    Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production). Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were treated by smelting. Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters

    OverviewProcessHistoryBase metalsEnvironmental implicationsSee alsoBibliography

    Smelting is a process of applying heat to ore in order to extract a base metal. 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. The reducing agent is commonly a source of carbon, such as coke—or, in earlier times, charcoal.

  • Copper processing - Ores Britannica

    Copper processing - Copper processing - Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

  • 60 Centuries of Copper: Early Smelting Practice

    Early Smelting Practice. Virtually all the ore used by the ancients was handpicked with only the most worthwhile material being taken.

  • Copper Smelting Chemistry Tutorial

    A typical copper ore contains between 0.5% and 2.0% 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 5000 BC.

  • What Is Copper Smelting? (with pictures)

    2019-12-06  Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.
