Dos Santos International is pleased to announce the award of a contract to provide two DSI Sandwich belt high angle conveyors, in cooperation with M3 Engineering, Tuscon, AZ USA for Continental Gold’s Buriticá project in Antioquia, Colombia. The DSI Sandwich high angle conveyors will serve as transfer conveyors elevating crushed pebble ore, each at a rate of 135 t/h, 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. Some highlights of the project are noted below:
- Maiden mineral reserve for the combined Yaraguá and Veta Sur vein systems total 3.7 million ounces of gold and 10.7 million ounces of silver (13.7 million tonnes 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 ounces of recovered gold and 6,425,000 ounces 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 t/h can be easily achieved with a DSI Sandwich conveyor. High angles of 90° are typical, and lifts of 300m 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.
