In many parts of the arid zone of Western Australia, regolith overburden is characterised by high levels of salinity and or sodicity (Osborne et al. 1996). In addition, on base metal mines, the overburden may still contain significant levels of the minerals of interest. In other cases, sulfide minerals in the overburden require special handling strategies to avoid acid mine drainage. Thus waste dumps containing overburden embrace a range of difficult constraints to revegetation. The chemical properties of two waste dump substrates derived from overburden and one sub-soil at Bulong Nickel Operation (BNO) were investigated to determine the nature of the material and its suitability for growth of the legume, Acacia acuminata ssp. burkittii and the salt tolerant blue bush, Maireana pyramidata.
