Russia: NLMK Group has signed a five-year contract for the supply of raw materials, including granulated slag, to Eurocement group. The contract, which runs until the end of 2022, covers an annual supply of up to 5Mt of raw materials for use as primary feedstock and additives for cement production at seven Eurocement plants.
Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina.
List of countries by steel production. This is a list of countries by steel production in 1967, 1980, 1990, 2000 and from 2007 to 2019, based on data provided by the World Steel Association. All countries with annual production of crude steel at least 2 million metric tons are listed.

Sources and Production of Slag Iron, steel, and copper are three important engineering materials. Iron is mostly extracted from oxide deposits, while copper is obtained from polysulfuric ores or porphyry intrusions . Almost 98% of iron ore is used for production of iron and
The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel.
As a result, a vast quantity of slag is generated in ferronickel production, which is a significant concern for ferronickel plants worldwide. For every tonne of ferronickel alloy produced, 4 tonnes of slag are generated, 31 and the annual ferronickel slag production in Greece alone was about 1.7 Mt in 2007.
