Introduction. Leaching of ores by cyanide in aerated alkaline slurries has been the dominant process for gold extraction for more than one century. In order to accelerate the gold recovery in most of the high-grade ore plants the cyanidation process occurs continuously in a cascade of large agitated tanks. The reactor volume optimization is a ...

Cyanide leaching of gold is carried out in very large mechanically stirred tank reactors. The reactor size can be up to 5000 m. A typical agitator configuration is two downwardpumping hydrofoil impellers which requires a low mixing power input and results in low shear rates inside the reactor.
Leaching reactor Combining long-term production value with low operating costs the Leach Reactor is installed after concentration in a circuit to maximize gravity treated ore. Extensive test work of the Leach Reactor on site has shown over 99% of the target mineral is recovered through a simple fully automated process that is easily incorporated into gold and silver recovery operations.
The reactor is called the Albion Leach Reactor. The Albion Leach Reactor consists of the following components: A corrosion resistant alloy steel tank and base supported on a ring beam foundation.
Improving the process performance of gold cyanide leaching reactors 3 literature Equation 1 shows that k L a is a function of mixing power intensity P/V and superficial gas velocity v s. The coefficients A B and C are reactor- and appli ion-specific. k L a = A
Whereas PFR/tubular reactors are continuous reactor where input of and output of product are continuously and PFR /tubular reactors are used for the gold leaching from ore. CSTR is known as back mix reactor which is most common ideal reactor type in chemical engineering. It may be continuous or batch type Reactor.

Cyanide gold leaching in Pachaca Tanks Pachuca-Tank Milling-and-Cyanidation-at-Pachuca Pachuca Agitator The tank is circular in shape and equipped with a 60 conical false bottom and a central air tube which is approximately 1/10 of the diameter of tank.
Gold received after the second precipitation has lower quality and is recycled to the leaching tank for refining. This way the purity of the precipitated fine gold is maintained at a high level. The filtrate received after the second gold precipitation is sent for recovery of PGMs.
Intensive Cyanidation Reactor by Resources Gold Technology Intensive Cyanidation Reactors ICR are used primarily for the gold leaching of high grade concentrates such as gravity concentrates. While appli ions exist for low volume high grade refractory gold ores operational costs make intensive cyanidation reactors most viable on higher grade concentrates.
