Oct 19, 2020 However, the move to mining sulphides and associated requirement for a concentrator will require a desalination plant. Water supply issues are nothing new for Chilean copper mining operations. In 2015, a prolonged drought forced water restrictions on Los Bronces, resulting in an 18,000 t reduction in copper output.

OHL has been awarded a new contract in Chile, worth close to 150 million, which includes engineering, construction and commissioning for the conversion and expansion of the copper sulphide processing plant at the Mantos Blancos concentrator, in Antofagasta. The project includes the revamping of the existing oxide line, the construction of part of a new sulphide line and the implementation ...
Leachable reserves total 336 million tons with an average copper grade of 0.3 percent. They are treated at a solvent extraction and electrowinning SX-EW plant located to the east of the Concentrator Plant, in the upper sector of the Caserones Ravine. Copper cathodes are produced by PLS solution processing at the Dump Leach.
It operates the Toquepala and Cuajone open-pit mines, and a smelter and refinery in Peru and La Caridad, an open-pit copper mine, as well as a copper ore concentrator, a SX-EW plant, a smelter ...
Copper ore is mined in the X41 and Enterprise underground mines, where it is roughly crushed, then hoisted to the surface for processing. From here, it is fed through a series of ball mills that grind the rock into a fine dust. This dust is then mixed with water and reagents in the concentrators flotation circuit.
Ausenco provided engineering and procurement services for the sulphide concentrator to produce copper and molybdenum concentrates. Achievements. One of the largest concentrators Ausenco has designed. The design was leveraged off the concentrator design Ausenco developed for the Bozshakol Project, saving the client considerable man-hours and costs.
Sep 01, 2019 1. Introduction. The concentration of sulfide copper minerals by means of flotation generates large volumes of tailings. It is estimated that one hundred twenty-five tons of tailings are generated per one ton of produced copper, and its generation is on a continuous rise because of the decrease of the copper grades .On the one hand, the tailing is considered an environmental problem
Copper production from oxide ore is declining and is due to fall quickly in the coming years. As a result, CODELCO is developing the lower grade sulphide reserves to extend mine life to 40 years by accessing 2.67 Bt of mineral resources grading 0.47 copper. A new 100,000tpd concentrator plant is part of the plan with ramp-up beginning in 2019.
Oct 26, 2020 Major construction works carried out at the Bozshakol copper project included the concentrator building, a 200kV power line and a permanent accommodation camp. Approximately 15,000t of structural steel, 10,000t of re-bar and 90,000m of concrete were used for constructing the concentrator plant.

Fluor built the original copper mine, processing plant, support infrastructure, and the Coloso port near the city of Antofagasta. The project in the Andes Mountains included a copper concentrator, crushing and conveying systems, a camp and onsite facilities, and a 200-km power transmission line.
