Establishing long-term relationships with universities to create smart technology is helping Rio Tinto slash idle time in operations

Rio Tinto is a powerhouse multinational mining and metals company based in the United Kingdom. They have operations on six continents and own a slew of mining operations through a complex web of wholly and partly owned subsidiaries.

The mega-successful Rio Tinto has thrived in the mining industry by continually developing new and efficient ways of improving its operations. The company has launched a diverse range of initiatives intended to enhance productivity as well as investing in partnerships and innovative technology. These investments aim to increase energy efficiency and capital productivity, but also improve processes and operator safety, along with extending the life of a resource.

Smart Technology

Through the years, Rio Tinto has worked meticulously to improve idle time in operations. Recently, the company rolled out a new rail technology in the Pilbara region of Western Australia that will greatly assist in this purpose.

The new technology for Rio Tinto’s 1,500km rail network, which connects its 15 mines and three port facilities, will allow train to drive at optimum speeds as well as improving its handling capability, and reducing braking distances and delays. The company has fitted its 173 locomotives on the network and more than 10,500 ore cars with the time-saving system.

Rio Tinto is also working to install AutoHaul™, the world’s first fully autonomous, heavy-haulage, long-distance railway network. The project will vastly benefit productivity, fuel efficiency and safety.

The company has also incorporated Driver Assist, a monitoring and control system that uses smart technology known as LEADER (Locomotive Engineer Assist/Display Event Recorder). The system monitors a massive amount of “live” track information and conditions, displaying it to the driver in real-time.

The system monitors information such as:

  • track geometry, such as the gradient or curve
  • projected speeds ahead of the train in relation to signals and speed restrictions 
  • the properties of the braking systems 
  • monitoring and reporting to the driver the in-train forces

The smart technology will not only improve transportation times for the railroad, but reduce the time needed for driver training.

Mine of the Future

In 2008, Rio Tinto launched its Mine of the Future™ program in search of new avenues for improving productivity and efficiency in mines. The three key objectives of the program circled around: autonomy and achieving massive efficiency in surface bulk mining; increased efficiency in recovery by sorting waste before it reaches the processing plants; and tunneling faster to reach orebodies in less time. Through technological advancements, Rio Tinto believes this plan of action can be easily accessible.

At the company’s Kennecott Utah copper mine, Rio Tinto has began testing a new technology called Copper NuWave™, a mineral-sorting process that maximizes ore recovery while reducing waste. The technology uses microwaves to stimulate copper species within individual rocks, allowing a computer to determine the rocks’ copper content. Rocks rich in copper are processed while rocks containing low or no copper are discarded. The computerized process will radically speed up ore processing times as well as cutting out a considerable amount of water and energy consumption involved in the crushing and processing system.

Rio Tinto’s head of Innovation, John McGagh, said: “Copper NuWave™ is a good example of efficient and responsible mining, and will provide Rio Tinto with significant benefits as copper grades decline worldwide.

Working together

Rio Tinto is involved in wealth of partnerships with educational institutes. The company has partnered with the University of Nottingham to form the Rio Tinto Centre for Emergent Technologies program. The five-year, multi-million dollar program seeks to establish new technologies for improving ore processing times. The company has worked with the University in the past, including the Mine of the future to collaborate on new technology such as Copper NuWave™, MicroHammer™ and WaveStream™.

Rio Tinto has also partnered with the Imperial College in London to investigate fundamental principles and develop efficient technologies for extracting and processing materials.

“We know we cannot rely on existing technologies and that we must innovate,” McGagh said. “We need new processes and approaches, and that requires new thinking – the kind of thinking that comes from internationally renowned centres of learning such as Imperial.”

Through new technologies and efficient framework, Rio Tinto is working to maximize its operational processes and increase productivity while lowering downtime.

Copper, iron ore surge as Chinese investors unleash demand

Iron ore broke $200 a tonne for the first time, while copper approached a record high as Chinese investors unleashed fresh demand following May holiday

The reopening of major industrial economies is sparking a surge across commodities markets from corn to lumber, with tin climbing above $30,000 a tonne for the first time since 2011 on Thursday.

In the wake of mounting evidence of inflation fuelled by higher raw materials prices, investors are also increasingly focused on when the U.S. Federal Reserve might start throttling back its emergency support.

Copper

Many banks say the rally has further to run, particularly for copper, which will benefit from rising investment in new energy sectors. Copper is at the highest in a decade, fueling bets it will rally further to take out the record set in February 2011. Steel demand is surging as economies chart a path back to growth just as the world’s biggest miners have been hampered by operational issues, tightening ore supply.

“The long-term prospects for metals prices are ‘too good’ and point to higher prices in the next few years,” said Commerzbank AG analyst Daniel Briesemann. “The decarbonization trends in many countries, which include switching to electric vehicles and expanding wind and solar power, are likely to generate additional demand for metals.”

Trading house Trafigura Group and several major Wall Street banks including Goldman Sachs Group Inc. and Bank of America Corp. expect copper to extend gains.

Copper rose as much as 1.6% to $10,108.50 a ton on the London Metal Exchange before trading at $10,080 as of 4:07 p.m. in London.

Iron Ore

Benchmark spot iron ore prices rose to a record, while futures in Singapore and China climbed.

The boom comes as China’s steelmakers keep output rates above 1 billion tons a year, despite a swath of production curbs aimed at reducing carbon emissions and reining in supply. Instead, those measures have boosted steel prices and profitability at mills, allowing them to better accommodate higher iron ore costs.

Spot iron ore with 62% content hit $201.15 a ton on Thursday, according to Mysteel. Futures in Singapore jumped as much as 5.1% to $196.40 a ton, the highest since contracts were launched in 2013. In Dalian, prices closed 8.8% higher.

Erik Hedborg, Principal Analyst, Steel at CRU Group commented: “Recent production cuts in Tangshan have boosted demand for higher-quality ore and prompted mills to build iron ore inventories as their margins are on the rise. Iron ore producers are enjoying exceptionally high margins as well, around two thirds of seaborne supply only require prices of $50 /dmt to break even.”

China

Still, some analysts including Commerzbank’s Briesemann expect a short-term correction as metals become detached from fundamentals. There’s also a risk that China could engage in policies that may cool demand for iron ore and copper.

The metals rally has boosted concerns about short-term Chinese demand. Some manufacturers and end-users have been slowing production or pushing back delivery times after costs surged, while weaker-than-expected domestic consumption has opened the arbitrage window for exports.

Tin climbed as much as 2% to $30,280 a ton on the LME, boosted by rising orders for the soldering metal. Tin is at the highest since May 2011, with a 48% gain this year making it the best performing metal on the LME.
