are cinnabar (HgS), an ore of mercury, sphalerite (ZnS), an ore of zinc, or cassiterite (SnO 2), an ore of tin (Mineral). Part A: The table lists several ores of metals and their chemical formulas. Identify the metal that each mineral ore is a source of by looking at the formula. You can use your ESRT to find the symbol for each element.

Dec 03, 2014· Sphalerite is ZnS (zinc sulfide; dark graycolored). This unusual specimen is from a SEDEX massive sulfide deposit. SEDEX means sedimentary exhalative. The original pyrite and sphalerite (before diagenesis and metamorphism) were marine sedimentary particles in a late Precambrian to Devonian depocenter the Selwyn Basin.

Sphalerite is the most commonly encountered zinc mineral and the world's most important ore of zinc. Dozens of countries have mines that produce sphalerite. Recent top producers include Australia, Bolivia, Canada, China, India, Ireland, Kazakhstan, Mexico, Peru, and the United States.

h) The new collector effectively floats sphalerite (zinc) from a mixed base metal sulfide ore such as a leadzinc or a copperzinc ore without compromising the recovery and grade using only 20% of copper sulfate required for conventional PAX collector in the zincrougher stage.

Sphalerite is the chief ore of zinc, and gem quality specimens are sometimes found in zinc mines. But most sphalerite contains iron, and it is black in color and completely opaque when the iron content is high. The rare gem quality specimens have a low iron content and a high degree of transparency.

Zinc ores . Sphalerite. Sphalerite (see Figure 3), also known as zinc blende, is the lowtemperature (β) form of zinc sulfide (ZnS).It is the chief ore of zinc, occurring worldwide with forms lustrous, cubic system tetrahedral crystals or granular masses.

Sphalerite is a zinc ore and usually also contains some iron. The meaning of its name relates to the Greek word meaning 'treacherous'. This was because it created disappointment among early miners, who found that it often looked similar to Galena, a lead ore, but held no lead.
