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 […]

Gold fell for a fifth straight session on Thursday to hit its lowest level in eight weeks, pressured by a stronger U.S. dollar and rising Treasury yields amid uncertainty over the pace of the Federal Reserve’s interest rate cuts. Spot gold was down 0.7% at $2,555.85 per ounce as of 0744 GMT, after hitting its […]

Introduction Screening operations can produce high levels of dust because smaller-sized material is handled. Airborne dust is generated from the vibrating screen decks that accomplish the size separation. Additionally, material must fall some distance as part of the separation process, and some dust will be suspended by this process. Dust control for screening Dust control […]
