Abstract

The invention provides a beneficiation method for a seashore sea beach placer. The beneficiation method comprises the following steps that a shore sand ore raw ore meeting a preset particle size rangeis put into a flotation cell, water is injected into the flotation cell for size mixing so as to obtain ore pulp with preset ore pulp concentration; floatation is carried out on the ore pulp with thepreset ore pulp concentration, 240 g/t to 260 g/t of sodium carbonate, 120 g/t to 130 g/t of caustic soda and 1250 g/t to 1500 g/t of water glass are added into the ore pulp, and stirring is carriedout according to a first preset time; when stirring is carried out at the first preset time, oleic acid is added; when the oleic acid is added and the stirring is carried out according to a second preset time, 120g/t to 130g/t of a target foaming agent is added into the flotation cell according to the foam condition in the flotation cell; foam scraping is carried out on the foam generated in the flotation cell so as to obtain a monazite first ore concentrate product and a monazite tailing mineral product, wherein the foam scraping time is a third preset time; and magnetic separation is carriedout on the monazite first concentrate product according to a preset magnetic separation condition so as to obtain a monazite second concentrate product and a magnetic separation tailings product.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a beneficiation method for seaside placer. Background technique [0002] There are many kinds of useful minerals in seaside placer, but the composition of minerals is complex, and the process of sorting is complicated. For example, seashore placers include symbiotic monazite, ilmenite, zircon, rutile, etc., requiring multiple beneficiation methods and combined processes to separate the target minerals. [0003] At present, based on product trading requirements, monazite must be separated from ilmenite, zircon, and rutile during the mineral separation process, otherwise the product quality of zircon, ilmenite, and rutile will be affected, thereby reducing The economic value of raw materials affects the economic benefits of enterprises. [0004] At the same time, monazite is a kind of rare earth ore. In order to meet the needs of rare earth metallurgical production, th...
