Research the filtration properties of the ore (1 reply)

Hello colleagues!
Anyone can suggest a method of laboratory research of ores before heap leaching? I am interested in the method of determining the height of the heap. I saw a device that allows you to simulate a column of ore height of 9-12 meters. Such a device is called: compression system? Can anyone suggest how to conduct an experiment?

Hi Mikhail,

I suspect that you are rather looking for percolation response, as heap leaching specifically precludes the need for filtration, that being its key benefit. Complete Heap leach testing  involves  metallurgical, hydrodynamics, geotechnical  and environmental components. The metallurgical component is straightforward, as it involves an amenability sub-component done by bottle-roll testing  followed by column testing. If you are leaching gold, you need to run some agglomeration and percolation tests as well prior to the columns tests.  You can do all this on your own eventually. On the other hand, for simulating multi-lift compression scenarios with columns in series and using compression forces to simulate virtually any practical heap height (10 m - 80 m+) I would recommend a specialized lab. Consider also validation by hydraulic conductivity data. Best, Alex.
