Activities involved in finding, mining and processing iron ore at our Pilbara operations have been simplified in the following diagram. Rio Tinto operates 11 iron ore mines in the Pilbara and the specific sequence of activities varies from mine to mine. Excellence in planning, scheduling and quality control are fundamental to the process.
WhatsApp: +86 18838072829Iron ore pellets are largely characterized by inherent physical and chemical properties of the ore. Alumina and silica play important roles in determining the productivity of a Blast Furnace. On average, one percent increase in iron content improves productivity by 2% and reduces coke consumption by 1%. Therefore higher iron ore feed content to blast furnace is always preferred. Indian ...

WhatsApp: +86 18838072829The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from Mta capacity to 28 Mta in the forthcoming years.
WhatsApp: +86 18838072829Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.

WhatsApp: +86 18838072829Cliff's Tilden plant in Cleveland, USA, is the only iron ore beneficiation plant, where selective flocculation technique, using degraded starch as the flocculant, has been applied to produce pellet grade concentrate from a feed containing around 32% Fe . The plant has a capacity of processing 10 million tons and is in operation since 1975.
WhatsApp: +86 18838072829DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
