In 2015, TAKRAF as contracted to supply the principal ore transportation system moving crushed copper ore from underground storage bins to the surface processing site. The Chuquicamata mine, situated in Chiles north, has been in operation since 1915 and is owned by Codelco, Chiles state owned copper mining company.
The gigantic hollow is 2.5 km long, 2 km wide, and by the year 2030 will be 1 km deep. Every hour, the belt moves 8,700 t of ore out of the mine and down to the processing plant, which is located at an altitude of 1,600 m. This massive volume of ore is large enough to fill some 200 heavy duty trucks.
In the first half of 2018, it produced 205 thousand Mg of copper in concentrate, 640 Mg of silver in concentrate, 478 Mg of metallic silver, as well as 171 and 56 thousand Mg of electrolytic copper from its own and purchased concentrate, respectively.
copper ore, gypsum, slag, excavated silts, sands, clay, grains, refuse and municipal sludge, among other materials. The HAC system has taken the sandwich belt concept, and turned it into a highly reliable materials handling workhorse the result of specific engineering breakthroughs. One of the secrets to the high performance
In 2019, the Chuquicamata mine one of the largest copper mines in the world was converted from an open pit mine to an underground operation. In 2015, TAKRAF was contracted to supply the principal ore transportation system moving crushed copper ore from underground storage bins to the surface processing site.
