  • Improving the process performance of gold cyanide leaching ...

    Cyanide leaching of gold is carried out in very large mechanically stirred tank reactors. The reactor size can be up to 5000 m3. A typical agitator configuration is two downward-pumping hydrofoil impellers, which requires a low mixing power input and results in low shear rates inside the reactor. This results in an economically efficient process with low levels of carbon attrition, to thus ...

    Lime treatment was performed batchwise in a 60 gallon cone-bottom stirred tank where the pH was elevated to 10, and held for an hour. A sample of sludge from the operating treatment plant was also tested for comparison. The PLB/lime treatment was accomplished by first passing the water through the PLB system, followed by batch lime treatment to pH 10 as before. The sludge qualities were ...

  • Pachuca Tank - Mineral Processing Metallurgy

    In some Pachuca tanks, air is allowed to rise in a free two-phase flow jet to the surface of the slurry so a natural circulation pattern is set up in the pulp. In other tanks an axially located draft tube, typically 0.5 m (20 in.) in diameter, carries a buoyant air-slurry dispersion from the bottom of the tank to the surface of the slurry. Slurry flows back through the annular space between ...

  • Mixing Tanks for Agriculture - Tanks West

    Tanks West mixing tanks utilise axial flow impellers which discharge downwards towards the vessel bottom this creates a flow pattern across the floor of the tank and up the vertical walls. This flow vector then blends with the circular flow being created by the rotation of the blade to give even mixing of the entire contents of the tank. The batch turnover rate gives an indication of the ...
