what is better for classification of copper up to 75 micron size whether to use spiral classifier or hydrocyclone

Down at 75 um you use cyclones for optimum particle classification.

A hydrocyclone has no moving parts, has a smaller footprint but is less efficient.

a spiral classifier has moving parts, a much larger footprint but is more efficient if correctly set up (feed density) weir height and calming zone.

if you have a spiral classifier, use it, if you do not have one, install hydrocyclones

If you want to do a classification based on grain size, hydrocyclone is the most appropriate. 

If you want to make a classification based on density (separation of two different minerals) spiral classifier is better.
