Main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux (limestone) fines. In addition to base mix, coke fines, flux fines, sinter fines, iron dust (collected from plant de-dusting system & ESP) and plant waste are mixed in proportion (by weight) in a rotary drum, often called mixing and nodulizing drum.
Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.
The plant operating results for this flow sheet showed that an iron ore concentrate containing 52.0% Fe could be produced from a run-of-mine ore containing 40.4% Fe, at a mass yield to the iron concentrate of 57.5%, an iron recovery of 74.1%, and a tailings grade of 24.6% Fe.

Due to the high tonnage for the iron ore cyclone plant a modest increase in plant efficiency such as 1.5% yield increase would have a large impact on plant
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.

HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.
Iron processing Iron processing Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine.
With its completion, Northshore Mining is now the only U.S. based iron ore processing facility to produce low silica DR-grade pellets. The Northshore operation is producing DR-grade pellet feedstock inventory for Cliffs’ Hot Briquetted Iron Plant in Toledo, OH, which will be commissioned in mid-2020.

We can fix issues in ways you never thought possible. Our fresh eyes will open new opportunities for your plant. Each mineral processing plant is different: with varied ore types, mining equipment, and management (operating) philosophy. The evaluation and prioritisation of variables that affect the plant performance is the primary function.
