One of the most important tasks in underground mining for worker safety and mine stability is scaling, which is the act of removing loose rock from mine walls and ceilings (sometimes referred to as “backs”). Miners and engineers must overcome a number of obstacles in scaling operations despite their significance in order to preserve productivity […]

The Kamoa-Kakula Copper Mine — a joint venture between Ivanhoe Mines (39.6%), Zijin Mining Group (39.6%), Crystal River Global Limited (0.8%) and the Government of the Democratic Republic of Congo (20%) — is a very large, near-surface, flat-lying, stratiform copper deposit with adjacent prospective exploration areas within the Central African Copperbelt, approximately 25 kilometres west […]

Although field-based measurements at individual mine sites are critical methods for assessing site conditions and recovery needs, these methods cannot be applied retrospectively to provide insight into previous site conditions and can be time- and cost-prohibitive when applied across large geographic extents. Remote sensing, however, can provide measurements of past and present surface characteristics and […]

Definition CO2 rock blasting, also known as carbon dioxide rock breaking or gas expansion cracking, is a technique used for rock excavation and breaking in various applications, including mining, quarrying, and construction projects. It is an alternative to traditional methods such as explosives or mechanical methods like drilling and hammering. The following describes how to […]

Gold edged down on Friday and was set for its worst week in more than three years, hurt by a stronger U.S. dollar amid expectations of fewer Federal Reserve rate cuts. Spot gold was down 0.1% at $2,562.61 per ounce, as of 0554 GMT. It has fallen more than 4% so far in the week. […]

Wet scrubbers accomplish particulate collection by employing water or another liquid as the collection media. There are many scrubber designs, but most particulate scrubbers work by creating a wetted target for particle collection. This wetted target plate can be a bed of water or a zone where the particle and water droplet collide. Benefits of […]

French nuclear fuels company Orano warned on Friday of a “deteriorating financial situation” at its Somair uranium plant in Niger, whose board it said had sought a temporary halt on expenditures related to mining and processing ore. Orano owns more than 60% of Somair, while Niger’s state-owned Sopamin holds the rest. Niger is one of […]

Epithermal deposits are types of hydrothermal mineral deposits formed from hot, mineral-rich fluids circulating near the Earth’s surface. They’re important for gold and silver mining because they can contain high concentrations of these precious metals. Epithermal deposits are generally classified into two main types: high-sulfidation (HS) and low-sulfidation (LS). Both types form in volcanic settings, […]

Pulse jet collectors use bags supported from a metal cage fastened onto a tube sheet at the top of the collector as shown in the figure below. Dust-laden air enters the collector and flows from outside to inside the bag. The dust cake deposits on the outside of the bag and is cleaned by short […]
