During the first phase of the project two new Bateman Pulsed Columns were installed, while the second phase focused on the modification of the existing plant by relocating two of its Bateman Pulsed Columns supplied in 1997. The copper-uranium deposit at Olympic Dam is the world’s sixth largest copper deposit and the world's largest uranium deposit.

The $12M design, procurement and construction contract proceeded on a cost-plus fast-track basis. WMC selected Bateman Pulsed Columns because of its successful previous experience with the technology, the low capital requirements and the inherent safety advantages compared to mixer settler technology.

The two new pulsed columns, which are 16 m in height and 2,5 m in diameter, were fabricated offshore and delivered to Olympic Dam within three months of the first discussions. The columns were constructed using fibreglass reinforced polyester (FRP) with special carbon- fibre layers on the inside and outside surfaces. These layers were designed to prevent the build-up of static electricity, thereby eliminating a potential fire hazard.

WMC’s new engineering standards were incorporated into the columns to minimise fire risk. Existing piping materials were replaced and the engineering design was completed to the required standards for areas considered to be hazardous. 
Bateman Litwin is currently the only global supplier of pulsed-column technology with proven commercial applications in the mineral- processing industry.
