Golden con­tract for Ve­o­lia

DEMM Engineering & Manufacturing - - CON­TENTS -

Ve­o­lia Wa­ter Tech­nolo­gies, which has a 30-year contract to man­age and main­tain Pa­pakura’s (Auck­land) wa­ter sup­ply – a contract when first won that was the only pri­vate sec­tor wa­ter con­ces­sion contract in the coun­try – has been con­tracted to de­sign and sup­ply a Re­verse Os­mo­sis plant to re­duce the chlo­ride lev­els in the pro­duced wa­ter stream at the Foster­ville Gold Mine. The wa­ter treat­ment plant so­lu­tion will al­low Kirk­land Lake Gold to con­tinue meet­ing their op­er­a­tions li­cense con­di­tions in a sus­tain­able way.

Kirk­land Lake Gold is a mid-tier gold pro­ducer tar­get­ing 580,000 – 595,000 ounces of gold pro­duc­tion in 2017 from mines in Canada and Aus­tralia. In Aus­tralia, Kirk­land Lake Gold owns and op­er­ates the Foster­ville Mine, which is a high- grade, low- cost un­der­ground gold mine, lo­cated 20 km from the lo­cal city of Bendigo. The Foster­ville Mine fea­tures ex­ten­sive ex­plo­ration po­ten­tial and low­cost pro­duc­tion. The mine is cur­rently ex­pe­ri­enc­ing a sig­nif­i­cant in­crease in gold pro­duc­tion due to re­cent ex­plo­ration.

Foster­ville Gold Mine plans to im­ple­ment a wa­ter treat­ment plant to treat mine wa­ter for re­use within their process wa­ter cir­cuit and Ve­o­lia’s task is for its Re­verse Os­mo­sis plant to re­duce the chlo­ride lev­els < 500 mg/ L. The plant will con­sist of mul­ti­me­dia and car­bon fil­tra­tion fol­lowed by pri­mary Re­verse Os­mo­sis and re­ject re­cov­ery Re­verse Os­mo­sis. It has the ca­pac­ity to treat 2 MLD and will al­low the Foster­ville Gold Mine to con­tinue meet­ing their op­er­at­ing li­cense con­di­tions in a sus­tain­able way. It is planned to be op­er­a­tional in 2019.
