It is a hard gray-white substance that is found in zinc silver lead and copper ores A German chemist called Clemens Winkler discovered the element in 1886 and named it after Germany The main production of germanium is as a byproduct from zinc ore and there is over 100 tonnes produced each year It is highly sought-after for its important Residues from zinc concentrates were treated in roasters or pressure-leach facilities and purified to produce germanium dioxide germanium tetrachloride and other byproduct metals Teck reported that zinc-in-concentrate production at Red Dog in 2014 was 596 000 metric tons (t) 8% more than that of 2013 owing to increased mill throughput and

processing zinc ore germanium

Most germanium is recovered as a byproduct of zinc smelting although it also has been recovered at then processed in the same way as ore concentrates Read More Processing of indium: a review Indium is an important by-product of zinc metal processing operations

Additionally a zinc smelter in Tennessee produces and exports germanium leach concentrates produced from nearby zinc mines Optical indium Indium has a lot in common with germanium – it has strong optical qualities is used in higher efficiency solar panels and is often recovered as a byproduct from zinc mining

Germanium is a fairly rare element that is found in the Earth's crust Although there are some minerals that contain a fair amount of germanium like germanite and argyrodite they are too rare to be mined The majority of germanium that is used by industry is produced as a byproduct of mining sphalerite zinc ore where it is found in small traces

germanium - USGS Mineral Resources Program The company continues to produce germanium-rich residues as a byproduct of processing zinc ores from its Gordonsville Mine Therefore much lead ore is obtained as a byproduct of other metal mining usually zinc or silver

USGS: Statistics and Information: Germanium

Germanium is mainly a byproduct of zinc ore processing It is a hard grayish-white element it has a metallic luster and the same crystal structure as diamond and it is brittle like glass In addition it is important to note that germanium is a semiconductor with electrical properties between those of a metal and an insulator The

Rare Earths belong to minor metals too China is main source of various rare earths The first reserves of indium is in China which take 90% of worldwide supplies Indium is mainly used in display LCD FPD low-melting-point alloys solder semiconductors and vacuum coating It is mainly from byproduct of lead zinc ore

In 1998 the domestic germanium industry consisted of two zinc mining operations in Alaska and Tennessee which supplied byproduct germanium concentrates to the export market and three refineries in New York Oklahoma and Pennsylvania In January 1998 Eagle-Picher Industries Inc the largest domestic germanium producer was bought by

and carbonate-hosted Kipushi-type (KPT) zinc-lead-copper deposits Germanium is primarily recovered as a byproduct from zinc silver lead and copper ores from these deposits but world-wide production is dominantly from the zinc ore mineral sphalerite (zinc sulfide) Because metallurgical operations are commonly fed by concen-

NightHawk Solutions asks you to consider recycling your germanium refuse items broken optics technology wastes and liquids We work with germanium as low as 2% content solutions and compounds to give a second life to germanium products You are welcome to contact us with any requests and concerns related to the recycling of germanium

Mineral Commodity Profiles: Germanium Published 2005 By W C Butterman and John D Jorgenson Introduction Germanium is a hard brittle semimetal that first came into use a half-century ago as a semiconductor material in radar units and as the material from which the first transistor was made

03/04/2015In the case of indium for instance typical concentrations in the zinc host ore are only a few parts per million too low to mine for indium itself Thus nearly all indium production occurs as a by-product of zinc (with much smaller amounts from tin and copper ores also as a by-product) In contrast silver sometimes has deposits that are
