The invention provides a comprehensive recycling process for associated tantalum-niobium ores. Mainly, classification is conducted after raw ores are rough ground; rough grain tantalum-niobium minerals and mica minerals rich in rare metal are recycled from rough grain products on a sieve through a high-gradient magnetic separation-heavy fluid separation method; fine fraction tantalum-niobium minerals and feldspar minerals rich in rare metal are recycled through a floatation method after sulphide ore floatation and impurity removal are conducted on products below the sieve; a combined collecting agent which includes diphosphonic acid, benzohydroxamic acid and soybean oil acid flotation and is high in tantalum-niobium mineral selectivity and collecting capacity is added during tantalum-niobium flotation so that tantalum and niobium can be obtained through floatation. By means of the process, tantalum-niobium minerals good in index are obtained, and other associated rare metal in the minerals is comprehensively recycled.
