Get PriceOn 1 August 2018, Kinross announced that construction was complete and that first ore had gone through the semi-autogenousgrinding(SAG)mill. Since then, themillthroughput increased from 8000 tpd to 12 000 tpd, representing a 50% increase. The mine estimates average annual production of gold to be 409 000 oz/yr through 2027.
Get PriceOther operations might reconfigure thegrindingcircuit entirely to operate without ballmills(i.e. in single-stage AG operation) to maintain production. What to address at your operation? ConvertingSAG millsto AGmillsbrings a new set of operating challenges to those lacking experience running AGmills.
