copper concentrate moisture temperature
Estimated Water Requirements for the Conventional …
Resultsingle copper concentrate has been modeled for this study. In 2011, approximately 13 million metric tons (Mt), or about 80 percent of the world's primary copper supply, originated from concentrate produced by flotation (International Copper Study Group, 2012). In 2011, about 60 percent of primary

Copper Concentrate Enrichment Process
ResultMost copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps.
