    May 26 2009· The second reson that a gold mine has to control the grade is that the milling process is usually designed to be most efficient at a certain grade. When mining a high grade zone some of the gold may be lost and end up in the tailings unless the high grade ore is blended with low grade material to provide the mill with a grade that it can handle.
