The purpose of this report is to provide information on the process and results from the calibration of the Allscan elemental analyser installed at Colombia.
The purpose of this test was to determine the suitability of the AllScan PGNAA Elemental analyser for use on iron ore quality measurement applications.
Four samples of XXXX Bauxite ore (labelled Hu1 thru Hu4) were tested at each of 4 different conveyor loadings (10,30,70,100 kg per metre) in the RTI AllScan Falcon 4X PGNAA test rig at Mackay
Four samples of COMILOG Manganese ore (labelled Samples 1 to 4) were tested in the RTI AllScan test rig at Mackay, Australia, with the purpose of determining how accurately PGNAA technology could determine elemental composition of important elemental components of the Manganese ore (typically Mn, SiO2, Al2O3, Fe, P and K2O).
Four samples of Ilmenite were presented for elemental analysis using the RTI Allscan PGNAA through belt test rig. The test was a preliminary one to demonstrate capability and measurement resolution for this application.
The samples were supplied by the client in three 200L drums. Each drum contained approximately 140kg of material.
Two drums of scrap metal were presented for Analysis using the RTI Allscan test rig PGNAA gauge.
The ability to quickly determine copper assay to high accuracy in a PGNAA gauge is a difficult technical challenge due to the proximity of peaks in gamma energy for copper to those of other common elements like iron and aluminium, and limitations on neutron flux available to a through belt gauge.
