  • Nickel sap hypoaccumulators agromining phytomining Malaysia Borneo

    Tapping nickel syrup from Borneo trees

    Shane Lasley, Metal Tech News|Updated Jun 8, 2023

    Could we mine the nickel we need for lithium-ion batteries, stainless steel and other applications in much the same way as we make pure maple syrup – from the sap of trees? Research at one nickel syrup agromining grove in Malaysia is demonstrating that this concept is not as far-fetched as it might sound. While most of Earth's flora tend to avoid the sulfide-rich and potassium-poor ultramafic deposits that host much of the world's nickel – geologists often use sparse veg... Full story
