Major metallic ore deposits of Ethiopia consist of precious metals Au, Pt , rare metals Ta and to a lesser extent Ni and Fe; some deposits are currently mined for Au and Ta e.g. Lega Dembi, Kenticha or are at an advanced stage of investigation e.g. Bikilal project, Fe ; to date, base metals Zn, Pb, Cu and alloy metals Cr, Mo, Mn are ...

Adola in southern Ethiopia is the most exciting region for tantalum. It is known to host a long and linear belt of this rare metal occurrence of tantalum and niobium in its Kenticha Belt, which extends for over 100 kilometres and covers an area of more than 250 kilometres. Three types of ore have been identified in the deposit:
deposits in South Africa and Rhodesia and from podiform de posits in alpine peridotites in the Soviet Union. The Stillwater Complex, a stratiform complex in Montana, contains substan tial tonnages of chromite, but the ore has a low Cr2 03 content and is high in iron; if the United States& 39; industry were to be

chromite deposits are found in dunite or peridotite near the contact of the cumulate and tectonite zones in ophiolites. We have identified 1,124 individual podiform chromite deposits, based on a 100-meter spatial rule, and have compiled them in a database. Of these, 619 deposits have been used to create three
Ethiopia is indeed the land of plenty, with resources found in abundance throughout its huge and diverse land mass. Geological surveys conducted on minerals in Ethiopia, have shown formations that are believed to contain a vast amount of mineral resources, with proven deposits of industrial minerals, coal, precious metals and metals.
Magmatic Ore Deposits: A number of processes that occur during cooling and crystallization of magmatic bodies can lead to the separation and concentration of minerals. 1-Pegmatites 2-Layered intrusions 3-Kimberlites Examples of Magmatic ore deposits: 1-Chromite deposits 2-Nickel ŒCopper deposits 3-Platinum group metal PGM deposits
