  • The Mining Milling ProcessThe Piedmont Environmental

    Milling. Uranium milling involves extracting uranium from mined ore. The ore is crushed into sand size particles and the uranium is leached out. The uranium then is precipitated out of the leaching solution and dewatered dried and packaged. Through the extraction process uranium is concentrated into a product referred to as "yellowcake."

  • How Is Gold Processed Reference

    Gold is processed by cyanide milling a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity according to Mineweb. Heap leaching is a less expensive method of gold extraction but it is a longer process and it recovers less gold than the cyanide milling process.
