Composition Of Trace Elements In Blast Furnace Slag

Nov 22 2018018332The roasting losses may not exceed 6 if the furnace slag is used as the only additive for the production of aggregates the furnace slag aggregate may be used in construction industry after treatment Smarzewski and BarnatHunek 2015 In slags there occur trace elements which constitute from 01 to 03 of the total weight of the waste

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
