The 3DPM vision system has had quite a journey. Since the first prototype was installed at LKAB’s Malmberget iron ore to help the miner optimise its pellet production, the system has helped ‘settle the argument’ between mine and mill at base metal mines in Europe and improve the quality of coke being fed to blast furnaces in Japan

This mining method is based on creating cavities in the orebody through drilling and blasting, and allowing the ore to fall down to underlying levels by means of gravity, from where it is transported onwards by train or loader. When the ore is removed, waste rock …

ABB has won an order to supply a dual pinion high-speed ring-geared mill drive (RMD) system for LKAB’s latest grinding circuit expansion at the Malmberget iron ore mine in Swedish Lappland. The RMD system is designed in a bypass configuration, allowing LKAB to start two separate mills in sequence, compared to just one in the traditional setup

mining-induced deformation in the malmberget mine

The Norra Alliansen orebody of the Malmberget sublevel caving mine consists of iron ore interspersed with biotite schist and granitic inclusions. The schist is squeezed between the ore and the host rock and in direct contact with the ore along the majority of the length of the footwall. The schist exhibits high deformation when exposed to stress

Wassara water-powered drilling systems have enabled Swedish mining company LKAB to scale up its sublevel caving operation in the iron ore mines in Kiruna and Malmberget by approximately a factor of two. This is due to the fact that the Wassara system drills very long, straight holes, which results in well-fragmented ore after blasting

In 2019, Kiruna produced 14.7Mt of iron ore products. The production in 2018 and 2017 was 15Mt and 14.8Mt, respectively. The mine produced 50,000t of ore feed material a day in June 2020. Mining at the site was briefly halted in 2019 after an earthquake of magnitude 4.1, the country’s biggest-ever, occurred in …

The Hamersley Basin mining area lies in the Pilbara region of north-west Western Australia, 1,100km north of Perth. Through its wholly owned subsidiary, Hamersley Iron Pty, Rio Tinto operates five major producing mines in this area: Mount Tom Price, Marandoo, Brockman, Paraburdoo and Yandicoogina, while the company is in a 60/40% joint venture with the Chinese company, CMIEC, at the Channar

Apr 03, 2021 · The region holds huge reserves estimated at nearly 9 billion tonnes with a superior iron content of 65%. Analysts believe that the Simandou mine could produce as much as 150 million tonnes annually, which is equivalent to the 7% of the global production of …

Kiruna Iron Ore Mine, Sweden. With an ore body 4km-long, 80m-thick and reaching a depth of 2km, LKAB’s Kiruna is the world’s largest, most modern underground iron ore mine located in northern Sweden

Our underground mines. Ore is extracted from LKAB's underground mines by means of sub-level caving. The method is based on creating cavities in the ore body through drilling and blasting. When the ore is removed, waste rock collapses down and automatically fills the cavity. Sub-level caving is based on creating cavities in the ore body and allowing the ore to fall down to underlying levels by means of …
