Leaching Coarse Native Copper Ore With Dilute Ammonium

Experiments on ammonium carbonate leachng of native copper ores crushed to 1inch size showed that in 30 days 55 percent of the copper was extracted from 0.7 percent copper conglomeratetype ore, and 85 percent was extracted from 2.1 percent copper amygdaloidtype ore. Cupric ions were not

Oxide copper ore, lowgrade copper sulfide overburden, and other coppercontaining materials are stacked into a heap. Leach solution (pH approximately 2) is sprinkled or flooded on top of the heap and percolates through. The leach solution containing the dissolved metal eventually flows out of the heap into a collection pond.

Innovations: Introduction to Copper: Mining & Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfurbearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Within the state of Michigan, copper is found almost exclusively in the western portion of the Upper Peninsula, in an area known as the Copper Country.The Copper Country is highly unusual among coppermining districts, because copper is predominantly found in the form of pure copper metal (native copper) rather than the copper oxides or copper sulfides that form the copper ore at almost
