Haulage, emissions and energy intensity in copper concentrate production

Haulage, emissions and energy intensity in copper concentrate production

Norgate et al. (2010) researched available copper operations data that considered the energy intensity of a site for operations in Australia, Canada and Chile.1

The research determined that across industry there was generally a lack of data available that segregated energy intensity into the various stages within an operation in favour of reporting a single energy intensity across the whole operation. The study determined that haulage activity using diesel trucks makes up around 14 percent of whole of site CO2-eq emissions per tonne of copper concentrate with control parameters of copper ore grade being 1.8 percent, copper concentrate grade at 27.3 percent copper, and a copper recovery of 93.7 percent. This study highlights that haulage is a key operational activity that would benefit from a whole of industry effort to benchmark data, share and adopt practices and innovation to achieve a zero emission mining outcome.
