Understanding the high-grade iron ore market

iron ore market. Suppliers of the highest-purity beneficiated ores will generally target DRI producers as their preferred customers given the attraction of the 'DR-grade premium'. The economic wisdom in spending money to upgrade iron ores to such high purities diminishes if the customer is a blast furnace

Iron Ore,Production Process of Iron Ore,Iron Ore ...

Iron ore is an important raw material for iron and steel production enterprises. After crushing, grinding, magnetic separation, gravity concentration etc, gradually we can get iron from natural minerals (iron ore). It is the mineral aggregates that contain iron or iron compounds which can be used economically. Production Process of Iron Ore ...

Beneficiation of Iron Ore - Mineral Processing & Metallurgy

Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500 ...
