    Trolley lowers Baptiste nickel CO2 intensity

    Shane Lasley, Metal Tech News|Updated Aug 13, 2024

    Study shows that trolley assist for trucks would halve CO2 intensity of what is expected to be one of the world's cleanest sources of nickel. A recently completed engineering study has found that a trolley assist system for haul trucks would significantly reduce the carbon intensity of nickel produced at Baptiste, a project in central British Columbia being advanced by FPX Nickel Corp. that is already shaping up to be one of the cleanest sources of future nickel on the...

    Three positive trends in critical minerals

    K. Warner, Metal Tech News|Updated Jul 11, 2024

    Reports demonstrate how growing demand, international cooperation, and social change are shaping the mining sector for the better. The continuing surge in critical minerals demand, anticipated to easily double by 2040, has significantly impacted the global mining sector while several world powers struggle to slip out from under geopolitical pressures on the battery industry and develop domestic supply chains. Propelled by technological expansion, the rate of demand growth for...

    Gamblin Artists Colors introduces oil paints pigmented with waste from acidic water draining from old coal mine. Paints throughout the ages have been uniquely colored by crushed gemstones, rare shellfish, and even powdered Egyptian mummies. With that same pioneering spirit, the Portland, Oregon-based Gamblin Artists Colors began recycling dry pigment dust collected by their Torit air filtration system during the 1990s and mixing it into a paint color they called Torrit Grey....

    Apple, USGS develop rock-to-metal ratio

    Shane Lasley, Metal Tech News|Updated Jul 12, 2022

    How much rock must be moved to produce the metals in an Apple iPhone, Tesla Model 3 electric vehicle or any other product that requires mined commodities (i.e., nearly everything)? Apple teamed up with the United States Geological Survey to develop a "rock-to-metal ratio" that makes it easier to answer that question. Metals are essential to every aspect of modern life. Even a bowl of oatmeal requires these fundamental building materials to grow, ship, and process this...
