Abstract. The copper grade in the Aitik mine in northern Sweden is decreasing, therefore other deposits are investigated. One of these deposits is the satellite deposit discussed in this thesis. The grade of this deposit is higher than in Aitik and could thus be used to increase the copper production at the Aitik mine site.

All told, the team’s analysis suggested that adjusting the mill’s controls to suit each of the seven ore types could increase copper production by 10 percent or more. That prospect convinced Freeport-McMoRan’s leaders to let the agile team at Bagdad build an AI model that would look at the ore coming into the mill and suggest control

Aitik has been wholly owned by Boliden since the consolidation of Outokumpu’s copper and zinc mining and smelting activities into New Boliden in January 2004. Boliden approved the investment of Skr5.2bn ($790m) for the expansion of the operations (Aitik 36) in 2006. The project was completed in the second half of 2010 at a cost of Skr6.1bn ($865m as per 29 September 2010 exchange rates). On average, ore is mined at a rate of 1t per man hour. Production at Aitik was 43t man hours. With the comple
