Leach Clarification Pressure Leaf Filters For Gold Mining Filtration

Durco Filters Leach Clarification Pressure Leaf Filters were developed, for the mining industry. In gold mining these units have been specifically optimized to produce clear leachant for input to the Merrill-Crowe gold recovery process.

Following Heap Leaching of gold ore, the resultant cyanidic leachant, containing dissolved gold, is referred to as being 'pregnant' with gold. However, it also contains fine sediment particles and other debris from the ore, which must be removed during the 'Clarification' step.

Durco Filters Leach Clarification Filter Media

Durco Filters Mining Filtration Engineers can deploy laboratory testing to define the optimum filter media for your particular extraction operation. Critical factors include the size and model of your filter unit, your process stream solids loading, your particulate size range, etc. In typical leach clarification applications, smaller filter units can utilize 3-Ply metallic mesh media (including drainage member), whereas larger units generally require 5-Ply media construction.

Example Durco Filters Leach Clarification Pressure Leaf Filter Unit

A typical example for gold mining applications is the Durco Filters Model HC Leach Clarification Pressure Leaf Filter with Sluicing (Wet Cake) Discharge, utilizing DE Pre-Coat over PolyPropylene-Covered 5-Ply Metal Mesh Media:

Durco Filters Mining Filtration Equipment Has Evolved Through Decades Of Design & Engineering Experience In The Mining Sector To Provide Clearly Superior Performance In Your Gold Extraction & Recovery Operation

Continuous Operation is typically achieved in most ore processing operations by deploying a minimum of 3 Leach Clarification Pressure Leaf Filter units. 2 Filter units run online, while the third unit is being cleaned and DE precoated for it's next filtration operation cycle.

Following clarification, in the absence of a Carbon Adsorption Gold Concentration Step, the clear pregnant leach solution is now ready for input to the Recovery Stage of the gold extraction process. The ore solids that were removed from the leach solution by the Clarification Pressure Leaf Filters are currently usually sent to the tailings pile in most gold mining operations.
