TORONTO, May 11 (Reuters) - Union workers at ArcelorMittal's ISPA.AS Mont-Wright iron ore mine in northern Quebec have ratified a new four-year contract with the steelmaker, the world's largest, the United Steelworkers union said on Thursday.
The 2,000 members voted on a contract that maintains the pension plan for all employees and provides pay parity for workers at the company's smaller, nearby Fire Lake mine, the union said.
Last week, the union gave a 72-hour strike notice after rejecting the company's offer over concerns about wages, pensions, sub-contracting and pay disparity. workers operate the large open pit Mont-Wright mine in Quebec, a railroad link to port, a processing plant in Port Cartier and Fire Lake mine.
Last year, Mont-Wright produced some 27 million tonnes of iron ore at a cash production cost of $25 per tonne.
In 2013, ArcelorMittal sold a 15 percent stake in Mont-Wright to South Korean steelmaker Posco 005490.KS and Taiwan-listed China Steel Corp 2002.TW for $1.1 billion.
