Introduction Accurate prediction of mineral grades is a fundamental step in mineral exploration and resource estimation, which plays a significant role in the economic evaluation of mining projects. Currently available methods are based either on geometrical approaches or geostatistical techniques that often considers the grade as a regionalised variable (Kaplan & Topal, 2020). Geostatistics has […]

Introduction In open pit mining rotary core drilling is the most widely used method of subsurface investigation. For pit slope design, it helps determine within acceptable levels of confidence the geotechnical relationships and engineering properties of the rocks that will form the walls of the pit. Planning and scoping (Guidelines for Open Pit Slope Design […]

President Donald Trump’s vow of tariffs on U.S. copper and aluminium imports would result in higher costs for local consumers because of a shortfall of domestic production and the length of time it would take to renew the industry, analysts and industry participants said on Tuesday. In a speech to Republican lawmakers on Monday, Trump […]

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 […]
