SUMMARY

ROLLESTON COAL - GLENCORE REACTIVITY TEST NOVEMBER 2022 | GC17-11-22

Download Report

Results:                          

Table 1 Results for Testing using QMR Reactive Ground Test

Table 2 Results for Testing using AEISG Code of Practice

Prior to  testing as per the AEISG Code of Practice each sample was assessed for reactivity risk based on pH, carbonate and the amount of reactive sulphide  and coal using the QMR Reactive Ground Test (refer to Table 1 and Table 2 for results of both tests).  Three samples contained more than trace sulphide with Sample C123-97_ER01 the only sample containing more than 1% sulphide.  Sample C123-97_ER01 was inhibited by the 2coal which inhibited a reaction between the sulphide and nitrate when tested as per the AEISG Code of Practice

Conclusion:

All  samples were found not to be reactive when tested as per the AEISG Code of Practice and the QMR Reactive Ground Test.
