prehistoric technology is technology that predates recorded history.history is the study of the past using written records. anything prior to the first written accounts of history is prehistoric, including earlier technologies.about 2.5 million years before writing was developed, technology began with the earliest hominids who used stone tools, which they may have used to start fires, hunt .
metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are called alloys.metallurgy is used to separate metals from their ore. metallurgy is also the technology of metals: the way in which science is applied to the production of metals, and the engineering of .
experimental archaeometallurgy is a subset of experimental archaeology that specifically involves past metallurgical processes most commonly involving the replication of copper and iron objects as well as testing the methodology behind the production of ancient metals and metal objects. metals and elements used primarily as alloying materials, such as tin, lead, and arsenic, are also a part of .
certain metals, notably tin, lead, and at a higher temperature, copper, can be recovered from their ores by simply heating the rocks in a fire or blast furnace, a process known as smelting. the first evidence of this extractive metallurgy, dating from the 5th and 6th millennia bc, 8 has been found at archaeological sites in majdanpek , jarmovac near priboj and pločnik , in present-day serbia .

total crap the first version of this article was called copper extraction from chalcopyrite. it was created by 126.96.36.199 talk · contribs on 16 july 2004 and expanded by svenny talk · contribs a few weeks later. after some copyediting and wikifying the article reached it peak in this version on 11 march 2005.
the history of technology is the history of the invention of tools and techniques and is one of the categories of the history of humanity.technology can refer to methods ranging from as simple as stone tools to the complex genetic engineering and information technology that has emerged since the 1980s. the term technology comes from the greek word techne, meaning art and craft, and the word .
native copper does not naturally occur in large amounts, but copper ores are quite common and some of them produce metal easily when burned in wood or charcoal fires. eventually, the working of metals led to the discovery of alloys such as bronze and brass about 4000 bce . the first uses of iron alloys such as steel dates to around 1800 bce.
furthermore, grinding the frit actually expedites the “second part of the process, which is to…reduce the system to a glass.” moorey has defined this intermediate step as “fritting,” “a process in which the soluble salts are made insoluble by breaking down the carbonates, etc. and forming a complex mass of sintered silicates.”
the local copper ores often occur together with gold and silver. the gold must have been obtained, both by the washing gravel method in the valleys rich with such ores, as well as through mining the gold ore on the surface, or in shallow veins in ravines or landslides.
