why does purifying the copper ore produce waste? Yahoo

May 15, 2011 · Also remember that all metal ore processing produces waste. You might like to check the percentage of copper in a typical ore (if its 20%, then what is the rest of it?). Just by the way, since gold often occurs in the same ore as copper, a tonne of ore may contain as little as 5 grams of gold.

Mining Water for all

Mining produces mainly tailings (the waste materials left after the valuable ore is separated out) and overburden (the waste materials removed to reach the ore). During the mining process, water within and around the mine is usually contaminated, so treating the mine water before it is discharged back into the environment is a major issue [2].
