We produced magnetite nanoparticles (MNPs) and a Mg-rich solution as a nano-adsorbent and a coagulant for water treatment, respectively, using a low-grade iron ore. The ore was leached with aqueous hydrochloric acid and its impurities were removed by solvent extraction of the leachate using tri-n-butyl phosphate as an extractant. The content of Si and Mg, which inhibit the formation of MNPs.Nov 09, 2019 Extract gold from its ore has a long history in our human history, which can be dating back to sometime around 6000-3000 BC. And we may still remember some notable Gold Rushes in recent centuries In the modern mining industry, washing and extracting gold is not a one-off process.
