Antapaccay Copper Mine Mining Technology Mining News and ...

The Antapaccay copper mine is a part of the Tintaya district, which is filled with Cretaceous sedimentary rocks and monzonitic plutons. The rocks contain copper bearing minerals, such as the bornite, chalcopyrite, chalcocite and copper oxides. Antapaccay consists of a sulphide mineralised system with limestone filled rocks containing chalcopyrite and bornite in altered quartz monzonite and diorite form. The upper part of the deposit is made up of mineralised exoskarn areas, copper carbonates and copper oxides. Antapaccays JORC compliant ore reserves for the year ending 2011 12 are 541 million tonnes at 0.59% copper, 0.13% gold and 1.51% silver.

The mine consists of two pit operations and a concentrator plant. The concentrator plant, which consists of a semi autogenous grinding mill and two ball mills, can process 70,000 tonnes of copper sulphide ore per day using crushing and rotation. Concentrate is thickened and filtered at the mine before trucking it to the port for export. Flotation tailings are sent to the tailings thickening plant using the gravity flow.

Antapaccay copper mine is equipped with a gearless belt conveyor system featuring Siemens drive system. The system was developed by Siemens in collaboration with the ThyssenKrupp. Antapaccay is only the second mine in the world to be installed with the belt system. The belt is 1,370mm wide and has a conveyor speed of 6.2 metres per second. The conveyor system includes two slow speed running synchronous motors with a power of 3,800kW. It offers more reliable and efficient operations at reduced costs compared to normal conveyor systems. The gearless drive system of the 40ft SAG mill has a power rating of 24MW and the two 26ft ball mills have a power rating of 16.4MW each.

The construction of Antapaccay mine created approximately 4,250 jobs. It is also expected to create approximately 1,400 permanent jobs. Antapaccay will use existing infrastructure at the in operative Tintaya mine. The shared infrastructure will include the fuel tanks and refuelling system, drinking water supply, office and buildings and mining trucks and shovels. The Tintaya open pit mine will also be used as a tailings storage facility for Antapaccay.

The engineering, procurement, construction and maintenance contract was awarded to Bechtel. ThyssenKrupp Robins was awarded the contract for supplying the conveyor system. It sub contracted the same to Siemens. Siemens was awarded the contract to supply three grinding mills and a gearless belt conveyor system. The supply included entire switchgears and gearless drive system for the SAG and ball mills. ABB was awarded the contract to supply two synchronous condensers and harmonic filters for the Antapaccay project. It also supplied harmonic filters and controllers, condenser systems, distribution transformers and excitation and protection panels.

Toquepala Copper Mine, Tacna province, Peru

The Toquepala group has deposits of the Cretaceous and Lower Tertiary period, which date back to 60 to 100 million years. The mine includes a group of volcanic rocks of spills and pyroclastic andesitic, dacitic, and rhyolitic with intercalations of thick sediments of 1,830m emerging along the Andean flank. These formations are intrusive rocks of the Andean batolith and present various degrees of metamorphism and mineralisation. It overlaps the Yura group formation and there are no traces of fossil fuels. Among several deposits, the prominent intrusive rocks found in the area consist of granodiorite, coarse to fine grain holocrystalline, granite, and holocrystalline. Ore minerals found at the mine include chalcopyrite, chalcosine and molybdenite. Toquepala is estimated to contain approximately ten million tonnes of copper reserves.

Open pit mining at the deposit is performed up to a depth of approximately 1,635m. Once the ore is mined, it is sent to the concentrator for recovery of copper and molybdenum. The nominal capacity of the concentrator is 60,000 tonnes per day. Mined ore with a copper grade of more than 0.40% is sent to the crushing circuit, where the size is reduced by approximately 85%. The crushed ore then passes through rod and ball mills, to produce a fine powder. The finely ground powder is mixed with water and sent to flotation cells to produce a copper concentrate. Any molybdenum content in the concentrate is recovered by inverse flotation. The final copper concentrate containing approximately 26.5% of copper is filtered and sent to the Ilo smelter. The Ilo smelter is located near the Pacific Coast in the Ilo district, approximately 135km from Toquepala mine, which is used by both Cuajone and Toquepala mines. The Toquepala SX EW plant produces grade A electrowon copper cathodes with a puri...

Several expansion and infrastructure upgrades based on production requirements and maintenance of safety standards were implemented at the mine. The recent upgrades included the installation of 20m wide geotechnical berms for every 10 benches in 2007 to strengthen the stability of the mine. In addition, geotechnical drilling totalling 20,000m in 2013 was completed. Further, a slope stability programme was implemented for geotechnical and hydrological oriented drill programme of 11,451m in 2015. The construction of first molybdenum plant was completed in 2013 as part of the expansion programme. The expansion project allowed the concentrator facility to process 1,500t of copper molybdenum concentrates per day with a recovery of 80% of copper content and 50% of molybdenum content. Another expansion project was undertaken in 2015 at an estimated investment of £889m for the expansion of the concentrator to increase the production capacity by 60,000t. The expansion project also i...
