Oct 05, 2020· Evidence of a "leap forward" in metallurgy has been discovered at a 6,500 years old site in Beersheba in the Negev Desert of southern Israel. This story begins in 2017 when archaeologists in Israel excavated 6,500-year-old copper smelting workshops, which were powered with the earliest-known metal furnaces. This kind of advanced metal furnace replaced the use of smaller, more …
Oct 13, 2014· During the copper smelting process, the stack acted as a chimney to carry off the smoke and gases produced as by-products. Exhaust from the individual roasting, smelting and refining furnaces traveled first through a series of dust chambers …
The surprising finds include a small workshop for smelting copper with shards of a furnace – a small installation made of tin in which copper ore was smelted – as well as a lot of copper slag." The furnace may have been invented in the land of Israel, before the birth of the Jewish people.
May 19, 2020· A complex copper dross containing Bi, Pb, Cu, As and Sb was processed in a 3.6 m2 industrial-scale oxygen-rich side-blown bath smelting furnace (OSBF). The products were collected and analyzed by chemical and mineralogical methods. Industrial statistical data showed that recoveries of Cu, Pb, Bi and Sb reached 87%, 96%, 97% and 60%, respectively.

Smelting is a process of applying heat to ore in order to extract a base metal.[1] It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
