2011-12-1 Today, about 400 million tons of sulphide ore is treated annually by flotation process worldwide. General principles and factors effecting flotation process, control systems, innovations and new trends are reviewed in the paper. M/s Hindustan Zinc Ltd, a leading mining and smelting company in India treats annually 3.5 million tons sulphide ore.

This technology has acclaimed importance as a versatile process for the beneficiation of vast variety of sulphide mine-rals. Due to flexibility of the process and remarkable development taken place in flotation technology and its ancillary systems, it has now become possible to recover fine grained sulphide minerals from compiled ore deposits, whose processing was earlier considered un-economical.

2020-7-15 The flotation of sulphide-vapour aggregates is likely to occur in crustal magma reservoirs and provides a feasible mechanism for the removal of sulphide liquid from crystal mushes, promoting its ability to participate in the generation of magmatic sulphide and porphyry copper deposits, emissions of the metals during volcanic eruptions, and even the remobilization of chalcophile metals sequestered in

1988-8-1 1988-8-1 Under favorable conditions of flotation there is competition between reactions leading to formation of hydrophobic species with reactions that lead to formation of hydrophilic species. Due to the sluggish nature of the reactions involving sulfide minerals, a knowledge of the kinetic behavior of the system is necessary.

2009-8-26 flotation of the sulphide mineral surface had been achieved at lower dosages than was required with di-C2-DTC and C2-X. The superior rate of flotation of the copper minerals with di-C2-DTP may be attributed to the added hydrophobicity provided by the additional alkyl group of di-C2-DTP compared to C2-X. However, the poor performance of di-C2-

2019-7-9 The floatability of common copper sulfide minerals is reduced in the following order: chalcopyrite > covellite > bornite > chalcopyrite. (4) The floatability of copper sulfide minerals is also affected by factors such as crystal grain size, grain size, etc. fine grain is not easy to float.

2020-4-8 2020-4-8 Gould: The key trends are toward higher mineral selectivity and greener chemistries. Currently flotation reagents are dominated by chemistries that are decades old, and in some cases more than a century old. These reagents were developed in a time when mineral head grades were much higher and environmental impacts were less of a concern.

PDF FROTH FLOTATION : RECENT TRENDS Flotation of Sulphide History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique.

1988-8-1 The use of various electrochemical techniques to study mechanisms of sulfide mineral-flotation reagent interactions is briefly reviewed in this paper. Prior to such studies it is desirable to thermodynamically determine solution conditions favorable for formation of hydrophobic species deemed to be responsible for flotation. The thermodynamic equilibrium involving both the stable and ...

As part of a study investigating the influence of mineralogical variability in a sediment hosted copper–cobalt deposit in the Democratic Republic of Congo on flotation performance, the flotation of nine sulphide ore samples was investigated through laboratory batch kinetics tests and quantitative mineral analyses. Using a range of ore samples from the same deposit the influence of mineralogy ...

The use of R and K parameters, based on laboratory data, is also important, as significant trends in R and K have been identified for controlled changes in each factor setting of the flotation system. Thus, for example, increasing the dosage of any collector consistently causes an increase in R for a given flotation feed but eventually lowers the K at higher dosage (thus, the flotation curve ...

2019-7-9 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.
