Sulﬁde Mineral Flotation Maurice C. Fuerstenau Subhash Chander and Ronald Woods INTRODUCTION Froth flotation was developed at the Broken Hill mine Australia a century ago with the flo- tation of the common sulfide mineral sphalerite. With this development billions of tons of worthless rock containing a variety of valuable metals became ore.
Synopsis. This paper presents both the fundamentals of sulphide mineral flotation and the practical aspects of sulphide ore flotation. The fundamental aspects of the flotation of sulphide minerals both in the absence and presence of thiol collectors are discussed in relation to their crystal structure surface chemistry and electrochemical characteristics.
"Today& 39;s major challenges facing the flotation of sulfide minerals involve constant variability in the ore composition; environmental concerns; water scarcity and inefficient plant performance. The present work addresses these challenges faced by the flotation process of complex sulfide ore of Mississippi Valley type with an insight into the froth stability and the flotation performance. The ...
The froth flotation and concentration method used exclusively for sulphide ores varies according to the mineral composition and ore floatability. The mainly used design flow is compressed air-pine oil and flotation reagent-foam containing sulfide ore and outlet for gangue.
In sulphide minerals flotation these reactions involve oxidation of some species and reduction of others resulting in selective adsorption of collector on the mineral surfaces Chander 1988 . The collectors used in sulphide flotation are anionic collectors xanthates dithiophosphates thionocarbamates etc. characterized by the presence ...

Flowsheet for treatment of Copper Sulfide ores rich in minerals such as chalcopyrite with gold and silver as well as arsenopyrite. The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore ranging from 60-65% silica with pyrite arsenopyrite and calcite with 3 to 4% copper ...
In sulfide flotation recovery and selectivity are fundamentally dependent on the relative rate constants of various mineral phases Boulton et al. 2003 . Therefore an evaluation of the hydrophobicity balance by mineral particles requires accurate selection of the mineral phase.
