Wet, clumpy or poorly liberated material needs another step first.<\/p><\/details>\r\n<details><summary>When should I choose one stage or multiple stages?<\/summary><p>Use one stage when one pass reaches the required result without excessive good-material loss. Add a stage when one pass cannot protect both product quality and recovery.<\/p><\/details>\r\n<details><summary>Can a magnetic roller separator remove iron from silica, quartz or feldspar?<\/summary><p>Yes, when the iron-bearing particles respond to the magnetic field and are already separate from the valuable mineral. If they are still locked inside the particle, improve liberation first.<\/p><\/details>\r\n<details><summary>What if my feed contains moisture?<\/summary><p>Dry or condition the feed first if moisture makes particles stick together or causes unstable feeding. A stronger magnetic field does not fix clumps or an uneven feed layer.<\/p><\/details>\r\n<details><summary>What if the iron-bearing mineral is not liberated?<\/summary><p>Free the iron-bearing mineral first. If iron and the valuable mineral are still locked in the same particle, the magnet cannot separate them; this is poor mineral liberation.<\/p><\/details>\r\n<details><summary>How do feed rate and roll speed affect separation?<\/summary><p>A higher feed rate can make the layer too deep and hide weakly magnetic particles. Roll or belt speed changes the particle path and time near the magnetic roll.<\/p><\/details>\r\n<details><summary>How should the splitter be set?<\/summary><p>Set the splitter between the product paths. Moving it can improve purity but may also increase good-material loss, so check both purity and recovery.<\/p><\/details>\r\n<details><summary>Does higher Gauss mean higher recovery?<\/summary><p>No. Gauss is magnetic flux density at a specific point.
