Abstract

The invention discloses a method for flotation separation of tantalum-niobium and spodumene from spodumene concentrate containing tantalum-niobium. The method for flotation separation of tantalum-niobium and spodumene from spodumene concentrate containing tantalum-niobium comprises the following steps that a pH regulator is added into concentrate ore pulp or dry concentrate containing tantalum-niobium iron ore or tantalum-niobium manganese ore and spodumene, the ore pulp is kept under an alkaline condition, then a spodumene inhibitor is added, a tantalum-niobium ore activator, a tantalum-niobium collector and a foaming agent are added, and rough separation is carried out to obtain tantalum-niobium rough concentrate and tantalum-niobium rough tailings; the tantalum-niobium collector and thefoaming agent are added into the obtained tantalum-niobium rough tailings to perform scavenging for two to three times to obtain scavenging concentrate, and the scavenging concentrate is sequentiallyreturned to an previous stage of operation; the spodumene inhibitor is added into the obtained tantalum-niobium rough concentrate, two to four times of concentration is carried out, the concentratedmiddlings is sequentially returned to the previous stage of operation, and a final foam product is the tantalum-niobium concentrate. The method for flotation separation of tantalum-niobium and spodumene from spodumene concentrate containing tantalum-niobium can effectively enrich tantalum-niobium ores and realize the separation of tantalum-niobium ores and spodumene.

Description

technical field [0001] The invention belongs to the technical field of ore dressing, and in particular relates to a method for separating tantalum, niobium and spodumene by flotation of spodumene concentrate containing tantalum and niobium. Background technique [0002] Worldwide, spodumene resources at home and abroad are mostly located in granite pegmatite or basalt veins, which are generally associated with tantalum-niobite or tantalum-niobium-manganese ore, and flotation, as the mainstream beneficiation process of spodumene, will tantalum Niobium is enriched in spodumene concentrate. Conventional spodumene concentrate recovery of tantalum-niobite or tantalum-niobium-manganese ore utilizes the specific gravity difference between tantalum-niobite or tantalum-niobium-manganese ore and spodumene, and recovery through shaking table is mainly based on gravity separation. lower. [0003] Chinese patent CN 102861662 A discloses a beneficiation method of tantalum-niobium ore, w...
