FLOTATION OF COPPER

FLOTATION OF COPPER-NICKEL SULFIDE ORES. United States Patent 3667690. Abstract: Flotation of sulphide minerals from their ores is achieved by a process in which two or more conditioning steps are carried out prior to a froth flotation step. The first step comprises conditioning a pulp of the ore in the presence of at least one alkaline agent

NICKEL AND COBALT ORES: FLOTATION

A typical example of a nickel sulRde plant operat-ing with highly Soatable talcose gangue is at Trojan mineinZimbabwe.TheZimbabweansulRdedeposits contain very low grades of nickel (0.6%) and copper (0.04}0.4%). The easily Soatable non-sulRde min-erals dilute the grade of the concentrate and also result in nickel losses into the tailings. This

Improving the Flotation Circuit Performance Using

Jan 01, 2018Jan 01, 2018Froth flotation is used to produce nickel and copper concentrates. As is the case at other operations, the presence of magnesium is detrimental to the flotation products. In the past year, the exploitation of a new deposit has increased magnesium in the feed. Thus, it has been challenging to meet the required ratio in the final nickel concentrate.

16. Flotation of Nickel and Nickel–Copper Ores

The reagent practice in the flotation of nickel and copper–nickel ores depends on three basic factors: mineralogy of the ore, flowsheet employed in the treatment of a specific ore, and degree of

Flotation of Nickel

All the flotation test-work was done using the Denver laboratory machine with a 1.5l stainless steel flotation cell. The required mass of nickel-copper sulphide ore material ground to 70% passing 75 m was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about

FLOTATION OF COPPER AND NICKEL SULFIDES FROM TALCOSE

A method for the flotation of nickel and copper sulphide minerals from talcose bearing ores using an alkaline circuit in which at least one of the alkaline reagents is soda ash or ammonium hydroxide and following conditioning of the pulp with a collecting agent of the xanthate family to activate the nickel and copper sulphide materials, the pulp is conditioned with a flocculating agent to

Separation of Copper

Nov 23, 2018Although copper and nickel are mutually soluble in the metallic state, in sulfide ores they occur as distinct minerals, usually chalcopyrite (CuFeS2) and pentlandite (FeNi)8S4). The separation of copper and nickel is achieved by differential flotation, if the mineral grains can be liberated by grinding.

Copper

Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails.
