Parallel Session 9: Earth & Environment
- Richard Haverkamp (Massey Univeristy)
Increasing global demand for mineral and energy resources, coupled with declining ore grades, are creating growing global stockpiles of by-products including waste rock (~ 56 GT/yr) and tailings (~7 GT/yr). These are unusual geological materials, at extremes of pH and salinity, typically exhibiting elevated concentrations of elements and minerals present at otherwise low concentrations...
Australia is host to world’s 2nd largest copper deposits - yet it’s only the 5th largest copper exporter in the world. The copper industry in Australia faces significant challenges in mineral process owing to the complicated paragenesis of these copper deposits. Chalcopyrite (CuFeS2) is among the most common Cu minerals. The replacement of chalcopyrite to chalcocite (Cu2S) in a copper-rich...
Jarosites and related minerals are of great importance to a range of mineral processing and research applications. They are used in the removal of iron species from smelting processes; they occur in metal bioleaching systems, and in the desulphurisation of coal; they are present in acid mine drainage environments.
There has been a recent resurgence in interest in jarosite and associated...
