:: Newmont Install ConSep ACACIA Reactor

The first North American installation of a ConSep ACACIA Reactor went online this month at Newmont's Golden Giant Mine. After only one trial run, the ACACIA system permanently replaced the shaking table circuit to maximize gold recovery from the high-grade gravity concentrates produced from existing batch-type Knelson Concentrators.

Golden Giant Metallurgist Gerry Barstad, who performed the original lab scale and pilot test work on the ACACIA unit, spearheaded the project. "We had a very high comfort level with the ACACIA Reactor since we've done extensive testing with the Acacia 50 pilot plant prior to ordering the unit," said Barstad. "Results from the full scale unit were very impressive from the start and were right in line with our expectations from the pilot program. Our goal now is to optimize the unit and maximize our gravity recovery," added Barstad.

The ACACIA's first week of production produced an average gold recovery of 99% from Golden Giant's Knelson Concentrators.

The ConSep ACACIA Reactor is a patented, high-efficiency leaching system exclusively designed to handle the high-grade concentrates produced by Knelson Concentrators. The system is designed to maximize gold recovery from gravity concentrates and provide numerous process advantages over a conventional gold room.
