Nov 04 2013The Cerro Verde copper mining complex includes a concentrator facility with ore milling capacity of 120 000tpd and a solvent extraction and electro-winning (SXEW) facility A large-scale expansion plan is underway to raise the concentrator capacity up to 360 000tpd by 2016 Cerro Verde has been operational since 1976
A Copper Flotation Flowsheet Because the copper in this type of ore usually assays only plus or minus 1% copper the porphyry copper operations must be relatively large in order to be commercial The flowsheet in this study illustrates a typical 3 000 ton per day operation
At present although considerable leaching and direct-smelting ores are produced the bulk of the copper ore mined is concentrated The milling of copper ores as practiced in the larger concentrators has changed to such an extent that comparatively few of the machines in use at the beginning of the period remain in service today
We produce lead copper and zinc concentrates to sell around the globe Production in this area began in 1960 Since that time we have mined more than 300 million tons of ore from the Viburnum Trend Doe Run and our Missouri mining predecessors have mined more than 500 million tons of ore

Copper ore was discovered about 1712 in what is now North Arlington and the Schuyler Copper Mine extracted ore and shipped it in casks to the Netherlands The success of the Schuyler mine led to more prospecting and discovery of more deposits

Ores that contain copper in the U S are typically mined in large open-pits Copper processing facilities are usually located near mining or extraction sites Significant waste volumes are associated with copper production Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM

Sodium cyanide - A chemical used in the milling of gold ores to dissolve gold and silver Solvent extraction-electrowinning (SX-EW) - A metallurgical technique so far applied only to copper ores in which metal is dissolved from the rock by organic solvents and recovered from solution by electrolysis
Copper - From Beginning to End Copper is a major metal and an essential element used by man It is found in ore deposits around the world It is also the oldest metal known to man and was first discovered and used about 10 000 years ago And as alloyed in bronze (copper-tin alloy) about 3000 BC was the first engineering material known to man

The average grade of copper ores in the 21st century is below 0 6% copper with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock A key objective in the metallurgical treatment of any ore is the separation of

Only then are the copper minerals broken free of the rest of the rock to be separated by flotation Concentrating The slurry of water and pulverized ore is mixed with milk of lime to raise the pH and small amounts of special reagents: a frother to make bubbles and a collector chemical that causes the copper minerals to stick to those bubbles
