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 …

Pyrite and marcasite are widely found in most sulfide deposits and constitute an important component of sulfide gangues [31].Due to having identical chemical compositions and similar properties, they are often treated as the same mineral, which causes many problems for flotation.

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …

A state of the art review of pulp potentials in sulfide mineral flotation was presented. The measurement and interpretation of pulp potentials in sulfide mineral flotation dates back more than 30 years, yet the transfer of knowledge of pulp potential to industrial practice has been exceedingly slow.

Separating oxidized zinc minerals from flotation tailings is always a challenge. In this study, a flotation tailing from Wulagen zinc mine in China (Zn grade < 1%) was processed using froth flotation with combinations of amines (OPA 10, OPA 1214, OPA 13, DDA) and Na2S to study the effects of these amines on the zinc recovery as …

In the majority of the zinc operations, sphalerite (ZnS) is associated with galena and often sulfides of iron and copper. It is therefore essential to arrange the flowsheet not only for recovery of the valuable minerals, but also to selectively separate them into products acceptable to the smelters for ultimate conversion into metal. The …

Flotation of sulfide ores is the comprehensive result of a series of REDOX reactions, including oxidation of sulfide ores and collectors, and oxygen reduction. The results of this series of REDOX reactions are closely related to the interface potential of sulfide ore/pulp, and different interface potential leads to different surface products. ...

The mineral-collector interactions and the selectivity in separating individual sulfide minerals from each other and from the rest of the nonsulfide particles can be controlled by a careful adjustment of pH and oxidizing, reducing, and complexing additives. Figure 18 shows typical effect of pH and collector concentration on sulfide flotation ...

The extraction of nickel (Ni) from sulfide resources commences with flotation to produce a concentrate which is then smelted to produce a nickel-enriched phase called matte, and further refined to produce pure Ni products as well as by-products, such as cobalt (Co), copper (Cu) and precious metals. However,

This study highlights the necessity of revisiting into the electrochemical and/or galvanic interactions between the grinding medium and sulphide minerals, and interaction mechanisms between pyrite and other sulphide minerals in terms of their flotation behaviour in the context of inevitable H2O2 existence in the pulp liquid.

Finally, conceptual flowsheets are proposed for the extraction of metals from the tailings based on the results of the present study. It is expected that the present study could provide a technically feasible hydrometallurgical process to recover Ni and Co from sulfide tailings (e.g. flotation cleaner tails).

Keywords: flotation, process optimization, Taguchi orthogonal array, ANOVA. 1. Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores. One of the major challenges faced by the flotation of these ores is the ever varying grade and mineralogy as the ore is exploited (Kabuda et. al., 2011).
