Flotation of Silver Bearing Minerals from Sulfide Ores

2018-3-19  About two-thirds of the world’s silver resources are contained in base-metal sulfide deposits (Reese, 1991). These ores are beneficiated almost exclusively by flotation. Silver recovery during flotation, however, often is low, especially in the complex, fine-grained ores

2021-1-1  In the mineral processing industry, lead-zinc sulfide ores are usually processed by froth flotation to enrich the purpose minerals [1]. Flotation is a complex process, and the selective separation of minerals depends on the balance between the hydrophilic species and hydrophobic species on the mineral surface [2], [3].

1 Froth Flotation – Fundamental Principles

2009-8-27  The collectors available for flotation of oxide minerals are not as selective as the collectors used for sulfide mineral flotation, as they attach to the surface by electrostatic attraction rather than by chemically bonding to the surface. As a result, there is some collector adsorption onto the minerals that are not intended to float.

FLOTATION OF COPPER SULFIDE ORES - STEPHAN

The ore is a sulfide copper ore containing heads of approximately: copper 0.45, iron 3.5, molybdenum 0.006, and zinc 0.06 per ore sample. Prior flotation of this ore has employed, in the flotation cell, the addition of pine oil as required to optimize froth, ordinarily resulting in a total pine oil concentration of about 0.24 lb./ton.

EXTRACTING METALS FROM SULFIDE ORES

Many approaches were pursued to solve the "sulfide problem" at Broken Hill before selective flotation was developed. The successful involves first crushing the ore, typically to a particle size of about 5 to 50 micrometers, to liberate separate grains of the various valuable minerals and worthless gangue components.Then the particles are pulped with water, and the surface of the ...

The Critical Role of Pulp Density on Flotation

Figure 2c presents the apparent viscosity values as a function of the sulfide ore and serpentine density. In this study, an apparent viscosity of 100 s −1 was chosen because this was the average shear rate value in a flotation cell . As can been seen, pulp density had little impact on the sulfide ore
