The DSI sandwich high-angle conveyors will serve as transfer conveyors elevating crushed pebble ore, each at a rate of 135 tph, and operating at an incline angle of 45°.

Buriticá is approximately a two-hour drive on the paved, Pan-American highway from Medellín, Colombia‘s second largest city. Highlights of the project include:

Maiden mineral reserve for the combined Yaraguá and Veta Sur vein systems total 3.7 million oz. of gold and 10.7 million oz of silver (13.7 million t grading 8.4 g/t gold and 24.3 g/t silver).

  • Gold and silver recoveries of 94.1% and 59.9% are expected, respectively, over the life of the mine (LOM).
  • A 14-year mine life will produce 3 492 000 oz. of recovered gold and 6 425 000 oz. of recovered silver.
  • This is the second gold project on which DSI has cooperated with M3 Engineering. In 2010, DSI executed a contract through M3 for an overland conveyor system at Goldcorp’s Los Filos project in the Nukay mining district of central Guerrero State in Southern Mexico.

DSI sandwich belt high-angle conveyors take on many forms and offer many advantages. Each DSI sandwich conveyor uses two-standard, smooth-surfaced conveyor belts, face-to-face, to gently but firmly contain the product being carried. This not only makes steep angles possible; it also offers a spillage free, environmentally sound operation because the material remains secured between the belts.

A DSI sandwich conveyor is capable of higher conveying speeds and greater capacities than other high angle conveying methods. With the availability of wider belts and accompanying hardware, capacities greater than 10 000 tph can be easily achieved with a DSI sandwich conveyor. High angles of 90° are typical, and lifts of 300 m are easily accomplished.

The use of all conventional conveyor parts ensures high availability and low maintenance costs, as well as interchangeability of components and fast delivery of replacement parts.
