    D Zhu, in Iron Ore, 2015 16311 Background In a DR process, iron ore pellets and/or lump iron ores are reduced by a reducing gas to produce DRI or hot briquetted iron (HBI) Depending on the generation of the reducing gas, two different DR processes are commercially available: gas   •DR pellets: >50 % + 125 mm vs • BF: 95 x 125 mm target • Benefits of larger pellets : Increase in permeability, increased yield ( fewer smaller pellets degrading into fines), reduced clustering tendency (with a decrease in contacting surface area) • Drawbacks of larger pellets : Decreased reduction heat transfer efficiencyIron Ore Pellets: North America, BF and DR Grade, Supply Blast furnace pellets made up 55% of sales value and DR pellets accounted for 26% According to iron ore trade statistics, Sweden exported about 7 million tons of DR pellets in 2017, compared with 65 million tons in 2016 The breakdown of exports by country in 2017 is shown in Figure 5 The installed pellet capacity of LKAB is about 28 million t/y, with three lines at Kiruna (BF and DR pellets), two at Malmberget (BF pellets) and one at Svappavaara (BF pellets)DRGrade Iron Ore Pellets A Supply Overview
