Sorting of residues 

Post processing, all residues, flots and finds are quantified and bagged separately.  

If required residues can be fractionated and sorted for ecofacts, artefacts and micro-artefacts.  Endocott sieves (xxx) are used to divide the residues into fractions of 0 – 2mm, 2 – 4mm and >4mm. 

A course sort is carried out on the >4mm residue portion to ensure total artefact retrieval.
