<p>[QUOTE=&quot;GeorgeM, post: 1093999, member: 28550&quot;]That&#039;s the cost for miners to smelt Silver ore (40 cents per ounce). I&#039;m not entirely sure on it either; obviously lower grade ore would be costlier to smelt than high grade ore, and that number is from just one source.</p><p><br /></p><p>Anyone have a mining or geology background who can help me firm up that number? 5 tons of waste soil per ounce was stated on numerous articles, but I couldn&#039;t find info on energy consumption. What&#039;s the energy use and how much air pollution is produced per ounce of refined silver?[/QUOTE]</p><p><br /></p>
