The aim of this project is to assess the further enhancement of value to the Carrapateena copper concentrate.
The current Carrapateena plant design utilizes a standard bulk sulphide flotation process to produce a high grade copper gold concentrate – as such the copper grade of the flotation concentrate is dependent on the sulphide mineralogy of the feed, which changes over the life of the mine.
Areas of higher bornite and lower pyrite mineralization generate higher copper grades, and areas of lower bornite and higher pyrite content will result in a reduction in copper concentrate grade.
The ability to reject pyrite from the copper concentrate - without excessive losses in valuable minerals - increases the overall project value. The project will study the process and economics of these opportunities.
