copper oxide ore concentrator
steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.
Recovery from copper-cobalt oxide concentrates. The ore is comminuted and the cobalt rich oxides are separated by froth flotation. The cobalt-bearing concentrate is then mixed with lime and coal, and then melted in a reducing atmosphere. Iron and lighter impurities float to the surface as solid dross or are expelled from the melt as gas.
heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated . Pyrometallurgical copper production Figure 3: Typical flow sheet for pyrometallurgical copper production from ore concentrates
The modeling of the leaching of copper oxide ores has not received as much attention as sulfide heap leaching. The acid leaching of copper oxide ores generates a vertical acid concentration gradient in the ore heap, which is not generally observed in sulfide deposits.
After this stage the enriched ore now contains about 25% copper by mass and is called copper concentrate. It is valuable enough to ship to other plants and other countries for processing. For example China, Germany and Japan are major copper producers that use concentrate from around the world.

How copper is made - material, used, processing, steps, product . The first mention of the systematic extraction of copper ore comes from …
Heavy minerals such as ilmenite or hematite settle out rapidly in a spiral concentrator and they should be removed as soon as a good wide band forms. Since the concentrate band is wider at the top, splitters near the top of the spiral concentrator should be opened wider than those near the bottom.
Sulfide ores are moved to a concentrating stage, while oxide ores are routed to leaching tanks. The first commercial copper product, in an increasing chain of added value, is the copper concentrate, which main components are copper, iron and sulfide.
Copper Ore Types: Sulfides vs. Oxides. ... copper oxide ores and copper sulfide ores. ... Different methods are used to process copper sulfide ores depending on the concentration of copper within ...
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

About 80% of the world's copper-from-ore originates in Cu-Fe-S ores, such as chalcopyrite (CuFeS2) and chalcocite (Cu2S). The concentration of these minerals in an ore body is low. Typical copper ores contain from 0.5% Cu (open pit mines) to 1 or 2% Cu (underground mines).
Copper ore concentrator. Copper ore concentrator is used to remove unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. Copper ore concentrate process. Copper ore concentrate process is used for ore beneficiation through crushing and grinding plant.
