Sulfide Mining Mining Methods Techniques Copper Zinc Smelting and Roasting Ores to recover gold silver and

Sulfide Mining Mining is the method of tacking materials from the earth to get valuable metal ores like copper zinc and lead which are known as target minerals in mining termsThis is a concern because Arsenic is actually very common in many gold or Selenium mercury and other toxic elements are also found in many high sulfide gold and silver ores as well To roast sulfide ores it takes a good red heat and a good amount of air but not too hot as you don t want to melt them
