    EXPERIMENTAL AND STATISTICAL STUDY MUHAMMAD IMRAN .

    Experimental procedure Initially, the ore samples were dried, crushed and grinded up to the desired size. Niobium is a paramagnetic material, so its concentration in the ore was increased by processing the crushed ore in a magnetic separator. The resultant concentrate was screened into various fractions. Typically, about 8 g of

    The production process follows the exploration process. Drilling and blasting take place, and the ore is subsequently broken to be extracted. The underground mine is in operation 24 hours a day and 7 days a week. It extracts over million tons of ore which, once transformed, produces some 5000 tons of niobium annually.

    Niobium processing, preparation of niobium ore for use in various products.. Niobium (Nb) has a bodycentred cubic (bcc) crystal structure and a melting point of 2,468 °C (4,474 °F). Of the refractory metals, it has the lowest density and best workability; for this reason, niobiumbased alloys are often used in aerospace appliions.

    The valorization of pyrochlore ores is limited to niobium recovery through a pyrometallurgical route and is only applied to ores allowing an efficient ore dressing process. New pyrochlore ore deposits, especially in Gabon (Africa), contain very fine pyrochlore particles which cannot be efficiently enriched by ore dressing processes.
