2024年3月1日 In silver-bearing lead–zinc ore, the dominant mineral compositions are silver, galena, sphalerite and pyrite. In which, the major target minerals recovered as valuable minerals are galena, sphalerite and silver, where silver is usually recovered as an associated mineral along with galena, while pyrite needs to be removed as a hazardous

It has a distinct silver color and a bright metallic luster. Galena tarnishes to a dull gray. Because lead is a primary element in galena, the mineral has a high specific gravity (7.4 to 7.6) that is immediately noticed when picking up even small pieces. Galena is soft with a Mohs hardness of 2.5+ and produces a gray to black streak.

2015年8月5日 All silver ores need to be fluxed for smelting.6 In Pliny's day, when almost all the ore smelted was high-grade, the addition of lead or lead ore (galena, PbS) was sufficient for fluxing (book XXXIII, sec. XXXI). By the time that Biringuccio and Agricola are writing in the 16th century, the art of fluxing has advanced in complexity but not in ...
