FINEX Process is a fluidized bed based process using ore fines instead using iron ore lumps and pellets. This is a process with great potential with regard to productivity and the low cost production of hot metal. In 1992, POSCO and VAI, Austria signed an agreement to work together for a joint development of the FINEX Process.

L.S. Nikolaisen, P.D. Jensen, in Biomass Combustion Science, Technology and Engineering, 2013. Densification by briquetting. Briquetting is – like pelletising – a process in which the raw material is compressed under high pressure, which causes the lignin in the wood or biomass to be liberated so that it binds the material into a firm briquette.. The most appropriate water content in the ...

Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).

The fines can be either simple DRI fines which have been completely misdescribed by the shipper, or fines produced during production of HBI. If the fines have been produced after the HBI briquetting process then it is possible that they may be in a relatively safe form and could be treated in a similar manner to HBI briquettes.
