An investigation is underway into an industrial accident at a zinc smelting plant in Beaver County that killed 2 men and injured 2 other workers. The coroner has not released the identity of the men who died. Workers at the Horsehead zinc plant reported hearing what they described as explosions although the company is not calling the accident an explosion. The accident occurred in the zinc distillation columns...part of the facility's zinc oxide refinery. That's where the molten zinc is converted to zinc oxide.
The company employs 600 at the plant which according to the firm's website is the largest zinc smelting operation in the nation.
