Aug 21 2020 The first step in this process is crushing and powderizing ore in a ball or rod mill. Virtually all sulfide-type copper ores including chalcocite Cu 2 S chalcopyrite CuFeS 2 and covellite CuS are treated by smelting.
Copper mining is usually performed using open-pit mining in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore boring machinery is used to drill holes into the hard rock and explosives are inserted into the drill holes to blast and break the rock.

Copper ore in concentrations ranging from 0.29 percent to ten times that amount is mined from open pit or underground mines. The crushed mine ore is ground in rod and ball mills and then sent to flotation machines where the copper mineral rises to the top in a froth making a copper concentrate of approximately 30 percent 27 percent iron and 33 percent sulfur.
Dor Copper Mining Corp.'s DCMC:TSX.V; DRCMF:OTCQB assets contain some of the highest-grade undeveloped copper-gold deposits in North America. The company's projects are located just 14 kilometers km from the town of Chibougamau in mine-friendly Quebec and are one of Canada's premier near-term redevelopment opportunities.

KAZ Minerals previously known as Kazakhmys owns the Aktogay open-pit copper mine. It is the largest copper producer in Kazakhstan located in the eastern region of Kazakhstan approximately 250km from the border with China. The project comprises of an open-pit mine and an on-site concentrator to produce copper cathode from oxide ore and ...
Mining at Aitik started on the basis of a 50t reserve but by 1998 the mine had yielded 300t of ore. As of November 2009 ore reserves were 747t grading at 0.25 of copper 0.14g per tonne of gold 1.7g per tonne silver and 29g per tonne molybdenum. Proven and probable ore reserves amount to 518t and 229t respectively.
Mining has occurred through pretty much all of the history of New Mexico. The Chino Mine is the third oldest still active open-pit copper mine in the entire world. It was founded in 1910 but there is evidence of mining in the area from long before that. For example in Madrid NM there is evidence of historic mining from the 1850s.
Nov 08 2020 Known for its free-milling high-grade gold-bearing ore the mine’s early production from 1900 to 1931 included 125000 worth of which 75000 was gold and the remainder silver.

The 24’ x 39.5’ Ball Mill The Copper Mountain ball mills are 7315 mm 24 feet in diameter and 12040 mm 39.5 feet long. They are overflow discharge ball mills with inside diameters of 7315 mm 24 feet and grinding lengths of 11887 mm 39 feet. Each Ball mill is
The mixture of ore and water is further broken up in two ball mills which are like a rod mill except steel balls are used instead of rods. The slurry of finely ground ore that emerges from the final ball mill contains particles about 0.01 in 0.25 mm in diameter.
The ore from the mine contains about 2 copper. To get at the copper the first stage is crushing in huge cylindrical ball mills. Ball mills crush the ore into a fine powder. Courtesy of Rio Tinto. Stage 2: Froth flotation The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent.
