Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SX/EW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20% of all copper produced is produced by this is process.

The oxide mineralized material will be processed via a cyanidation leach circuit to produce doré. Depending on the grades of copper, zinc and lead, the sulphide mineralized material will be processed via two stages of flotation to produce concentrates, i.e. either a copper and zinc concentrate, or a lead and zinc concentrate.
The 60,000 st/d processing plant will utilize three stages of crushing (gyratory, cone and HPGR crushing), ball mill grinding, and conventional flotation to produce a high-grade copper concentrate with associated precious metal credits. The processing plant will operate in two 12 h shifts per day, 365 d/a.

DYNAFIN 520 L is a single liquid concentrate that is diluted with water to produce ablack oxide finish on copper and copper alloys.The coatings produced with DYNAFIN 520 L are jet-black, adherent, chemically and heat stable to a temperature of 400F.Applying oil, wax or a lacquer will help enhance the corrosion protection.
May 01, 1984· The copper metallurgi- cal process adopted consists of smelting of copper concentrates in a closed- roof blast furnace, followed by blowing in a converter and electrolytic re- fining. The flue gas of the blast furnace, containing about 3.5 to 4.0% sulfur oxides, is mixed with the converter flue gas before it is delivered to the sul- furic acid ...
Recovery from copper-cobalt sulfide concentrates. The ores are treated by a sulfatizing roast in a fluidized bed furnace to convert copper and cobalt sulfides into soluble sulfates and iron into insoluble hematite.The calcine is subsequently leached with sulfuric acid from the spent copper recovery electrolyte.Oxide concentrates are introduced at this leaching step to maintain the acid balance ...
An average Ingerbelle copper process recovery of 88.5%, gold process recovery of 71%, and silver process recovery of 65% is based on geo-metallurgical domains, historical recoveries, and recent testwork. Average bulk density is 2.78 t/m3. Stockpile grades …

The second-phase expansion work at the Toromocho mine to expand the copper concentrate processing capacity was started in June 2018. The Toromocho expansion aims to increase copper production by 45%, increasing its capacity to 300,000 tonnes a year of fine copper in concentrates.
Jun 24, 2021· This year has seen Environmental, Social and Governance (ESG) issues rise to the top of the agenda for the base metals industry. Last year was one of the warmest years on record, with global temperature at 1.2 degrees above the pre-industrial baseline. Action must be taken soon to stop or mitigate further consequences of climate change. The focus on ESG is growing rapidly, the need for …
During 2006, Morenci mined 247Mt of ore, milled 4.1Mt grading 0.56% Cu, placed 230.70Mt of ore onto leach pads, recovered 14,993t copper in concentrate, and electrowon 355,574t of copper cathodes. Copper production in 2011 stood at 614 million pounds.
