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 copper-mining 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 …
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 sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

About that, yeah. I've got a 30 pound chunk of float copper from this very locality, the upper peninsula of Michigan, right here in my room. Native copper is deceptively dense, dense stuff. I still don't have a freaking clue how this kind of native copper mineralized in Michigan, though.
Float Copper is also called Drift Copper or Butchite.The term Butchite appears to be a local term that is given to a piece of Float Copper that has been polished and sealed to prevent further corrosion. Most of the Float copper is found in Michigan.

Float Copper. $26.00: M253hc A nice specimen of natural Copper from Keweenaw Peninsula, Michigan. This is natural native copper which has been mostly removed from the matrix rock which was surrounding it. There is matrix rock visible in many areas of the specimen.
I think that thet the dull gray to black patina on native copper and native silver might actually be copper and silver sulfides. Copper and silver are sulfur getters. They draw sulfur out of the air. I wonder is a quick flash in diulte nitric acid might produce a tolerable and not overly bright finish.

Oxide copper ore, low-grade copper sulfide overburden, and other copper-containing 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.
This is related as: 1) iron sulphide mineral levels are usually much higher than copper concentration, 2) sulphide flotation collectors can float iron sulphides well also, 3) liberation can be an issue making copper and iron separation difficult, and 4) fine particles are often more difficult to separate.
Froth Flotation (Sulphide & Oxide) ... behind Nchanga concentrator in Zambia), and stage added dodecyl mercaptan as collector for the native copper. The native copper would tend to float in the scavenger circuit, but would tend to concentrate itself in the regrind circuit, and often fell out in the re-cleaner circuit (if it made it that far ...
This page lists native copper which is found in many forms and from various formations. Copper can be found in matrix, nuggets, sheet, vein, float, smelted, Types of formations include igneous, sedimentary, including conglomerate.
Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings.
Experiments on ammonium carbonate leachng of native copper ores crushed to 1-inch size showed that in 30 days 55 percent of the copper was extracted from 0.7 percent copper conglomerate-type ore, and 85 percent was extracted from 2.1 percent copper amygdaloid-type ore. Cupric ions were not …
Copper Upgrade (%) 169% • Heavy medium separation is the process of separating copper ores by a specific medium (ferro-silicon) density. • Testwork on copper ores at a size range of -76 mm+ 6 mm and a medium density of 2.8 demonstrated that 49% of the mass can be rejected whilst only losing 14% of copper – an upgrade of 169% .
