The shards of ore harvested from the veins growing in the earth, were brought together and dumped out in a pile on the ground, then raked out and beaten up with hammers. The fragments were inspected in the light of day by miners too old, young, or damaged to go down into the tunnels, and sorted into three piles. The first was stone with no silver in it, which was discarded. The second was ore rich in silver, which went straight to the furnaces to be (if what Jack had seen in the Ore Range was any guide) crushed between millstones, mixed with burning-lead, shoveled into a chimney-like furnace blown by great mule-powered bellows, and melted down into pigs of crude silver. The third, which Jack had not seen at Herr Geidel's mine, was ore that contained silver, but was not as rich as the other. Geidel would have discarded this as not worth the trouble to refine it.
