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 important by-product of this process is used for the extraction of oxide ores.

Copper Oxide Flotation - Mineral Processing & Metallurgy

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 …

Copper Oxide Flotation - Mineral Processing & Metallurgy

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.

Oxide Flotation Collector | Collector for Copper Oxide Ore

Treatment of Mixed Sulfide Oxide Ores of Copper

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.
