GRASBERG OPEN-PIT MINE
Welcome to the operating area of Freeport Indonesia, a mining company engaged in the exploration, mining, and processing of ore to produce fine sand containing copper, gold and silver, which are beneficial to human life.
This Virtual Tour presents 360-degree images of our operating area in Mimika Regency, Papua Province, Indonesia. We operate in a region with extreme and challenging natural conditions, and the company’s scale of operations is another aspect of the complexity of our operations.
Grasberg is situated at an elevation of approximately 4,200 meters above sea level. Grasberg is mined with the open pit method, which allows the use of large heavy equipment such as shovels and haul trucks in the excavation of material.
Freeport Indonesia conducts reclamation of areas impacted by mining activity. We also revegetate the areas with local alpine plants.
This is the Mega Shop where maintenance is performed on the fleet of haul trucks operating in Grasberg. The Mega Shop consists of 18 maintenance areas with the capacity to handle 280 trucks a month.
Freeport Indonesia is now ready to welcome the era of underground mining, as the Grasberg open pit mine will shut down operations in 2020. Freeport Indonesia’s active underground mining operation at this time is the Deep Ore Zone (DOZ) mining block. The Deep Mill Level Zone (DMLZ) and Big Gossan underground mines are undergoing preparation for operations, while future underground operations will also include Grasberg Block Cave and Kucing Liar.
You are now viewing the crusher area, where rocks are crushed at DMLZ block. DMLZ is located in the belly of the earth at an elevation of 2, 500 meters above sea level, at a horizontal distance of 5 KM and a vertical distance of 1.6 KM from ground surface.
Situated at an elevation of 2,500 meters above sea level, the Mill processes excavated ore through crushing, grinding and flotation, yielding concentrate slurry. The concentrate slurry is then transported to the Dewatering Plant in the Portsite area by means of a 114 km-long pipeline.
Tembagapura, a town above the clouds, is situated at an elevation of approximately 2,000 meters above sea level. It was built by Freeport from 1970 to 1972. The town was given the name Tembagapura on March 3, 1973, and is where most of our employees reside. Tembagapura is a town with high rainfall and a weather pattern of clear mornings and rain falling around dusk or at night.
Kuala Kencana is the town supporting our lowland operations, and was officially opened on December 5, 1995. Kuala Kencana is one the most beautiful and unique towns in Indonesia. The town consists of various supporting buildings, as well as a residential complex for employees and their families. There are also auxiliary facilities, including a healthcare clinic and a hospital, a school, a sports and recreation center, a shopping center, houses of worship, and even a golf course.
EMPLOYEE RESIDENTIAL AREA
Kuala Kencana is the first town in Papua equipped with an underground utilities grid for water and electricity supply, and collection and treatment of sewage and wastes.
MOZES KILANGIN AIRPORT
Mozes Kilangin Airport is the main gateway into Timika and Freeport Indonesia’s operating area. In addition to acting as supporting infrastructure for our operations, the airport serves commercial flights. The airport was first built by PT Freeport Indonesia in 1970 and underwent renovation in 2008 with more modern and better-equipped facilities.
CONCENTRATE STORAGE BUILDINGS
In Amamapare Port there is a concentrate Dewatering Plant where concentrate slurry from the Mill is dewatered until moisture content is 9%, after which the concentrate is placed in a storage facility.
The shipping of concentrate begins with the loading of dry concentrate onto a weighing area where the concentrate is weighed. The weighing area is also where concentrate samples are taken to undergo metals content analysis by the surveyor Sucofindo, which was appointed by the Trade Ministry. Elsewhere, the Customs and Excise Agency oversees the concentrate shipping process and ascertains all aspects of state revenue. The dry concentrate is then loaded aboard ocean vessels that will sail to smelter destinations in various countries in Asia, Spain, including to PT Smelting Gresik in East Java that was established by Freeport Indonesia.
