Assessing the energy and greenhouse gas footprints of ...

This situation will be exacerbated by any future decline in laterite ore grades and also by the imposition of a price on carbon, either by carbon taxes or emissions trading schemes. Some potential opportunities to improve the energy and greenhouse gas footprints of nickel production from laterites have been identified in the paper.

The Caron process was developed in the 1920s. In this process, the ore is dried and milled, then roasted in a reducing atmosphere to convert nickel and cobalt to their metallic form. Nickel and cobalt are then leached in ammoniacal solution but some losses occur due to adsorption and co-precipitation with iron oxide or hydroxide precipitates. The effects of various parameters on iron ...
