Denmark: FLSmidth recorded consolidated sales of Euro1.67bn in the first nine months of 2021, up by 2% year-on-year from Euro1.64bn in the corresponding period of 2020. The supplier recorded a net profit of Euro26.4m, up by 54% from Euro17.1m. Of its two divisions, its cement business’ sales increased more sharply, by 22%.

CEO Thomas Schulz said “The third quarter of 2021 saw strong momentum in order intake. The cement industry is emerging from the pandemic with improved service activity and growing demand for greener solutions. Revenue grew strongly and earnings before interest, taxation and amortisation (EBITA) increased by 72% with an improved EBITA margin in both mining and cement.” He added “Our cement reshaping activities have progressed well and EBITA in cement was positive for the first time since the first quarter 2020.”

Volvo Autonomous Solutions and Holcim Switzerland announced this week that they are testing and developing the use of autonomous electric haulers in a limestone quarry. It’s a two-part project, as being able to run electric dump trucks will help Holcim to meet its sustainability goals by switching to renewable energy supplies. Automating the control of the trucks then lets Holcim work towards its digitisation targets as part of its ‘Plants of Tomorrow’ initiative. Holcim Switzerland has also been running a drone programme at the plant (see GCW520) and has been using a few electric concrete mixer trucks since early 2021.

The use of autonomous haulage systems (AHS) in quarries by the cement industry seems to mark the start of something new. As far as Global Cement Weekly can tell, the Volvo Autonomous Solutions - Holcim Switzerland project is the first one in the cement sector that has been announced publicly. Most of the examples of AHS to date have been for heavy mining applications such as iron ore, copper, oil sands and coal. Automation in limestone and aggregate extraction has been slower. One recent example in the aggregate sector was announced in late 2020 when Norway-based technology company Steer said it had signed a contract with Romarheim to supply three autonomous dump trucks for use in a stone quarry. Previously Steer has used its vehicles to clear unexploded ordinance for the Norwegian army.

AHS have been around commercially since the mid-2000s when Komatsu tested and then deployed one at a copper mine run by Codelco in Chile. By September 2021 Komatsu said it had commissioned over 400 trucks with its autonomous system and that these had hauled over 4Bnt of materials. For its part Caterpillar says it started its first automated vehicle research program in 1985 and was even testing a pair of Cat 773 dump trucks in the 1990s. However, it then took a pause before resuming after 2000 and starting its commercial projects in the 2010s. In April 2020 it hit 2Bnt of hauled materials by AHS using its MineStar Command product. Hitachi, Liebherr and Belaz have also been working on their own AHS products in conjunction with third party technology providers and these were developed later in the 2010s. Most of these products are complimentary control systems that have been added to existing models or can be added to new ones. Autonomous vehicle company ASI is the other big name in the field with its Mobius product. Unlike the other systems, this is purely a retrofit product. ASI does not make its own vehicles. Komatsu and Caterpillar have also developed retrofit kits for their systems.

Most of the products above look mostly like normal trucks with the addition of extra kit. Volvo and Scania have also been working on AHS but their products have been taking it further by removing the cab entirely. Scania launched its AXL product in September 2019. Volvo launched its Volvo Autonomous Solutions subsidiary in 2020 and its Tara system electric dump truck the same year. Volvo had previously planned to run a pilot for its Tara truck with Harsco Environmental carrying slag at the Ovako Steelworks in Hofors, Sweden. Unfortunately the pilot was disrupted by the start of the coronavirus pandemic shortly after it started.

It’s early days yet with the use of autonomous vehicles in the quarries of the cement and aggregates sectors. Obvious advantages are additional operational hours, better worker safety and reduced costs. As ever with automation, cutting out human jobs would be one disadvantage for the current workers at least. There is also the possibility that an experienced human driver using efficiency software tools might be better than a fully AHS. A challenge in the field is developing open standards or methods to allow autonomous machines to communicate or work with both products by the same manufacturer and its rivals, as well as with conventional human-driven ones. Another challenge is for the mining and quarrying industry to determine how flexible it wants its heavy vehicles to be. One thought to end with this that an autonomous vehicle with a cab and a steering wheel can still be driven by a human. The cab-less vehicles being tested by Volvo and Scania would be rather less useful if they get into a situation where the software can’t cope. Lots to consider.

Switzerland: Holcim Schweiz has partnered with Sweden-based Volvo Autonomous Solutions to test and develop automated electric dumpsters at its Gabenchopf quarry in the Siggenthal. The companies aim to develop a safe, efficient and sustainable dumpster for use in the cement industry.

CEO Simon Kronenberg said “We are very excited to be working with Volvo on this project. For us, this project means a further step towards realising our sustainability goals: in order to make a contribution to a sustainably built future, we continuously invest in measures to reduce our ecological footprint and look for solutions that are both innovative and sustainable."

Kazakhstan: Korcem, a joint venture of International Cement Korday and Nurzhan Shakirov, plans to invest US$150m in the upcoming 1.5Mt/yr Korday cement plant in Zhambyl region. The company has a mining licence for 11ha of land in Korday district. International Cement Korday, a subsidiary of Singapore-based International Cement Group, holds 88% of shares in the venture. The plant is scheduled for commissioning in mid-2023.

India: Denmark-based FLSmidth has agreed with Germany-based ThyssenKrupp to exclude the latter’s mining activities in India from the final deal in its acquisition of ThyssenKrupp Mining. This reduces the total cost of the transaction by 14% to Euro280m from Euro325m. FLSmidth said that the exclusion of the Indian business will not affect the transfer of its key intellectual property and technologies to the supplier as part of the overall transaction.

Australia/UK: InterGroup Mining has secured just under Euro60m from Luxembourg-based investment group GEM Global Yield as part of a share subscription facility. The Australia-based mining company says it will use the funds primarily for the ongoing development and commercialisation of its Brilliant Brumby kaolin and gold project in Queensland. The company hopes to sell the kaolin for use in cement and concrete production or as a feedstock for high purity alumina (HPA). It says it will be able to drawdown the funds over a 36-month term following a public listing of its common stock.

Neil Miller, the chairman of InterGroup said, “The GEM facility provides a major accelerator for InterGroup as we continue to prove up the scale of our Brilliant Brumby project and the optimal development path for the co-mining opportunity of kaolin and gold. It likewise enables us to continue our important research and development work into the new carbon reduction markets of potential scale that our minerals serve and which complement their existing known end markets.” InterGroup is currently working towards a potential stock market flotation in the second half of 2021.

Denmark/Germany: FLSmidth has agreed to buy ThyssenKrupp Industrial Solutions’ mining business (TK Mining) for Euro325m.
