Digitalisation and Automation
Key Takeaway
  • Hindustan Zinc is scaling digitalisation across mines and smelters.
  • Advanced technologies are delivering measurable outcomes in safety, reliability, process stability, and cost, while improving operational continuity.
  • Hindustan Zinc 2.0 priorities: Scale every flagship deployment across all sites, deepen AI integration, and build a solid foundation for scalable, tech-first operations.

Digital innovation is key to shaping the future of metals and mining. We are systematically embedding technologies like artificial intelligence (AI), automation, connected systems, and tele-remote technologies to build a smarter, safer, and more responsive enterprise. As we advance HZL 2.0, these advanced technologies and intelligence will enable us to operate a larger, more complex enterprise with the same precision, reliability, and cost-effectiveness.
