  • How is Silver Mined APMEX

    Silver is separated from this ore using a chemical process known as smelting. To begin a new Silver mine, a system of multi-layered crosscuts are made. Each cut connects to a central shaft but is kept at a safe vertical distance to avoid collapses. Openings called raises are dug to connect each level.Lead and Zinc Energy,Treatment of lead and zinc ores begins with milling. Milling is a multi-stage crushing and grinding operation.
