Flotationis both a science and an art. It brings together many complex variables. Such basic factors as knowledge of mineral structure, chemical reagents, pH of mill water, pulp density,temperature, technical skills of the operator, the dependability of theflotationmachine, as well as a host of other factors which affect theflotationof each specific ore must be combined to produce ...

Metallurgical ContentLearn CyanidationDevelopments in the Carbon-In-Pulp ProcessDesign Criteria Commercial Operations Cyanide is a lixiviant, or reagent that is used to leach, often in tanks,goldfrom a solid matrix and form agoldcyanide complex. Thegoldcyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a ...
The single-pass extraction efficiency ( E) is relatively constant throughout the elution cycle and an average value of E = 0.9 has been found to be typical of cells operated with the Zadra elution owing to the high solution conductivity (>8 Sm –1) and high eluate temperatures (80°C).

Froth flotation is generally limited to size fractions betweenroughly 65and100 mesh. Particles larger than65 meshTyler (210 micron) are difficult for the air bubble to lift while particles smaller than400 mesh(37 micron) often will not attach to the air bubble.
Xstrata Technologyconsiders “the most noticeable has been the increase in sizes of theflotationmachines, from the multiplesmall square cellsthat were initially used, to the300 m³ round cellsused today that are the norm in large scale plants.
Froth level and froth to pulp interface. The level of the froth and the froth/pulp interface are one of the key factors for the process. We recommend using a Prosonic interface measurement transmitter with two ultrasonic sensors if instruments can be installed at the top of the tank in combination with an XPSFloatTM system consisting of a PTFE coated conical float, a teflon rod and a target plate.

Cordoba et al. (2008) have shown that the passivation ofchalcopyriteis related tohighpotential value (e.g.highFe 3+ /Fe 2+ ratio). It was concluded that the leaching solution of ferric/ferrous sulfate reach rapidly an equilibrium at which the activities of both ions are equal and related to a critical potential of approximately 0.65 V vs SHE.
