweden itself had an arctic climate and a short...

Antofagasta is a world leader in copper and lithium production, with strategic importance for the global energy transition and for the economic development of Chile. Located in north Chile, Antofagasta is carved by the natural contours of the Atacama Desert and home to diverse Indigenous...
