Iron Ore

The deposition of iron in Yemen is related to the intercalated marble beds in the meta-andesites or the intrusion of the diorites. Each individual iron mineralization zone generally ranges in length from ******0 m, and may attain up to **0 m at most; the length of each individual ore body is generally *****0 m, with a maximum of **2 m ; the thickness of the ore bodies is generally **5 m, reaching a maximum of *0.*4 m ; the total iron content generally ranges from ****5%, with a maximum of *7.*0%, and the great majority of the contents of sulphur and phosphorus are below 0.1%. So the iron deposits and occurrences are of the low-impurity, small and rich type. The ore consists mainly of magnetite, partly with martite and small quantities of siderite and limonite..

 

The iron mineralization occurs in Yemen in a number of sites within four major belts; Al-Beidha, Sa'ada, Marib along with Al-Thanyia area which is one of the most important ferrite sites in Yemen.
