Iron Ore Pellet Dustiness Part II: Effects of Firing Route

Iron ore pellets abrade during their production and handling, which lowers product quality and leads to dustiness issues. Pellets were collected from a variety of plants (operating either Straight-Grate (SG) or Grate-Kiln (GK) furnaces) to understand whether furnace type affects fines and dust formation.

Blue dust home page

Blue Dust: Noun /Blu Dʌst/ 1. Generic term commonly used when the iron ore is dominated by very fine, soft hematite. As hematite grains often have a steely blue-grey colour, the soft powdery ore is nicknamed "blue dust". He was working at the steel mill today and came home covered in blue dust. 2.

The Sintering Process of Iron Ore Fines IspatGuru

Mar 09, 2013· The process of sintering begins with the preparation of the raw materials consisting of iron ore fines, fluxes, in-plant metallurgical waste materials, fuel and return fines of the sinter plant. These materials are mixed in a rotating pelletizing drum and water is added in order to reach proper agglomeration of the raw materials mix.

Siderosis (Iron Dust Inhalation) Lung Disease

Siderosis, also called welder's lung, is a lung disease caused by breathing in iron or iron oxide dust. Siderosis is considered to be an occupational illness because people breathe in the iron dust at work. The condition usually shows up on X-rays as small, opaque spots on the worker's lungs.

Iron ore Wikipedia

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and
