Gravity Concentrations at Montana Tunnels

Mary Anne Antonioli, Bryon Darnton and Steve LLoyd
Presented at: Randol Gold Forum 96 - Resort at Squaw Creek - Olympic Valley, California, USA - April 21-24, 1996

August 14th, 1998

The gravity circuit at Montana Tunnels has undergone many changes since its production startup in July of 1991. After initial positive test work, a manual Knelson 30 inch concentrator was installed and soon thereafter the circuit was modified with the addition of another KC-MD30. With the introduction of the center discharge or "CD" units the circuit was further enhanced to incorporate a single CD unit with a manual unit as back-up. In March of 1994 the decision was made to move and expand the gravity circuit. New cyclones were installed with two screens, each feeding a KC-CD30. This paper examines the evolution of the Montana Tunnels gravity circuit and follows the benefits in both recovery and cost.

"I, with my assistant, Eduardo Baños, would be the first technicians in Argentina that experienced your Knelson lab unit. We got it from you through the Mining Secretary's Chief who visited your company in the 80s. We used it to learn new gravitational technology and we recovered gold and silver from melting furnaces scrap of Farallón Negro, YMAD, Catamarca province and from Abra Pampa melting plant (Berlingier Company), at Jujuy province..." ...more > >
