  • Net smelter returnQueensMineDesignWiki

    As a result the copper and gold net smelter returns for copper concentrate sold to Smelter A are equal to 511 and 515 per tonne of concentrate or 48.01 and 48.37 per tonne of ore. When these numbers are divided by the mill feed grade the copper and gold NSR factors are equal to 20.69 per Cu and 18.97 per gram of gold.
