lead ore smelting method

LEAD AND ZINC PRODUCTION The Handbook of Texas

In 1901 and 1902 a small smelter at Shafter produced lead from ore obtained at the Chinati Mine in Presidio County. Between 1911 and 1917 mines in the Trans-Pecos produced small quantities of zinc, and in 1915 and 1916 there was some lead production in connection with silver in that region.

Carbon Reduction Method for Extracting Metals AUS

Concentrating the ore by froth flotation increases the percentage of lead in the ore by removing many of the minerals that do not contain lead. A collector oil, such as an organic xanthate or thiophosphate, is added to the powdered ore and adheres strongly to the cerussite particles making them water repellant.

Lead Bronze . Mixing lead into the copper-tin alloy produces lead bronze, which may contain as much as 10% lead. The lead in the alloy does not become part of its crystalline structure, increasing the fluidity of compound when it is in its molten state. This facilitates casting, particularly the casting of finely detailed artistic objects. However lead bronze is softer than normal bronze, and therefore less able to hold a
