How Do you separate copper ore from rocks?

Copper ores, will be heavier than most of the background rocks, and will generally be brightly coloured green or blue. Gravity separation usually suffices to separate the ore. The metal is separated from the ore by heating in a reducing atmosphere to remove sulphides, etc.

Powdering the rock The next step was to take the crushed pieces of rock and make them even smaller. We used a heavy metal rod (a broken half shaft from a four wheel drive) and smashed the small bits of rock in a saucepan. The rock needed to be powdered for us to get to all the gold within the rock.

Sediment-hosted copper deposits are stratabound, that is, they are restricted to a narrow range of layers within a sedimentary sequence but do not necessarily follow sedimentary bedding. They are epigenetic and diagenetic, that is, they are formed after the host sediment is deposited, but in most cases, prior to lithification of the host.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.

Extracting metals from rocks- Learn Chemistry

Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO 3.Cu(OH) 2. This experiment involves producing copper from copper(II) carbonate. The copper carbonate is first heated to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.

Mines ~ Mining Geology

Tiny grains of ore minerals, mostly copper and iron sulfides, are scattered within what is called "host rock." Because there is far more host rock than there are minerals, it is known as a low-grade ore deposit. Because this is a low-grade deposit, a ton of ore contains only about 10.6 pounds of copper.
