Nyrstar

Nyrstar is a Belgian-domiciled multi-metals producer that focuses on the extraction, refining, and marketing of zinc, lead, and precious metals. The company supplies these metals to a range of downstream industries, including construction, automotive, electronics, and industrial manufacturing. Its operations encompass mining activities, smelting, and refining processes that transform raw ore into high-purity metal products. Nyrstar serves customers across Europe, North America, and Asia, providing metal alloys and specialty products that meet specific performance requirements. The firm also offers recycling services for metal-bearing residues, contributing to circular economy initiatives. Its product portfolio includes galvanizing zinc, die-casting alloys, and silver‑gold concentrates used in various high‑tech applications.

In January 2019, Nyrstar experienced a cyberattack that targeted its IT infrastructure, leading to the temporary shutdown of email and other internal systems to contain the breach. The company confirmed that its metals processing and mining facilities continued to operate without damage during the incident. Response efforts involved close coordination with external IT partners and international cybersecurity agencies to develop and execute a technical restoration plan. This episode highlighted Nyrstar’s reliance on secure digital systems for operational management and its capacity to engage specialised external expertise under crisis conditions. The incident also underscored the growing cyber risk faced by industrial enterprises with extensive automation and data‑driven processes.

Nyrstar distinguishes itself as one of the world’s largest producers of zinc, a metal essential for galvanisation and corrosion protection. Its integrated value chain combines mining concessions with smelting and refining assets, allowing it to control quality from ore to final product. The company maintains a strong focus on sustainability, investing in energy‑efficient technologies and low‑carbon initiatives across its sites. Nyrstar’s technical expertise in metallurgy and process optimisation enables it to produce specialised alloys that meet stringent industry specifications. Its global footprint includes smelters in Europe, the United States, and Asia, as well as mining operations in Australia and South America, providing geographic diversification of supply. The firm’s market position is reinforced by long‑term supply contracts with major industrial consumers and its participation in commodity exchanges that influence zinc pricing.
