Some copper sulfide ores can be partially oxidized, also influencing the selection of a reagent scheme, with the exception being a hypogene sulfide copper ore. 2 There are two common options practiced in the treatment of these ores. These are (1) sequential copper flotation from pyrite and other sulfides, the most common practice in the treatment of sulfides ores and (2) bulk or semibulk ...

bearing oxidised coppercobalt ores have been carried out on an ore sample from lhe Fungurume deposit. This ore contained % Co as heterogenite and % Cu as malpchite (74 % of Cu content), chrysocolla (24 %) and sulphide copper (2 % ). The gangue minerais were mainly siliceous. Flotation tests have been performed by applying two different methods: direct flotation with fatty acids and ...
In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains % copper, % cobalt and % sulfur. An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 4045 years in the idled plant. It was established that recovery of copper and cobalt ...
The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching. The ore with % copper grade used in this study was obtained from ÇorumDangaz region of Turkey. Native copper, cuprite (Cu 2 O), tenorite (CuO), and malachite (Cu 2 (OH) 2 /CO 3) were the main copper minerals in the test sample. Quartz, calcite ...

In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains % copper, % cobalt and % sulfur.
Preliminary testworks for the evaluation of froth flotation performances on a sample of oxidised copper ore from Kulumaziba River (DRC).
Flotation experimental research is carried out on a certain oxidised copper ores in Huidong, Sichuan province. The ores belongs to the typical oxidised ores. For the characteristics of the mine and the scene of the test requirements, five different flowsheets were test. Under the proper process conditions, the good technical indexes were obtained in all flowsheets.
Oxide copper ore flotation with 800 g/ton sodium oleate at pH 9 yielded % Cu with % recovery in a rougher circuit. To enhance the flotation performance, in terms of %Cu, optimum dosages of sodium silie, quebracho, and pine oil were examined. At the optimum dosages, the grade increased to % Cu with % recovery. To upgrade the rougher concentrate, sodium oleate was added in the ...
