Beneficiation process for sorting monazite through classification jigger

The invention provides a beneficiation process for sorting monazite through a classification jigger. The process comprises the following steps of that (1) a monazite rough concentrate raw material is selected and then is screened into products with three particle sizes, namely + 0.2 mm products, -0.2 + 0.074 mm products and -0.074 mm products by using a high-frequency vibrating screen; (2) the-0.2 + 0.074 mm products are jigged to obtain jigging concentrate 1 and tailings 1, and the-0.074 mm products are jigged to obtain jigging concentrate 2 and tailings 2; (3) the tailings 1 obtained in the step (2) and the + 0.2 mm products are mixed and stirred, and large jigging is carried out again to obtain jigging concentrate 3 and tailings 3; and (4) the jigging concentrate 1, the jigging concentrate 2 and the jigging concentrate 3 are combined to obtain the monazite concentrate. The beneficiation process effectively increases the grade and comprehensive recovery rate of monazite ore. 本发明提供一种分级跳汰机分选独居石选矿工艺，包括以下步骤：(1)
