Four reclaimer feasibility tests were conducted with used blast grit from the Long Beach Naval Shipyard. The results of these tests revealed that the organic material component of the used grit was fully oxidized to carbon dioxide and water. Some of the metallic oxides of copper, zinc, titanium, and lead from the used grit were largely elutriated into a cyclonic collector. The calcined (reclaimable) fraction from this test work amounted to approximately 95% of the used grit charged. The major oxide and organic component analyses conducted revealed no significant general chemical difference between the virgin and reclaimed grit. Based on these results, a commercial plant can be designed to provide a reusable grit yield in excess of 80% within the general size specifications. 2 refs., 4 figs., 9 tabs.
