MINERALOGICAL CHARACTERIZATION OF THE GOLD-BEARING

Gold production in Nigeria is believed to have started in 1913 and got to its peak from 1933-1943 (MMSD, 2010). Gold in the schist belt of Nigeria occur as alluvial and elluvial deposits. Only 5-10% of Nigeria‟s 12,000kg of reported gold production has come from vein deposits, while the greater part has been from modern alluvial derived from basement rocks. Four gold fields, encompassing the ...
