The zinc mining process is conducted primarily underground, with more than 80 percent of all zinc extracted beneath the Earth's surface. Eight percent of zinc is mined in open pits, with the remaining 12 percent being mined through both methods.
The facility uses the RLE process for zinc production. Hobart's key products are SHG zinc, die cast alloys (branded 'EZDA') and CGG (continuous galvanising grade) alloys. In addition, the site produces byproducts of cadmium, copper sulphate, paragoethite, lead sulphate, leach concentrate and sulphuric acid.
Germanium is a semiconductor metal and a rare element in the crust (average: ppm). It is an important hightechnology electronic metal, finding increasing use in fiber (50 %) and infrared optics (15 %), and as polymerization catalysts (20 %; BROWN, 2000).
The zone melting process developed by William Gardner Pfann was used to produce pure germanium, and subsequently floatzone silicon became available when Henry Theuerer of Bell Labs adapted Pfann's method to silicon. Types of materials that are usually refined: metals see Refining (metallurgy) petroleum; silicon; sugar; flour; table salt; vegetable oil; air; glass
FieldCore is committed to providing World Class execution to support GE across all major service lines, including oil gas.

Sources. The element is commercially obtained from the dust from smelters that process zinc ores. It is also recovered from combustion byproducts of certain coals. Germanium can be separated from other metals by fractional distillation of its volatile tetrachloride. These techniques permit the production of germanium of ultrahigh purity.
Germanium in the environment. Germanium is less abundant than either tin or lead, which are the heavier component metals of group 14, and it is less easily accessed because geological processes have contracted only small amounts of it into minerals, so that it tends to .
Germanium is mainly a byproduct of zinc ore is a hard, grayishwhite element; it has a metallic luster and the same crystal structure as is stable in air and water, and is unaffected by alkalis and acids, except nitric is an important semiconductor, mainly used in transistors and integrated circuits.
Germanium button. Description supplied by the source: This germanium button was melted from standard 5N+ pure melt stock in an vacuum arc melter the germanium and surrounding crucible were heated much more than was necessary to melt the small blob, so that the rate of heat loss was slower and greater crystalline structure had time to develop.

Usually, beneficiation of rare earth elements adopts the technological process known as the flotation method and is often accompanied by various combinations of gravity separation and magnetic separation.
To do so the ore is crushed to fine particles and subjected to the following methods of concentration: Hydraulic washing; Magnetic Separation; Froth flotation method; Hydraulic washing. Hydraulic washing is done with an upward flow of water. In this process lighter gangue particles are washed away leaving behind the desired heavy are particles.
