Slag is one of the most valuable secondary material resources. Blast furnace slag is used for making granulated slag (over 50%), road stones (17%), pumice (3%), slag wool of molten metal; high-aluminous clinkers and cast wares are manufactured on a small scale. Blast-furnace slag grinding line and blast-furnace slag drying line are used for produsing blast furnace slag.

Large areas of fertile lands are used for keeping and storing these disposals, much money goes to slag maintenance and transportation from the blast furnaces to disposals, environment is contaminated.
