Jun 28 2017 most current copper extraction processes burn sulfide minerals in air which produces sulfur dioxide a harmful air pollutant that has to be captured and reprocessed but the new method produces elemental sulfur which can be safely reused for example in fertilizers
If a metal is less reactive than carbon it can be extracted from its compounds by heating with carbon copper is an example of this copper mostly occurs as sulfide ores which are heated in air
The basics of copper mining and processing mined from open pits copper ore must be crushed as part of the process that occurs between extraction and production using todays compact mining equipment copper ore is extracted from the mine after the ore is crushed its roasted which helps to convert sulfides to oxides
Jul 08 2019 mining and extraction of copper by surface or underground methods can concentrate and expose radionuclides in the waste rock and tailings tailings the remaining portion of a metalbearing ore after some or all of a metal such as uranium has been extracted
Crushed copper ore is first typically processed via heap leaching an effective leaching step is critical to sxew as it sets the stage for how much copper can be recovered for this reason the heap leaching step is commonly preceded by agglomeration of the ore in a rotary drum agglomerator

The process ofextracting copperfromcopper orevaries according to the type oforeand the desired purity of the final product each process consists of several steps in which unwanted materials are physically or chemically removed and the concentration ofcopperis progressively increased
Jan 25 2020 the ability toextract copper from orebodies was welldeveloped by 3000 bce and critical to the growing use ofcopperandcopperalloys lake van in presentday armenia was the most likely source ofcopper orefor mesopotamian metalsmiths who used the metal to produce pots trays saucers and drinking vessels
Jan 01 2016 the simplest method ofcopper extractionusing sulfuric acid is applicable only toorescontaining oxidizedcopperminerals such as malachite azurite and chrysocolla generally these processes are uneconomic in treating lowgradecopper ores particularly sulfideores due to the high reagent consumption neutralization required before
Moderncoppersmelters use processedcopper orefed into a flash furnace typically fired by oxygen which produces blistercopper being further processed in a converter furnace moltencopperis poured from here into rectangular moulds the resulting ingots subjected to electrolysis producing a metal of 999 puritycoppercan be recycled indefinitely without the base metal being compromised
