Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.
Quartz; Topaz; Corundum; Diamond; Streak is the mark some minerals leave on an unglazed porcelain plate. Minerals with a hardness of less than about 7 will leave a streak on the plate. The color of a streak, which can be a different color than the mineral, helps identify the mineral. Galena, which is lead gray, leaves a lead gray to black streak.
The most common gangue minerals are quartz, calcite, and dolomite. Rhodochrosite and rhodonite are abundant in zinc ores at Butte, Montana. In some deposits the heavy silicates, such as garnet and actinolite, are intergrown with sulphides of zinc and lead.
The Si-O-Si bond linking two tetrahedra is not straight (180°), but forms an angle of 144° in quartz (Fig.5). As a result, the overall crystal structure of quartz is quite complex. In other silica modifications this angle is different, while the angles inside the SiO 4 tetrahedra (defined by the O-Si-O bond) remain basically the same. The following table lists angles and distances for a few ...
The most common gangue minerals are quartz, calcite, and dolomite. Rhodochrosite and rhodonite are abundant in zinc ores at Butte, Montana. In some deposits the heavy silicates, such as garnet and actinolite, are intergrown with sulphides of zinc and lead. Goslarite occurs on the walls of some mine workings as a white efflorescence.
The deposit contains polymetallic silver, lead and zinc vein-type mineralisation. Silver, lead and zinc minerals are largely accumulated within well structured rocks including the Central quartzite. Gangue minerals within the deposit include trace amounts of calcite, manganiferous siderite and quartz.

Feb 10, 2010· Thereafter, lead-silver ores were mined and subsequent improvement in milling led to exploitation of complex lead-zinc ores. Zinc-lead mining reached a peak from 1915 through 1917 owing to high metal prices during World War I. Production declined abruptly after 1917, and thereafter mining was confined to veins with relatively high gold content.

Native Lead is a very rare mineral, with few noteworthy localities. Perhaps the best collectors specimens come from Langban, Sweden. The Harstigen Mine in Varmland, Sweden has also produced a limited amount of Lead, and it has also recently been found in the Garpenberg Noora Mine, also in
Sedimentary exhalative deposits (SedEx or SEDEX deposits) are zinc-lead deposits originally interpreted to have been formed by discharge of metal-bearing basinal fluids onto the seaflor resulting in the precipitation of mainly stratiform ore, often with thin laminations of sulphide minerals. SEDEX deposits are hosted largely by clastic rocks deposited in intracontinental rifts or failed rift ...
