Copper Sulfide Flotation Mineral Processing & Metallurgy

Copper Sulfide Flotation Circuit. The pulp from the Conditioner is treated in a 10-cell “Sub-A” Flotation Machine and a 4-cell “Sub-A” Flotation machine. Sometimes conditioners are not provided; however, their use insures that reagents are thoroughly mixed into the pulp ahead of flotation. This gives a more uniform feed and effective use of reagents plus improved flotation conditions

This bulk concentrate is sometimes separated into individual copper and nickel concentrates by froth flotation of chalcopyrite from pentlandite at a pH of about 12. Lime, CaO, is used to adjust the pH of the

A comparison of the flotation of ore from the Merensky

Wet grinding can favour the stone surface reaction products. Dry fine grinding can result in the oxidation of sulfides. As can be expected, changes in structure and enthalpy of solids during grinding in air and in aqueous environments are different, and as a result, subsequent flotation of the ore greatly depends on the grinding environment

Role of Sodium Sulfide Copper Lead & Zinc Ore Flotation

Sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper, lead, and zinc minerals in their oxidized form. The sulfidization process, developed in the U.S.A. in 1915-20 for oxide copper minerals flotation, is especially suitable for oxidized lead ores in which the gangue is usually basic. The early users of sulfidization had realized that the reaction of

Effect of using different grinding media on the flotation

In the present investigation flotation was used as a diagnostic to understand the effects of changes to the media during the grinding stage. A Base Metal Sulphide (BMS) ore was ground under media of different shapes and compositions to determine the effect of different rod/ball material on the flotation performance of the ore.

Copper Ore Processing Methods

Ores containing coarse sulfides of copper and oxidized ores containing cuprite, which respond to both gravity and flotation methods; these may be concentrated by gravity methods to recover the coarser particles and the tailing from the gravity machines by flotation; or fine-grinding and flotation only may be used. In most modern plants the gravity step is omitted.

Mechanochemical sulfidization of a mixed oxide-sulphide

Mechanochemical sulfidization of a mixed sulfide/oxide copper ore by co-grinding with sulfur and additives including Mg(NO 3) 2 and Fe(NO 3) 3 salts and iron, aluminum and magnesium powders was investigated for the first time. Also, the influence of sulfidization during the wet-milling process was examined on the separation efficiency and recovery of copper in detail.
