Lead processing - Lead processing - Mining and concentrating: Once the ore is removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills. Here the ore is finely crushed, sometimes to particle diameters of less than 0.1 millimetre (0.004 inch), and then treated by one of several mineral

Oct 01, 2013 The induration process using traveling grate can be divided into 4 different stages: drying, heating, firing and cooling zones [1]. The first step ensures that the pellets are fully dried with controlled velocity in order to keep the integrity of the pellets and forms the initial bonding phases.

Jan 01, 2012 In Grate-Kiln process, green pellets are fed on oil or gas-fired endless Straight Grate machine where they are dried and preheated. The preheated pellets are then fed to a rotary kiln where their temperature is raised in oxidizing atmosphere to 1290–1400 C. In induration, ore grains are sintered together with oxidation and slag-forming bonds.

The fire pellets are removed from the grate by a scraping device which is installed at a sufficient distance between grate bar and hearth layer (with a depth approximately 5 cm) to leave the hearth layer in its position. The other route to preparing iron ore fines is to agglomerate them

Mar 09, 2013 The sintering process is used to agglomerate a mix of iron ores (blend), return fines, fluxes and coke, with a particle size of less than 10 mm, so that the resulting sinter, with a screened size of 10 mm to 30 mm, can withstand pressure and temperature

Dec 20, 2017 Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration

Investigation of the layering mechanism of agglomerate

Feb 19, 2003 Pelletization has extended the life of the iron ore industry by enabling the treatment of low-grade iron ores, which are available in large reserves throughout the world. Iron ore pelletization is a two-step process consisting of pellet production in balling circuits and pellet induration in straight-grate or grate-kiln systems.
