[QUOTE="RotGrub, post: 161086, member: 5195"] My two cents... I run a recirculating highbanker and based on my system we need to classify to -1/2" before running the material as a general rule. However, I was taught to classify based on the size of gold to be recovered (not the size of the material). We sometimes use a 1/4" but the smaller you go the more time it takes to classify. The other thing you need to consider is not all classifiers are created equal. If you think you will be using it often then get a heavy duty one and not a cheap plastic or lesser quality steel one. The depth of the classifier is also a consideration as some are stackable (shallow depth) while the HD ones will handle more material and abuse. I was given a complete set of brass classifiers from a testing lab that start at 30 and go to 200. I use all of them in the winter to classify my concentrates before running them through a blue bowl. Every classification produces gold. [/QUOTE]
