The post-WWII boom in the iron ore demand pushed the producers to steeply increase the productivity in an overall old-fashioned and labor intensive industry. During the 1950's, introduction of modern concentration plants phased out traditional lump ore in favor of pulverized concentrate, known as "slig".
