CHAPTER 7 FLOTATION OF SULPHIDE MINERALS

Flotation of Chalcopyrite (CuFeS 2) Complete flotation of chalcopyrite is possible from pH 3 to pH 12 with ethyl xanthate. Both electrochemical oxidation of xanthate to dixanthogen as well as chemisorption of xanthate on chalcopyrite are responsible for flotation when xanthate is added as collector. Depression of chalcopyrite 1. Hydroxyl as

Effects of grinding media on grinding products and

However, the flotation recovery of chalcopyrite is about 16% higher in the case of grinding with CB medium than with CIB medium for the same sodium butyl xanthate dosage. Fig. 9b shows the effect of pulp pH on chalcopyrite flotation using different grinding media systems. As the pulp pH increased from 2 to 10, the chalcopyrite recovery in the

Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two decades of this century, whenopen pit mining, flo tation concentration,and the reverberatory

Chalcopyrite and pyrite floatabilities in the presence of

ABSTRACTOne of the principal problems in flotation of copper complex ores is the presence of pyrite and copperactivated pyrite in moderately alkaline pHs. Misreported pyrite into copper concentrates dramatically declines copper grade and its recovery. In this study, the effect of sodium sulfide, sodium metabisulfite (SMBS), and their dosages (100, 200, 300, and 400 g/t) were investigated on

How is chalcopyrite mined Answers

Chalcopyrite is famously minded at Olympic Dam, one of the largest mines in the world. What is the most common ore of copper? The most often mined ore of copper is the mineral chalcopyrite.

How to carry on the flotation of Chalcopyrite Knowledge

Chalcopyrite exhibits natural floatability under oxidizing conditions. In the flotation process, the iron ball milling opportunity is used to produce a strong reduction environment, thus affecting the flotation performance. Then, the flotation performance can be restored by

Activating flotation of chalcopyrite using CuSO4 and H2O2

surface properties. The flotation results indied that cyanide chalcopyrite was strongly inhibited by sodium cyanide, with the maximum flotation recovery of 22.5% only. CuSO 4 and H 2 O 2 significantly improved the flotation of cyanide chalcopyrite, and the flotation recovery was increased to 92.28% and 84.35%, respectively.

Chalcopyrite: Mineral information, data and localities.

Chalcopyrite Group. ChalcopyriteEskebornite Series. A major ore of copper. Common in sulfide veins and disseminated in igneous rocks. Weathering may lead to the formation of malachite, azurite, brochantite, langite and numerous other secondary copper minerals. A Znrich variety is known from Atlantis II Deep (see zincian chalcopyrite).Also, the MidAtlanticridge isocubanite may transform to

Recover Ultrafine Chalcopyrite by Flotation

In the flotation of chalcopyrite, there was no conclusive evidence that some of the ultrafine chalcopyrite particles are selectively flocculated with each other during conditioning or flotation. KAX added to a slurry of pure chalcopyrite showed extensive flocculation. But those experiments were conducted without gangue minerals.
