Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.
25-07-2013· A wide variety of collectors has been proposed for oxide copper flotation without sulfidization in the past six decades. These include a large number of organic complexing agents, fatty acids, fatty amines, and petroleum sulfonates. Except for a very limited use of fatty acids (which are quite non-selective), none of the proposed reagents has been used in an operating plant, though a large number of collectors …
Copper Mining and Extraction: Oxide Ores Most of the copper ores mined today are oxide or sulfide ores first physically by froth flotation, Inquire Now Flotation Tests of Zinc Oxide Ore …
25-07-2013· On some ores the desired results were not obtained with hydroxamates for reasons unrelated to the chemistry of the collector. Oxide copper in the ore is perhaps not recoverable by flotation. Insufficient efforts have been made to demonstrate the efficacy and cost benefits of using alkyl hydroxamates in a plant.
25-07-2013· In this flotation tests and evaluation for the best collector for copper oxide "ore" 911Metallurgy continues with material that's 60% Oxide copper.. Sample C: 1.7% Copper about 60% Oxide Cu . Rougher Tests:. Both reagents appear to behave similarly as the "blue dots" are seemingly a continuation of the trend started by "red dots".
Copper Mining and Extraction: Oxide Ores. Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an ...
Home-otation copper oxide ores  12.3 Primary Copper Smelting. charge material of copper concentrate mixed with a siliceous flux (often a low-grade copper ore) is heated in air to about 650°C (1200°F), eliminating 20 to 50 percent of the sulfur as sulfur dioxide (SO2).
RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan M.S., Department of Mining Engineering Supervisor: Prof. Dr. Mustafa Ümit Atalay December 2014, 65 pages 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.
List of copper ores. Jump to navigation Jump to search. Following are the list of minerals that serve as copper ores in the copper mining process: Name Formula % Copper when pure Chalcopyrite: CuFeS 2: 34.5: Chalcocite: Cu 2 S: 79.8: Covellite: CuS: 66.5: Bornite: 2Cu 2 S·CuS·FeS: 63.3: Tetrahedrite:
25-09-2016· The oxide orebodies, in which the copper is present about half as sulfide and half as oxidized minerals, and where the recovery to be expected is 25 or 30 lb. per ton of ore, might well be treated first by the method used at New Cornelia, to recover the oxide copper, then reground and sent through the regular flotation operation.
