Sinter ore iron-ore fines is produced by crushing, screening and deslurrying high-grade ore rich in iron, fineness being less than 10 mm. Direct-shipping ore lumpy ore is also produced from high-grade ore, fineness being minus 70 and plus 10 mm. Iron-ore raw materials for a blast-furnace process are usually sintered or pelletized.

locally available raw materials for the production of refractory bricks . The basic raw material was kaolinitic clay from Dewechla deposit it was possible to produce Chamotte refractory bricks with the initial softening point of 1180Co. Olokode et al,2012 investigated the suitability of using clay
The raw materials needed for the production of pig-iron are iron ore and coke. Depending on the type of impurities in the iron different fluxes are added, for example limestone for siliceous iron ore or feldspar for calcareous iron ore. The flux converts the impurities in the iron to easily meltable slag.
Nov 23, 2018 A rational clay moisture content is determined for briquetting in a roller press 21. It is established that briquette preparation with this moisture content makes it possible to minimize briquette breakage during heat treatment and energy expended in material drying before compaction, and also to increase the yield of finished briquettes ...

2 Materials Used to make Steel 2.1 Iron Ore Composition Iron very rarely occurs in the earths surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5 by weight of the earths crust. Geologists recognise various types of iron ore, classified chiefly according to iron Fe
Fullers earth is used mostly as an absorbent material 74, but also for pesticides and pesticide-related products 6. Kaolinite is a clay composed of the mineral kaolin. It is an essential ingredient in the production of high quality paper and some refractory porcelains.
Bentonite production and resource. The Bentonite raw materials we use to produce our different grades of powdered products are all sourced from recognised deposits of both Mediterranean and USA origins. These specific sources are well known and are proven to be of the highest quality and consistency.

Iron ore is the principal metallic ore of East Texas, with reserves of mineable ore estimated at 200 million tons. These ores are used as raw materials for steel making, as mineral fillers and additives, and as portland cement additives.
Blister steel used by Huntsman as raw material was made by the cementation process or by carburization of iron. Carburization is a heat treatment process, in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder.
