Greater Sudbury Police say they're working in collaboration with the Ministry of Labour to investigate an industrial accident at Sudbury Integrated Nickel Operations, A Glencore Company in Falconbridge, a suburb of Sudbury, on May 9.
Police say they received a call about the accident at around 9 p.m. A 56-year-old man was transported to hospital in critical condition and a 55-year-old man and 46-year-old man were treated by paramedics for non-life-threatening injuries.
It was reported that a worker came in contact with a substance causing the injuries.
"A ministry inspector attended the scene. No orders were issued and our investigation is ongoing," said MOL spokesperson Janet Deline.
The Ministry of Labour is taking the lead in the investigation, say police.
Sudbury Integrated Nickel Operations operates the Nickel Rim South Mine, Fraser Mine, the Strathcona Mill, and the Sudbury Smelter.
Nickel and copper are the primary metals produced, but the company also produces cobalt and precious metals such as gold, silver, platinum and palladium.
The Strathcona Mill receives ore from the two Sudbury mines as well as third-party custom feed ores. It produces two concentrate streams: nickel-copper concentrate for smelting, and copper concentrate for smelting and refining.
The Sudbury Smelter currently smelts nickel-copper concentrate and processes custom-feed materials in the form of concentrates and secondary products. These products go by rail to port facilities in Québec City, and from there to our Nikkelverk refinery in Norway.
