REDCAR, ENGLAND - APRIL 18:  Slag is tapped off the furnace at the SSI iron furnace after making its first steel slab in two years on April 18, 2012 in Redcar, England. The former Corus owned furnace was mothballed two years ago but was bought by Thai firm Sahaviriya Steel Industries (SSI) who have given jobs back to many of the 1,600 workers who lost their jobs.
