Heap Leaching of oxide type ore (4 replies and 1 comment)

Hello everyone,

For the heap leaching of oxide abrasive ore without clay particles, I could not reach any information about crushed ore size estimation. So,what should be the crushed ore size to feed to the heap leaching ? Could you please also give reference ?

 

Thanks in advance.

I´m not an expert on it, but for sure has to be related of how exposed the valuable particles are, if the exposure grade is high, just a personal opinion, there is no need of an excesive grinding of the material.

Every operation is different, that´s why I think it will be good for you the characteristics of the mineral you´re processing.

normally each ore is different from another relative to the exposure of the valuable mineral targeted, for example gold is free at size range from 10 to 25mm in highly oxidized ore. and a recovery of around 70% can be reached . However I suggest you do several column test for different sizes to obtain the best recovery at the least cost.

Ditto Mutassim. Also, need to look at the porosity of the ore before and after the leaching. Specialized testwork needed for compete evaluation and overal (metallurgical / stability / enviornmental) risk assessment. Good luck.

Vat leaching by various sizes will also help with determining the optimal p80 for the material. This coupled with column testing and hydrodynamic testing can show the optimal application rates coupled with recovery.
