Principles and pract of sulphide mineral flotation

Synopsis. This 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.

A technique to determine ore variability in a sulphide ore

EDTA results of 90 drill core samples showed that there was a large variation in EDTA values, which could be due to variations in ore mineralogy and surface oxidation. Presence of secondary copper minerals and high degree of surface oxidation are known to adversely affect flotation performance of sulphide ores . In spite of that there are still

Copper extraction - Wikipedia

Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant. Sulfide smelting

Flotation Reagents - Mineral Processing Metallurgy

Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.
