  • Automating and Optimizing Copper Heap Leaching Processes

    Jim Cahill
    Our world is dependent on all the copper wire distributing electricity and communications signals over great distances and throughout our homes and businesses. Mining and refining this copper into the purity required poses safety, efficiency and reliability challenges for global miners. I learned quite a bit about the mining process and its challenges from Emerson’s Alena Johnson excellent Mining Engineering magazine…

  • Quantifying the Resource Efficiency of the Global Steel Sector: Why is Our Metric Better?

    Jim Cahill
    Author: Ana Gonzalez Hernandez In my last post , I introduced Emerson’s new resource efficiency approach. With it, Emerson proposes a new way of thinking about resource efficiency. One that encapsulates many aspects of modern industry solutions: we leverage the value residing in available metered data, communicate key knowledge through powerful digital visuals, and do so by tracking more a holistic metric – be it…

  • Isolation Knife Gate Valve for Medium-Slurry Mining and Minerals Applications

    Jim Cahill
    Many manufacturing processes have challenging fluids flowing through their pipes and vessels. Mining and minerals have some of the most challenging with abrasive and corrosive solids in the flowing fluids. In a Valve magazine article, Challenges of Medium Density Slurry Service in Mining and Mineral Processing , Emerson’s Mike Gordon describes innovations in knife gate valve technology to address these slurries. …

  • China Sneezed and the Mining Industry Caught Pneumonia

    Jim Cahill
    Author: Alan Novak As noted in a recent Financial Post article , the world’s largest mining companies have fallen on hard times. Since 2011, global mining stocks have lost $1.4 trillion in value; more than the value of Apple, Exxon Mobil and Google combined. A few charts of the underlying commodities and related company stocks show just how bad it has been. Global copper price: Source: InfoMine – 5 Year Copper…

  • Improved Mining Safety and Operational Performance through Solids Level Measurement

    Jim Cahill
    Some industries, such as the mining industry, face the challenge of having to measure the level of solids. Unlike liquids, they must content with the peaks and valleys depending on the consistency of the solids being measured. Emerson’s Asael Sharabi shared a story with me about a Canadian copper miner. In their mining process, they crush five different types of ore. The raw ore is passed through a crusher and the…

  • “The 33” Movie Reminds Us of the Importance of Safety in Mining Operations

    Jim Cahill
    Author: Juan Carlos Bravo This weekend, the movie named “The 33” opened in theaters. It depicts the story of the 33 miners trapped for 69 days in a gold mine in Copiapo, in Chile. I think this movie provides a glimpse of how the mining operations are a serious but sometimes dangerous business. For manufacturers and producers across all the process industries, we know that safety can never be taken lightly or…

    Author: Juan Carlos Bravo In the past, we discussed how the metals and mining industry was increasingly becoming a target for cyber-attacks. An Ernst and Young report, Business risks facing mining and metals 2015–2016 recently upgraded cybersecurity into its top 10 business risks—up two spots to number nine. In this report, a 2014 Global Information Security Survey indicated that 65% of mining and metals companies…
