text: The value of the pyrite in gold and silver plays an important part in the determination of the process to be followed; if its value is negligible, then any loss of blende in the nonmagnetic tailing merely results in a decrease in the percentage recovery of the zinc; but if the pyrite is valuable for contained gold and silver, this nonmagnetic tailing should be kept below the zinc penalty limit set by the lead smelters to which this product is destined.
