Iron Ore

Desku™ Group México S.A. de C.V., a subsidiary of Desku™ Group Inc., is a Mexican barite, copper and iron ore mining company.

 

Desku™ Mining Group's strategic partners are legally constituted companies incorporated in Mexico, with the purpose of exploitation and extraction of barium sulphate and iron ore minerals. Through the years Desku™ Group has developed and cultivated close relationships and working partnerships in the  Mexican mining industry.

Iron Ore Specifics and Types:

 

 

Most useful metal in the world, Iron, is extracted from iron ore. It is the rock from which metallic iron can be economically extracted. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). The iron ore, usually, very rich in iron oxides (Fe3O4 and Fe2O3). Iron ores are mostly dark grey to rusty red in color and high specific gravity.

 

Types of iron ore:  

Two main types of iron ore used for iron making – Magnetite (Fe3O4) and Hematite (Fe2O3). Common iron ores include: 

  

            Hematite - Fe2O3 - 70 percent iron 

            Magnetite - Fe3O4 - 72 percent iron 

            Limonite - Fe2O3 + H2O - 50 percent to 66 percent iron 

            Siderite - FeCO3 - 48 percent iron

 

Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. 

Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries. The seven largest of these producing countries account for about three-quarters of total world production. Australia and Brazil together dominate the world's iron ore exports, each having about one-third of total exports.

 

Grades of Iron Ore:

Iron ore is typically classified as High grade (+65% Fe), Medium grade (+62 – 65% Fe) and Low grade (-62% Fe). Typically, the Integrated Steel Plants(ISPs) use medium/High grade Iron Ore whereas the Sponge Iron plants require only High Grade iron ore, preferably, with +67% Fe.

 

(i) Lumpy/Fine Ore: Iron Ore is traded in lumps (i.e. sized ore) or in fines. Production/availability of lumps is limited by virtue of the natural occurrence and also because of generation of lot of fines during crushing of large lumps present in the run-of –mines (ROM).

 

(ii) Natural Pellet: It is a term coined by producers in some Asian counties, to designate sized iron ore used directly in Sponge Iron production. 

 

(iii) Blue Dust: Blue Dust is the name given to naturally occurring, extremely friable, high grade Hematite Iron Ore powder.
