Concern is mounting over just how big a hit the Chinese economy is going to take from the massive tariffs imposed by the United States, but so far the commodity most at risk is seemingly unaffected. Iron ore is the major commodity most exposed to China, given that the world’s second-biggest economy buys more than […]

As the global shift towards renewable energy and electric mobility gains momentum, lithium has emerged as a critical mineral. This lightweight element is a cornerstone in the production of lithium-ion batteries, which power a wide array of modern technologies, from electric vehicles to portable electronics. While lithium mining plays an essential role in supporting clean […]

Introduction   In today’s competitive mining landscape, maximising the efficiency of mobile equipment holds significant value. It’s important to ensure that the equipment is being used as effectively and efficiently as possible, which often involves making operational changes. However, implementing changes to operational procedures often requires a significant investment, making it crucial to demonstrate a […]

Renewable energy is being rapidly adopted by the mining industry in an effort to lower costs and carbon emissions. In order to power operations efficiently, mining companies are looking to solar, wind, and battery storage alternatives as pressure to fulfil sustainability goals increases. Improved environmental performance and less reliance on fuel are two long-term advantages […]

Perth, Western Australia/ April 28, 2025/ Perseus Mining Limited (ASX/TSX: PRU) is pleased to announce that a Final Investment Decision (FID) has been taken to develop the Nyanzaga Gold Project (NGP) in Tanzania, following an update of the NGP Feasibility Study (FS). Perseus has committed to invest approximately US$523 million (including contingency) to develop and prepare […]

Gold gained on Friday as investors rushed to buy the metal a day after its prices hit a two-week low amid receding trade tensions, while the market’s focus shifted to the U.S. non-farm payrolls report due later in the day. Spot gold rose 0.4% to $3,254.51 an ounce, as of 0610 GMT. Gold hit its […]

Analysts in a quarterly Reuters poll have forecast an average annual gold price above $3,000 for the first time, with global trade friction and a swing away from the U.S. dollar powering demand. The poll of 29 analysts and traders returned a median forecast of $3,065 per troy ounce of gold for this year, up […]

Introduction Equipment reliability and maintenance significantly impact mining productivity by directly influencing operational uptime, safety, and costs. Unplanned downtime due to mechanical failures or poor maintenance can lead to substantial financial losses and reduced output. Conversely, proactive strategies enhance equipment longevity, minimize disruptions, and optimize efficiency. This article aims to talk about key impacts and evidence-based […]

Introduction Mining pollution refers to the environmental contamination and degradation caused by the extraction and processing of minerals. One major environmental issue brought on by operations involving the extraction and processing of minerals is mining contamination (comunicación, 2023). Sustainable development objectives call for a considerable reduction in atmospheric pollution, and mining companies are no exception to […]

Introduction Crushing represents a fundamental and often energy-intensive stage within mineral processing and aggregate production circuits (Gawenda & Saramak, 2022). These operations, involving the size reduction of rock, ore, or other raw materials, are critical for preparing materials for subsequent processing steps like screening or grinding, or for producing final aggregate products meeting specific size […]

Indian miner NMDC  is exploring coking coal assets, key ingredient used for making iron ore and steel, in Indonesia and Australia, Chairman Amitava Mukherjee said on Thursday. India, the world’s second-largest producer of crude steel, meets 85% of its coking coal requirements through imports. Australia accounts for more than half of the country’s coking coal imports. […]

Introduction Electronic detonators are advanced initiation devices used to trigger explosives, typically in mining and civil engineering, that utilize electronic circuits and microchips to control the timing and sequence of detonations. Unlike traditional electric and non-electric detonators, they offer precise timing control, enhanced safety, and reduced sensitivity to stray electrical currents, according to the Federal Register […]

Introduction Blasting, the primary method for rock breakage in mining and construction, relies fundamentally on initiation systems to trigger explosive charges. These systems have evolved significantly over time, progressing from rudimentary methods like safety fuses and blasting caps to more sophisticated electric and non-electric detonators. Electric detonators utilize an electric current passed through a resistance […]

What is rock drillability? Drillability of rock refers to the ability of rock to resist pressure and crushing during drilling, it also indicates the efficiency of footage, and it is also an index of rock solidity that indicates the difficulty of drilling blastholes (Alicia, 2023). Drillability, in other words, may be measured by the drilling speed […]
