AGR is a joint venture between Wesfarmers CSBP Limited and Coogee Chemicals Pty Ltd which was formed to manufacture and market sodium cyanide. The AGR facility is located at Wesfarmers CSBP's fertiliser and chemicals complex in Kwinana (Figure 1). It currently operates two liquid sodium cyanide plants which have a combined production capacity of 50,000 tonnes per annum (tpa) of pure (100 percent) sodium cyanide, with the potential to expand to 70,000 tpa. These plants produce sodium cyanide as a 30 percent (by weight) solution. AGR is constructing a downstream processing plant that is capable of producing 25,000 tpa of solid sodium cyanide briquettes from liquid sodium cyanide.
