The screening process serves to separate particles of different sizes and is ideal to ensure that the product reaches the market in the right size, shape and quality. In aggregate production, the screening process is a key part of the production process and is carried out on a large scale. Therefore, it is necessary to […]

This article is issued from (Aguayo et al., 2021). In the classic Shovel-Truck system (without the inclusion of the surge loader) the truck fill factor depends entirely on the shovel and how much material it can load into the truck. This generates three possible scenarios. The first is when the truck exceeds its payload (overfill), […]

This article is taken from (Soofastaei et al., 2018). The rolling resistance (RR) is a major component of total resistance (TR), and it is one of the main controllable effective parameters for haul truck fuel consumption. TR is equal to the sum of RR and grade resistance (GR) when the truck is moving against the […]

Haul truck productivity refers to how efficiently a haul truck transports material from one location to another, typically in an off-highway or industrial setting. It’s measured by the amount of material hauled within a given time, taking into account factors like load capacity, travel time, and efficiency of loading and dumping processes. According to (Soofastaei et al., […]

U.S. President Donald Trump’s threatened tariff on copper imports has generated a mass relocation of physical metal, swamping the U.S. market and draining the rest of the world. Ever since the Trump administration announced a so-called Section 232 investigation into U.S. imports of the red metal in February, traders have been rushing to get metal into […]

Sandfire Resources (ASX:SFR) said assay results from its ongoing drilling program at the MATSA mining hub in Spain confirmed new mineralized extensions at both Magdalena and Aguas Teñidas The firm completed 68 near-mine and resource extension exploration drill holes across the prospects between Oct. 25, 2024, and April 11. Significant assay results were confirmed in […]

Copper prices edged lower on Friday but were set for a weekly rise on China-U.S. temporary trade truce, although uncertainty over longer-term demand prospects for the metal capped further gains. Benchmark copper on the London Metal Exchange (LME) was down 0.4% at $9,536 a metric ton, as of 0707 GMT on Friday. The most-traded copper […]

Overview A mining operation with an extensive road network faced challenges in completing essential road maintenance tasks. Auxiliary fleet utilisation is an important metric to monitor, where efforts should be made to ensure it remains high, especially in challenging climates and geological conditions. At the operation, concerns arose about a potential shortage of road maintenance […]

Regulatory hurdles in Mali have left British miner Kodal Minerals unable to export more than 20,000 metric tons of lithium concentrate, its chief executive Bernard Aylward told Reuters. Kodal’s blocked shipments come as global lithium production is already expected to drop this year – potentially by 228,000 tons – as miners curtail operations due to plummeting prices for […]

One of the first things to recognize in the mining industry, is that all that glitters may not be gold. I’m not talking about the time the CEO of a junior exploration company picked up drill core freshly drilled from the corebox and called a zone of pyrite the best core he’d  ever seen (it […]
