Eureka and its resources; a complete history of Eureka County, Nevada, containing the United States mining laws, the mining laws of the district, bullion product and other statistics for 1878, and a list of county officers . herefor there has been extracted andreduced, in less than seven years, over $20,000,000; and min-ing in Eureka is yet in its infancy. Not only are new minesbeing continually opened, but in all the mines increasedproduction follows an increase of depth, and not even in theoldest mines has great depth yet been attained. The historyof Eureka lies in its future. The sixteen furnaces in the neighborhood of the town andtheir capacities are as follows: Eureka Consolidated, 5 fur-naces, 300 tons; Richmond Consolidated, (limited), of London^6 furnaces, 360 tons; Atlas, 2 furnaces, 120 tons; Hoosac, 1furnace, 50 tons; K. K. Consc^lidated, 1 furnace, 50 tons;Matamoras, 1 furnace, 45 tons; total daily smelting capacity,925 tons. The cost of smelting (running two or more fur-naces) has been $13 per ton, and about 85 per cent, of theprecious metal is saved, when the charge is properly fluxed. The following article illustrates the modus operandi of thetreatment of the ores peculiar to this district:. A PRIMITIVE a Sketch hv K. C. Rdbhins EUREKA AND ITS RESOURCES. 29 TREATMENT OF ORES MINED IN EUREKA John A. Porter, M. E. (Supt. K. K. M. Co.) All ores mined in Eureka district are taken to the town ofEureka for metallurgical treatment. A branch of the Eureka and Palisade railroad furnishes ameans of transportation for the mines of Ruby HiU, whileores from other parts of the district are conveyed to the fur-naces by wagon, and in some cases by pack traia. Smelting in the lead blast furnace has been found by farthe most profitable means of working Eureka ores. Themethod employed is technically termed the Iron Reductionprocess. Ruby Hill furnishes ninety-nine per cent, of all orestreated, which, from their chemical composition, admit ofdirec
