tank leaching application

Tank leaching - Wikipedia

Tank leaching is usually differentiated from vat leaching on the following factors: 1. In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;

What Is Tank Leaching? - wiseGEEK

01/04/2020  Tank leaching is a process used to extract trace metal from ore. In this technique, ground ore is mixed with a reagent inside a tank to form a slurry, allowing the metal to separate out so factories can recover it. The remaining materials in the tank may be recycled for more processing or disposed of, depending on policies at the facility and the chemicals involved. One concern with tank ...

High grade, fast leaching ore would be readily accommodated by an agitated tank leach, whilst low grade, slow leaching ores would be better suited to heap leaching. Depending upon the product desired, there may be no need for a solution purification stage, further simplifying the overall process flow sheet. A wide range of different oxide zinc mineralogies can be treated by AmmLeach ...

THE APPLICATION OF BIOLEACHING TO BASE METAL SULFIDES IN ...

There are two ways to design a bioleaching process: either by tank leaching of a milled material – usually a sulfide concentrate produced by flotation – or by heap leaching of a crushed sulfide ore. There are variations to this theme, including indirect leaching (in which the leaching and biological growth processes are conducted separately), dump leaching (on uncrushed run-of-mine ore ...

How to Fix Mixing Problems in a Gold Leach Circuit

This design problem caused solids to build up around the walls and bottom of the leach tank, reducing the effective size of the tank and lowering the actual leaching time for the active slurry. This reduction in leach time ultimately resulted in lower gold recovery. - To get more agitation, the impellers were sped up.

solids content in tank leaching is kept at a high level, around 40 wt.%. Currently, a typical agitator configuration in a cyanide leaching reactor is two downward-pumping hydrofoil impellers, as illustrated in Figure 1. Hydrofoil impellers generate a highly axial flow pattern for a low power draw. This makes them a good choice for most solids suspension mixing applications (Seal and Kehn, 2013 ...
