"The Yellow Pine mine at Goodsprings, in southwestern Nevada, yields an ore nearly free from gangue constituents. The ore as mined contains 8 to 12 per cent lead, 8 to 12 ounces silver, and 30 to 35 per cent zinc, and is milled in a gravity concentration plant where separation of the lead and zinc is made. The ore is nearly all carbonate, except a small amount of galena, and the lead concentrates contain considerable zinc; the zinc concentrates contain lead and silver in quantities ranging from 3 to 7 pr cent and 3 to 7 ounces, respectively, The lead and silver in the zinc concentrate is a total loss, as well as an expense; on a bases of 35 to 50 tons per day the loss becomes serious. The following tests were made with the object of recovering this lead and silver"--pages 1-2.
