  • The Actual Difference Between Surface and Underground

    Surface mining is commonly used to extract coal and copper, and increasingly, precious metals like gold Underground mining is used for gold, platinum, zinc, lead, and increasingly, coal As can be seen, surface mining is much more advantageous thanof gold production should focus on these two stages Mining and comminution are highly dependent on the grade of gold ore, as the lower the grade, the greater the amount that needs to be mined and the more crushing and grinding is required to extract the gold from the oreThe environmental impact of gold productionMining Methods, Surface mining Depend on wa ter or another liquid (eg, dilute sulfuric acid, weak cyanide solution, or ammonium c arbonate) to e xtract the(PDF) Mining Methods: Part ISurface mining
