Secondary Copper Ore Recovery

covers the supply of primary copper. Table 2 presents data on the supply of copper from secondary sources. In Table 3, statistics on the consumption of primary and secondary metals by mills, foundries and other industries are summarized. These three tables are provided by GMC. Finally, Table 4

Sulfide ores. Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.. Supergene ores rich in sulfides may be concentrated using ...

Current copper deposits contain significant amounts of secondary nonsulphide minerals and newly discovered deposits are increasingly complex. As a result, research into the improvement of sulphideoxide copper ores processing through the use of mixed collector systems has surged.

The highest copper recovery was equivalent to %, obtained after 21 days at 35 degrees using the Acidi Thiobacillus Ferrooxidans bacteria and a K9 medium with a pulp density of 10% and pH Keywords: Optimization, Copper, Bioleaching, Bacteria, Acidi Thiobacillus Ferrooxidans. 1. Introduction World reserves of highgrade ores are declining

Copper Cobalt Africa, ... The recovery of other valuable metals such as gold and silver can be carried out economically. ... Ferric sulphate leaching of secondary sulphide ores has been successfully commercialised at the Cobre Las Cruces (CLC) and Sepon copper plants.

ca. 6% copper, Nussir is one of the largest deposits in Norway. Nussir copper ore is comprised within a relatively simple deposit with very highgrade copper minerals, and the presence of other iron sulphide impurities are negligible in the ore. The latest mineral resource estimation is from July 2014,

During 2006, Morenci mined 247Mt of ore, milled grading % Cu, placed of ore onto leach pads, recovered 14,993t copper in concentrate, and electrowon 355,574t of copper hodes. Copper production in 2011 stood at 614 million pounds.

At a blend of 70% sulphide ore and 30% oxide ore, the rougher scavenger copper recovery was as high as %. The copper recovery from the blended ore using a mixture of collectors was shown to be ...
