This doesn't mean that it's all doom and gloom for mining companies; they're a resourceful and innovative bunch, that constantly push for better solutions. We'll list some of the challenges the mining sector faces …
Highly efficient gold extraction by rGO. The rGO was obtained by chemical reduction of commercial, mass-produced graphene oxide (GO) nanosheets using ascorbic acid as a reductant (Methods).
The long-term availability of lithium in the event of significant demand growth of rechargeable lithium-ion batteries is important to assess. Here the authors assess lithium demand and supply ...
This guideline project, a revision of the suite of guidelines originally published in 2017 and 2019, aims to provide a high-level overview of the processes needed by mine …
To move materials around a mine site, workers need heavy-duty trucks. Also known as off-highway trucks, large mining trucks include both powerful mechanical models and environmentally friendly electric drive models.. Unlike conventional trucks, these mining vehicles have extra-large tires to support the heavy loads over uneven terrain commonly found around …
Communications in underground mines include bus communication, wired telephone communication, industrial Ethernet communication, and wireless communication. Bus …
Microbes are playing increasingly important roles in commercial mining operations, where they are being used in the "bioleaching" of copper, uranium, and gold ores. Direct leaching is when ...
Wireless communication technologies in mining will have a significant impact on mine operations in the coming decades, giving mine managers and staff much greater understanding and control over mining …
Underground mines are GPS-denied and extremely challenging environments, both from an environmental hazard as well as from a wireless communications standpoint. Inertial measurement unit (IMU) measurements used in dead reckoning algorithms quickly accrue heading drift errors and are unsuitable for large scale environments. By dividing up the …
There are two basic classes of mining: mining at the Earth's surface and mining underground…Surface mining accounts for two thirds of the world's solid minerals, and is predominantly used in obtaining sand, gravel, crushed …
The silvery blue metal is used to make lithium-ion batteries that supply energy to everything from cars to e-cigarettes. It's also toxic and mined in Congo—where thousands of workers toil in ...

The production of lithium compounds is becoming increasingly important in producing lithium-ion batteries for use in consumer electronics, electric vehicles, and other energy storage ...
Direct sourcing from mining companies allows Tesla to engage directly in local contexts instead of having to rely on multiple midstream companies that typically sit between EV makers and mining.
Lithium-ion batteries, LIBs are ubiquitous through mobile phones, tablets, laptop computers and many other consumer electronic devices. Their increasing demand, mainly driven by the implementation of the electric vehicles, brings several environmental issues related to the mining, extraction and purification of scarce materials such as cobalt, nickel and lithium.
The energy used by mining machinery creates climate pollution like carbon dioxide, which warms the planet. A 2021 study found that lithium concentration and production from brine can create about 11 tons of carbon dioxide per ton of lithium, while mining lithium from spodumene ore releases about 37 tons of CO 2 per ton of lithium produced. 5

Battery technology for mining . Also sold in South Africa are the products manufactured by First National Battery, which made its first batteries in 1931. More particularly, the range of batteries can be used with automotive starters, mining traction and materials handling machinery, and miners cap lamps, and for solar power storage.
Ion Cubes are a piece of technology created by the Precursors. They can contain massive amounts of energy equivalent to a 'small nuclear detonation' in a stable state. Ion Cubes are used to power certain Precursor devices, such as Alien Arches, which will only function once an Ion Cube has been inserted. They can be used to craft Alien Tablets, as well as powerful Ion …
Conventional two-way radios, adapted for use in mines, can be used over limited distances (generally line of site or close to it), and are commonly used for communication with drift transports and more frequently now being used by such people as surveyors, personnel installing major items, shaft top to bottom, etc.
