Copper Nickel Flotation

The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed 0.35 pct …

How to Separate Copper from Lead by Cu Depression

Copper recovery to this concentrate was only 3%. For the same three tests, copper was 57% recovered from the feed into a concentrate grading 27% Cu. The average lead grade was 5%. Copper recovery was low in the batch test as there was significant copper remaining in the bulk Flotation cleaner tailings.

Feasibility Study of Differential Flotation of Cu–Pb–Zn …

In this research, flotation of copper, lead and zinc minerals from a copper oxide–sulfide ore was studied. The identification tests showed that the sample is a mixture of quartz, chalcopyrite, galena, cerussite, hemimorphite and iron oxide minerals with 5.04% CuO, 1.61% PbO, 2.07% ZnO and 56.40% SiO2. The experimental design methodology …

Effect of Copper Sulfate on Zinc Sphalerite Flotation

As an example of the beneficial effect of copper sulfate in the activation of zinc sphalerite toward flotation, the series of results shown in Fig. 1 is of interest.These represent rougher tests on a sample of heavy pyritic ore. The particular sample in question contained about 5.6% zinc as marmatite; and was treated in a circuit made alkaline with …

Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation

The Problem with separating Copper from Zinc by flotation The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present. This is usually the case in ore deposits near the surface or in tropical countries where the annual rainfall is quite high. …

Effect of pre-oxidation on copper-lead bulk concentrate flotation …

Based on the flotation principle of "suppressing more and floating less", cyanide is commonly used to suppress copper minerals in Cu-Pb bulk concentrate with a Cu/Pb mass ratio greater than 1, which has been proved to be effective in dressing plant [7].

Separation of Copper-Nickel by Flotation and Magnetic Methods

This report describes the results obtained from separating mattes smelted from Duluth Gabbro bulk flotation concentrates into copper-rich and nickel-rich fractions by mineral dressing techniques. In conventional processing of mixed sulfide ores of copper and nickel, the separation of copper from nickel begins in the ore beneficiation plant.

Selective Flotation

Who would think that Selective Flotation of copper, gold, zinc or any metal would required that one must be able to feel pain and recognized and/or admit when it hurts. Flotation mass-pull is a process that is often misunderstood; a learner's mistake made by non-operating types.. You do not need to pump anything in the lab.. In …

A Review of the Flotation of Copper Minerals

The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance....

Froth Flotation Handbook

Conditions of operation of froth-flotation. Froth-flotation is in general effective only on ores ground to pass 0.3-mm. aperture or less and the agitation-froth and bubble-column processes are most effectively practiced when the bulk of the feed will pass a 0.074-mm. screen.

Gold Flotation

Flotation reagents of the Naval Stores Division of the Hercules Powder Company are as follows: Yarmor F pine oil, a frother for floating simple and complex ores; Risor pine oil, for recovering sulphides by bulk flotation; Tarol a toughener of froth, generally used in small amount with Yarmor F, but with some semioxidized ores where …
