Sphalerite mineral is in group of Sulfide mineral that is formula ( (Zn, Fe)S).It is the principal ore of zinc. Pure sphalerite is colorless and rare. Normally, iron is present, causing the color to vary from pale greenish yellow to brown and black with increasing iron content. When iron content is high it is an opaque black variety, marmatite.

6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Zinc Mining. The most commonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide (ZnS). Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas.

Zinc is one of the most common elements in the earth's crust. It is found in air, soil, and water, and is present in all foods.Pure zinc is a bluish-white shiny metal. Zinc has many commercial uses as coatings to prevent rust, in dry cell batteries, and mixed with other metals to make alloys like brass, and bronze. A zinc and copper alloy is used to make pennies in the United States.

Zinc oxide is prepared commercially by two methods: the American (or direct) process, which uses zinc ore and concentrate, and the French (or indirect) process, which uses zinc metal. Some 54% of US zinc oxide production is from zinc ore and concentrate (American process), 33% from slab zinc (French process) and 13% from secondary material.

About two thousand years ago, emissions of zinc from mining and smelting totaled 10 thousand tonnes a year. After increasing 10-fold from 1850, zinc emissions peaked at 3.4 million tonnes per year in the 1980s and declined to 2.7 million tonnes in the 1990s, although a 2005 study of the Arctic troposphere found that the concentrations there did not reflect the decline.

History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.

Zinc metal is produced using extractive metallurgy. The ore is finely ground, then put through froth flotation to separate minerals from gangue (on the property of hydrophobicity), to get a zinc sulfide ore concentrate consisting of about 50% zinc, 32% sulfur, 13% iron, and 5% SiO 2.

Metal­lic zinc is a sil­very-gray met­al with a melt­ing tem­per­a­ture of around 419.5 °C (787.2 de­grees °F). At 100 °C (or 212 °F), the met­al is mal­leable. It is rather brit­tle at room tem­per­a­ture. Metal­lic zinc is ob­tained from en­riched ore (usu­al­ly spha­lerite ZnS is used for these pur­pos­es).

Sphalerite ore, also known as blackjack, ruby blende, and zinc blende is a mineral and ore of zinc with a chemical composition of ((Zn, Fe)S). It was discovered by Ernst Friedrich Glocker in 1847, who named it based on the Greek word "sphaleros" meaning deceiving or treacherous because its lustrous dark crystals can be misguided for other minerals.
