This article was written by (Gandhi & Sarkar, 2016) Sampling is subject to certain limitations due to two types of errors: (1) random and (2) systematic. The random errors tend to cancel out each other, whereas the systematic error accumulates to create gross errors, which are easily recognizable because of their magnitude. The errors may […]

The over-reliance on concentrated supply chains for key minerals is a major issue in the current global energy transition, according to Oryx Global Partners’ most recent paper, The Need for key Minerals Supply Chain Diversification. 90% of rare earths, more than 50% of nickel, lithium, and cobalt, and 95% of battery-grade graphite are processed and […]

Gold prices soared to near three-month highs on Wednesday, trading just below its record peak, fuelled by a soft dollar and lack of clarity around U.S. President Donald Trump’s policy plans, which investors fear could trigger trade wars and elevate market volatility. Spot gold added 0.4% to $2,755.2 per ounce as of January 22, 02:29 […]

Indonesia’s parliament proposed on Thursday to revise the country’s mining law to help the government accelerate development of its mineral processing industry and to regulate mining permits for religious groups and for universities. President Prabowo Subianto has vowed to expedite development of Indonesia’s mineral processing industry and energy transition and formed a special task force […]

Overview Flotation is the most flexible and adaptable mineral beneficiation technique. Mineral separation by flotation works on physicochemical surface properties of valuable and unwanted gangue minerals. It is being continuously modified for low-grade complex sulfide ores like lead-zinc, leadzinc-copper, nickel-platinum-gold, tin, fluorite, phosphate, fine coal and iron ore at a lower cost with better recovery. […]

Zambia’s copper output rose 12% in 2024, buoyed by a recovery in production at key mines as the government counts on the sector to drive economic growth. Output reached roughly 820,670 metric tons, up from 732,580 tons the year before, Mines Minister Paul Kabuswe said on Wednesday. Barrick Gold’s (ABX.TO), opens new tab Lumwana mine ramped up output and Vedanta […]

This article was written by https://www.monash.edu/ Australia risks losing its world-leading advantage in critical and rare minerals used for clean energy, electric vehicles and batteries for solar energy, unless it embraces artificial intelligence in the mining sector, according to research from Monash University and the University of Tasmania. In a paper published in Nature Communications, the researchers […]

Greenfields exploration is normally conceptual, relying on the predictive power of the ore genesis models, to search for the mineral resource in an unexplored virgin ground. Brownfields exploration is conducted within geological terrains which are closer to known ore deposits. Brownfields is less risky, as the geology is better understood and the exploration methodology is […]

Introduction The excavation or drilling in rocks becomes extremely complicated when working in confined spaces and if you need to drill holes with large diameters. Often the length and diameter of these perforations becomes impracticable due to the cost of time and labor. In view of these problems, a simple, compact and really solution was […]

The Tau Tona Gold mine in South Africa was extended to a depth of 3.9km in 2008, making it the world’s deepest mine at that time. The name TauTona means ‘great lion’ in Setswana (“TauTona Gold Mine, Anglo Gold, South Africa,” n.d.). The mine was located at on the West Wits line, south of Carletonville, […]
