SUMMARY<br />
In summarizing the information just presented, we find<br />
that a reasonable amount of care should be exercised at each step<br />
of handling petroleum coke. It is recongnized that some of the<br />
physical properties (sizing) of a calcined coke can be destroyed<br />
if the cutting operation is not carried out properly. .Also sources<br />
of contamination should be avoided in order to keep the iron and<br />
silicon content within required limits. Where a carbon aggregate<br />
with low silicon or low iron is required a selection can be made<br />
from a given shipment if the material is delivered in rail cars.<br />
