Nigeria include heavy grazing of pastures activities of herdsmen smallholder farming and rural settlement Therefore it is crucial to estimate the diversity of plants affected by tantalite mining ac tivities Hence this study was designed to evaluate the floristic diversity in tantalite mining sites of the Nasarawa state Nigeria
The metallic minerals produced are mainly lead zinc manganese gold tin and columbite tantalite which are exported and forming about of total exports This paper examines the types of ore deposits in Nigeria Ores of iron tin niobium tantalum deposits and precious metals in the Nigerian basement complex are predominantly associated
Ore deposits are sources of raw materials for industries This paper examines the types of ore deposits in Nigeria Ores of iron tin niobium tantalum deposits and precious metals in the Nigerian basement complex are predominantly associated
This study investigates the lithochemistry of tantalite mineral from granitic pegmatite deposits in the Okpella area Northern Edo State Nigeria Tantalite a valuable mineral containing tantalum
Occurrence Of Columbite In Nigeria Columbite occurs in Plateau state Jos Nigeria mainly in the placers deposits of cassiterite usually found only a few of 10km from the granitic parent rocks It occurs as an accessory mineral in the northern parts of the country in smaller quantities but the richest deposits occur on the Plateau
The Gidan Jaja iron ore deposit is located in Zurmi Local Government Area of Zamfara State It is about 50km from Kauran Namoda Rail line and 100km from Katsina Airport The deposit is bounded by Latitudes 120 45 and 130 00N and longitudes 60 45 and 70 00 E and its preliminary estimated deposit is over 50 million tonnes [11]
Iron ore deposits found in abundance in Nigeria West Africa with up to 3 billion tonnes are in Nigerian states like Kaduna Enugu Kogi Niger Kwara Bauchi and Zamfara Iron ore is an essential rock mineral which formation came as a result of combined chemical reactions of oxygen and iron in marine and Iron ore mineral deposit in Nigeria
chemical leaching of a Nigerian tantalite ore The dissolution kinetics of the ore is also evaluated No reported works vis vis leaching a Nigerian tantalite ore with nitric acid is available This work is inscribed within the programme being undertaken on the dissolution kinetics of tantalum in different aqueous media [8] EXPERIMENTAL
Introduction Tantalite and other solid mineral deposits in Oke Ogun occupy a very large landscape and the possibilities of further exploration in new landscape and abandoning unproductive sites
