Sep 23, 2013· Selling Metal Concentrates: Payable Metal, Treatment Charges, Penalties, Terms of Sale. First there is a deduction from the contained metal assay to compensate the smelter for processing metal losses. If the concentrate grades around 50% lead and 20% zinc, then around 3% of the lead and 8% of the zinc will be deducted. This is effectively part of the treatment fee and is usually higher for lower .

There was also found a mining shaft and numerous furnaces in the settlement area, confirming its mining and metallurgical character. The settlement development was based on excavating and smelting rich lead ores, containing significant amount of silver. Silver was separated from lead in successive stages with the help of cupellation.
