Chemistry Tutorial Copper Smelting AUS e TUTENational Inventory of Sources and Emissions Selenium

A typical copper ore contains between 05 and 20 copper A high grade ore produces a high yield of metal A low grade order produces a low yield of metal Copper can be extracted from sulfide ores usually higher grade ores by direct smelting The earliest evidence of copper smelting occurs in Serbian artefacts dating from around BCIn order to identify the sources of emissions to the atmos phere during the recovery of selenium it is necessary to start with the copper ore then trace the selenium through copper smelting electrolytic copper refining and precious metal recovery

Arsenic and selenium in lung liver and kidney tissue Emission Estimation Technique Manual

Concentrations of arsenic and selenium in lung liver and kidney tissue from dead smelter workers and from a control group have been determined with the aid of neutron activation analysis A sevenfold increase of arsenic was found in lung tissue from the exposed workers compared with the control groupthe delivery of ore to the processing facilities through to smelting and the production of 99 pure lead at the refinery It also covers operations that produce lead concentrates only and the smelting of lead from imported concentrat This manual does not include extraction of ore which is covered by the EET Manual for Mining

Smelting WikipediaUtah APPLETREE Document Archive

Smelting is a process of applying heat to ore in order to extract a base metalIt is a form of extractive metallurgyIt is used to extract many metals from their ores including silver iron copper and other base metalsSmelting uses heat and a chemical reducing agent to decompose the ore driving off other elements as gases or slag and leaving the metal base behindLHC Letter Health Consultation A letter health consultation is a health consultation addressed to a specific audience using an abbreviated letter format They are used in response to a specific public health issue or question usually a single exposure pathway and provide a timely and more focused response
