Blast Furnace: Equipment used for the production of iron in the form of pig iron from iron oxides by the use of coke and/or charcoal as a reducing agent, generating liquid and/or solid pig iron as sub-product is also liquid and/or granulated.

Blast Furnace Lump Ore: Iron ore with particle size between 6.35 mm and 50.0 mm in diameter, with suitable chemical and metallurgical characteristics to be loaded directly into the blast furnace.


C
 
Cape Size Vessel: A vessel suitable for the transport of solid bulk cargoes with a capacity of transport between 120,000 tons and 180,000 tons of net cargo.

Concentration: Industrial process based on physical, chemical or biological treatments to increase the content of the element of interest of the desired mineral.

Coke: Product obtained through an industrial process that promotes the transformation of coking coal into coke.

Coke or Coking Coal: Bituminous coal of a quality that allows the production of coke suitable for supporting a blast furnace charge. Usually used in coke ovens for metallurgical purposes such as the production of pig iron.

Charcoal: Substance obtained by the carbonization of wood, firewood or forest residue.
D

Direct Reduction: A process that removes oxygen from the iron ore without melting.

Directly Reduced Iron: Iron ore, granulated or pellets, converted by the Direct Reduction process, used mainly as a substitute for scrap in the steelmaking in an electric furnace.
 
E

Encumbrance: An act that prevents the negotiation of certain property, next to the Land Registry, avoiding that it can be sold or alienated.
 
F

Ferro-Alloy:Iron alloys that contain one or more chemical elements. Used to add these other elements to the molten metal, usually in steelmaking. The main ferro-alloys are chromium, manganese and silicon.

Fine: Iron ore with particles smaller than 6.35 mm in diameter and greater than 0.15 mm. They are suitable for sintering. When less than 0.074 mm are suitable for pelletizing (see Ultra-fines).
 
H
 
Hot Briquetted Iron:Briquetted Sponge Iron. Iron-sponge that was processed in briquettes.

 
 
 
I
 
Inferred Mineral Resource: it is a part of the mineral resource in which the quantity, degree or quality, density, shape and physical characteristics can be estimated by geological evidence, limited and reasonably accepted samples, but not being verified the geological continuity and the degree.

Indicated Mineral Resources: it is a part of the mineral resource in which the quantity, grade or quality, density, shape and physical characteristics can be estimated with a level of precision sufficient to allow the application of the technique and appropriate economic parameters, in order of basing the mining plan and assessing the economic viability of the deposit.

Iron Units:Measure the iron content in iron ore which is equivalent to 1% of the iron content in one ton of iron ore.

 

L

Long Ton:
Unit of mass measurement, equivalent to 1,065,05 kilograms.


 
M

Mineral Reserve: Mineral Reserve is subdivided to increase certainty in Probable Reserves and Proven Reserves. Probable Reserves are less certain than Proven Reserves.

Mining Right: Mining concession, which has, by title, an ordinance signed by the DNPM, which allows the industrial exploitation of the deposit, from the extraction of the useful mineral substances it contains, until its processing.
 

P

 
Panamax Vessel: A vessel suitable for the transport of solid bulk cargoes with a capacity of transport between 50,000 tons and 75,000 tons of net cargo.

Pellets: A product formed by ultra fine, agglomerated iron ore particles of between 8mm and 18mm in size and suitable for the process of reducing the iron oxides in iron (pig iron or sponge iron).

Pellet Feed: Fine ore for pelletizing.

Probable Mineral Reserve: is the economical mineral part of the Indicated Resource, and in some circumstances the Measured Resource demonstrated by at least one preliminary feasibility study. This study should include correct information on mining, processing, metallurgy, economics, and other relevant factors that demonstrate and justify economic extraction at the time of the report.

Processing: Process of crushing, concentrating and classifying minerals through physical and chemical processes in order to obtain the ore or mineral in the desired quality. Proven Mineral Reserve: is the mineral economic part of the Measured Mineral Reserve demonstrated in the preliminary feasibility study. This study should include correct information on mining, processing, metallurgy, economics, and other relevant factors that demonstrate and justify economic extraction at the time of the report.

Pig iron: Product obtained in blast furnace based on coke or charcoal.
 
R
 
Real Guarantee:The one made up of lien on certain property owned by the debtor.

 
S

Sinter Feed: Mineral fines for sintering.

Sintering: Agglomeration of iron ore particles through the burning of coal fines.



 
 
T

Thermal Coal: Type of coal suitable for the generation of energy after its vaporization properties. Used in thermal power stations.

Tonnage: Unit of mass measurement, equivalent to 1,000 kilograms.

TKU: Net tonnes per useful kilometer, i.e. the weight of the goods transported excluding the weight of the wagon.

 
U

Ultra-Fine: Ultra-fine iron ore particles, less than 0.074 mm, generated by mining, processing and handling.

 
 
 
 
 
V
 
VLOC Vessel: A vessel suitable for the transport of solid bulk cargoes with a carrying capacity above 300,000 tons of net cargo.
