HIsarna is a new alternative ironmaking process of ULCOS program, which is under intensive development at EU. It uses coal and fine iron ore directly as raw materials instead of coke and pellet. In this context, the melting and pre-reduction behaviour of hematite ore in the smelting cyclone of HIsarna process was studied in the laboratory scale.

May 21, 2010· Massive‐hard, flaky‐friable, blue dust and lateritic varieties of iron ores are the major ore types, associated with banded hematite, jasper and shales. These ores could have formed as a result of supergene enrichment through gradual but extensive removal of silica, alumina and phosphorus from banded iron formations and ferruginous shale.

A bentonite has been using as a binder to iron ore pelletization from very beginning. It gives excellent binding property to green and dry pellet properties. However several drawbacks of bentonite have been observed such as an impurity due to its
temperature than gas-hematite reduction. The smelting cyclone of the HIsarna process is a compli-cated high temperature reactor. In the smelting cyclone, the temperature is extremely high and the size of the iron ore particles is very small. The smelting cyclone provides a suit-able environment for the thermal decomposition of iron ore particles.
Jan 01, 2015· The reverse cationic flotation route widely used in the iron ore industry is less selective for alumina–hematite separation than for quartz–hematite separation. Pradip et al. (1993) studied the flotation of an alumina-rich Indian iron ore and reported that only 60% of the iron could be recovered in reducing the aluminum content from 11.6% ...
2.2 Smelting heat of iron ore Smelting heat HS is the heat consumption necessary for iron ore smelting. It is intensively infl uenced by the metallization degree R m of pre-reduced iron ore and can be calculated through heat balance. For R m =1, it is considered that the calcinations of limestone and dolomite is 100%. Let R m
