ENRICHMENT OF MAGAMI FERRUGINOUS MANGANESE DEPOSIT, ZAMFARA STATE, NORTH-WESTERN NIGERIA
Publication Date : 22/05/2020
This work was carried out to enrich Magami ferruginous manganese deposit via sample collection, sample preparation, chemical and particle size analyses, and beneficiation tests. The collected materials from the site were prepared in the laboratory to obtain a representative sample. The elemental composition of the ore revelation of 13.1% Mn showed that the manganese deposit is by and large of low marketable grade in accordance with the International Manganese Institute classification (<30%Mn). The optimised beneficiation test conducted using 125 µm particles size with shaking table yielded an assay value of 38.71% Mn. Therefore, the concentrate is typically suitable for either manganese alloy or manganese pig-iron production by direct smelting.
