how much copper ore is got out of the ground

Copper extraction Wikipedia

The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals. The ore is then wetted, suspended in a slurry, and mixed with xanthates or other reagents, which render the

Copper processing Ores Britannica

Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.

Peak copper Wikipedia

Reserves. Copper is a fairly common element, with an estimated concentration of 50–70 ppm (0.005–0.007 percent) in earth's crust (1 kg of copper per 15–20 tons of crustal rock). A concentration of 60 ppm would multiply out to 1.66 quadrillion tonnes over the 2.77e22 kg mass of the crust, or over 90 million years' worth at the 2013 production rate of 18.3 MT per year.

Extracting copper. How much is left?

known deposits are being worked and new methods of copper extraction are being developed e.g. using bacteria to 'eat' the copper out of low grade ore; some deposits do not contain enough copper to make them economic to extract there are many copper deposits that have not yet been found deposits are still being built up on the seabed.

Copper Refining: From Ore to Market INN

The copper is concentrated further by slurrying the ground ore with water and chemical reagents. In this process, air is blown through the mixture, and the copper floats to the top. The copper is

Mining Underground mining Britannica

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the

Everything You Need to Know About Copper Porphyries

Mar 11, 2015· Large Size, Low Grade Porphyries typically have 100 million to 5 billion tonnes of ore with a lower grade (0.2% to >1% copper). It is the size of these deposits that allow for bulk mining and economies of scale.

Green Energy Reality Check: It's Not as Clean as You Think

Jul 09, 2020· While ore grades vary widely, copper ores typically contain only about a half-percent, by weight, of the element itself: thus, roughly 200 tons of ore are dug up, moved, crushed, and processed to get to one ton of copper. For rare earths, some 20 to 160 tons of ore are mined per ton of element. For cobalt, roughly 1,500 tons of ore are mined to

Extracting copper. Extracting copper.

The copper ore has to be dug from the ground. The ore contains some copper mineral and lot of waste rock. The copper mine in picture 4 produces 6 tonnes of copper from every 1000 tonnes of ore. Extraction: An ore has to be changed chemically into the metal. This process is called reduction.

Prospecting from Orbit NASA

Mining for ore isn’t what it used to be. A hundred years ago when a mining operation happened upon a copper vein or a gold deposit, the outfit would often just rip out the local flora, excavate the land, and dump the resulting waste and rubble in the nearest pristine stream or flowering meadow.

How Is Iron Extracted From the Earth? Reference

Mar 26, 2020· Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

The gravel-like material then enters rotating drums filled with steel balls. In these drums, the ore is ground to a fine slurry or powder. Next, mill operators thicken the slurry with water to form pulp and run the pulp through a series of leaching tanks. Leaching dissolves the gold out of the ore using a
