solid liquid separation of gold leaching liquid

Liquid–Solid Separation in Gold Processing - ScienceDirect

01/01/2016  Other liquid–solid separation stages in gold recovery circuits are clarifiers used to clean low suspended-solids streams. The mechanics of clarification are similar to those of thickening. The parameters of feed solids concentration, flocculant type and dosage are important to ensure collection of solids in larger masses that will settle to the underflow. The objective is enhanced overflow clarity,

Solid-Liquid Extraction (( Leaching

Solid-Liquid Extraction ((Leaching )) Leaching: is the separation of a solute from solid mixture by dissolving it in a liquid phase. Leaching occurs in two steps: 1. Contacting solvent and solid to effect a transfer of a solute (leaching). 2. The separation of the solution from the remaining solid (washing). Factors influencing the rate of extraction:

15/05/2018  Therefore, we propose the following solid-liquid separation methods to improve the reproducibility of leaching test results: (1) A fixed centrifugal intensity and fixed filtration volume per filter (area). This will generate reproducible results, even with filter cake formation or clogging during filtration. However, in this method, filters cannot be changed when filtration speed decreases. Therefore, (2) a fixed centrifugal intensity to avoid filter

Leaching process (solid-liquid extraction)

17/02/2016  Principle of leaching • Leaching can be batch, semi batch, or continuous. It usually operates at an elevated temperature to increase the solubility of the solute in the solvent. • Feed to a leaching system typically is solid, consisting of basically insoluble carrier material and a (usually desirable) soluble compound. The feed usually must be prepared by grinding or chopping. It is then mixed with a liquid

Heap leaching is the only leaching that needs a solid-liquid separation, with other leaching methods the pregnant solution goes straight to the clarifying tank. Separation uses the Counter Current Decanter (CCD) thickeners before being clarified. From the leaching tanks where cyanide solution is added to gold, the slurry is sent to the CCD tank, shown in figure 5 below, the pregnant solution ...
