Metallurgic Processes

The HIsarna steelmaking process is a process of primary steelmaking in which iron ore is processed almost directly into steel The process is based on a new type of blast furnace called a Cyclone Converter Furnace which makes it possible to skip the process of manufacturing pig iron pellets a necessary step in the basic oxygen steelmaking process Get price

Creating Iron

At this point the liquid iron typically flows through a channel and into a bed of sand Once it cools this metal is known as pig iron To create a ton of pig iron you start with 2 tons (1 8 metric tons) of ore 1 ton of coke (0 9 metric tons) and a half ton (0 45 metricGet price

Iron Range 101 What is taconite?

Taconite is a low-grade iron ore Originally thought to be of little value taconite was considered overburden (waste) in the days when high grade iron ore was mined The iron content magnetite is only 20- 30% compared to 50 - 60 % iron content in red ore Red ore is also referred to as direct shipped ore because it can be shipped without processing Get price
