Production of High-Carbon Ferromanganese in Blast
14/11/2013· Some deleterious components can be partially removed from the ore prior to melting by dense-medium separation or flotation. Slaging components (dolomite or limestone) can be added to the sintered or pelletized ore, which result in cost savings in the blast furnace. Partial reduction of the higher manganese oxides may also occur during sintering.
Blast furnace Wikipedia
Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide to elemental iron mixed with carbon. The blast furnace operates as a countercurrent exchange process whereas a bloomery does

Chemistry of the Ironmaking by Blast Furnace Process
Reduction of Sulphur. Sulphur enters the blast furnace mainly in coke and is released into the blast furnace gas stream either as H2S or a gaseous compound of carbon monoxide and sulphur (COS) when the coke is burned. As the gas ascends through the stack some of the sulphur combines with the lime in the flux and some combines with the iron. The
Usability of Blast Furnace Flue Dust in Solid-State
A study was performed on solid-state reduction of manganese ore concentrate, which contained 50.23% manganese and 0.32% iron, by using coke dust and blast furnace flue dust towards ferromanganese production. The obtained results revealed that blast furnace flue dust was more convenient for the process than mill scale dust. As an initial solid-state reduction treatment, manganese ore

Blast Furnace Charge (Raw Materials for
11/01/2013· 1. QUALITY OF CHARGE MATERIAL: A blast furnace charge consists of coke, ore or sinter, and limestone. These materials must be in lumps of a certain size (40-60 mm). Larger lumps prolong the process of reduction and fluxing. Smaller lumps block the flue-gas passages and prevent a uniform descent of melting materials in the furnace. 2. IRON ORES: Ore is a metal bearing mineral.

Reduction of Zinc Oxide in Manganese Furnace Dust with Tar
The manganese furnace dust contains high concentration of manganese oxide. Recycling of manganese furnace dust back into the ferroalloy furnaces would not only reduce an environmental liability caused by its storage, but also de-crease manganese ore consumption by utilising the man-ganese oxide content of the furnace dust. However, man-

What are manganese ore fines and how are they sintered?
18/12/2017· Once the fines are sintered, they then go to a blast furnace or an electric arc furnace, to smelt the manganese iron into manganese alloys. It is here that fines would be a big risk for literally gumming up the works or even causing explosions. In the blast furnace, hot gases are produced by the reduction reactions.
