Direct from the pit the oxide ore is piled onto large lined leach pads and the sulfuric acid. The top photo shows one of these leach pads with the new thick black plastic liner visible on the right of the pad. The copper oxide minimum minerals are dissolved by the acid to give a blue copper rich solution mainly of copper sulfate.
Metallurgical data are shown in these flowsheets which incorporate Crushers, Grinding Mills, Flotation Machines, Unit Flotation Cells, and Selective Mineral Jigs as well as other standard milling equipment.

Brought on stream in 1975, the 10,000-tpd copper oxide processing plant of Anamax Mining Co. at Twin Buttes, Ariz., is now at design capacity. Based on acid agitation leaching, solvent ion exchange, and electrowinning, the Anamax plant bridges an ore to metal gap by producing mine site copper cathodes from lime-bearing oxidized feed. Until recently, such material was …
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 [48].

The processing of gold copper and copper gold ores can be highly problematic, site specific and the process selection is dependent on ore grade, mineralogy, acid leach behaviour, cyanide …
Thus a copper ore consisting of chalcocite in a gangue of rock-forming silicates will yield, under a given method of treatment, a higher grade of concentrate and show a higher ratio of concentration than another copper ore of identical copper content, in which the copper mineral is chalcocite, but in which pyrite is associated with the other ...

Abstract The ore from Baiyinchagan mine is typical increasingly refractory as the mine get deeper, especially the increasing lead and zinc contents, which not only detrimentally affects the product quality of copper concentrate, but also results in the loss of lead and zinc resources In order to solve the problem, two routes were conducted: first, depress liberated …
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.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, …
Four fundamental concepts underlie the construction of an ore dressing plant simulator. * Ore dressing plants are collections of unit operations connected by process flow streams that transmit material from one unit to the next. The flow of materials is directed by the flowsheet structure.
Grinding Porphyry Copper Ore. The flowsheet illustrates a typical grinding circuit with a rod mill in open circuit. Its discharge, usually all —14 mesh, goes to a classifier for removal of finished material. ... This arrangement for upgrading concentrates is universal in its acceptance by the ore dressing industry. Two or more stages of ...
Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment ... has been a noticeable feature of many new plants in Canada. This flowsheet permits a coarser grind of the main bulk of the tonnage with an attendant increased recovery and reduction in ...
It was felt by some that crushing to this fine size is only possible if the ore is friable and is relatively soft in comparison to the harder ores. Our results show that some of the copper ores are as hard as taconite and are crushed to ball mill feed all passing 13MM (½").
The plant receives three different types of copper-cobalt ores, mainly from three mines: Shangolowe, grading about 2.90% Cu and 0.12% Co (Kime, Ntambwe, and Mwamba, 2015); Kamfundwa, grading an ...
