Flotation process of lepidolite beneficiation equipment: Generally, lepidolite beneficiation plants will use flotation to sort lithium ore. The specific process is as follows: the concentrated and deslimed lithium pulp will enter the flotation machine for a rough separation. After roughing, lithium rough concentrate will enter the next step of beneficiation. The coarse tailings will be scavenged. When selecting lithium, three selections are generally used. Such three times of beneficiation can improve the recovery rate of lithium concentrate and avoid waste of materials. The lithium after beneficiation is the concentrate product, which can be transported to the concentrate warehouse for storage for the next step of processing.

The main method of lepidolite positive flotation: Add sodium hydroxide to the pulp at the beginning to stir and scrub to remove surface pollutants. The treatment after desliming and ore washing is divided into three categories:

1. Lepidolite beneficiation equipment starts with pumice mica, then spodumene, and finally pumice feldspar. The steps are:

①. In weakly acidic medium, use cationic pumice.

②'Concentrate the flotation tailings to 50% solids, mix with oleic acid collectors and alcohol foaming agents, dilute to 17% solids, and use pumice spodumene.

③. After the spodumene-floated tailings are treated with hydrofluoric acid, a cationic collector is added to float the feldspar.

2. Lepidolite beneficiation equipment first pumice spodumene, then pumice mica, and then pumice feldspar. The steps are:

①. Concentrate the pulp to 64% solids, stir with oleic acid, sulfuric acid and foaming agent, then dilute to 21% solids, pumice spodumene.

②. Mica in spodumene flotation tailings is floated out with cationic collector.

③. Mica flotation tailings are added with hydrofluoric acid to activate feldspar, and cationic collector pumice feldspar is added.

3. The lepidolite beneficiation equipment line mixes spodumene and mica for flotation, and finally pumice feldspar. The steps are:

①. Add sulfuric acid to the thick slurry to adjust, then add anion collector to float mica and spodumene.

②. The mixed concentrate is stirred in the acidic medium to float mica and iron-containing minerals, and the product in the tank is spodumene.

③. After mixing the tailings after flotation, add hydrofluoric acid to treat them, and then use cationic collector pumice feldspar.

The beneficiation of lepidolite beneficiation equipment requires multiple steps of coarse crushing, fine crushing, magnetic separation and flotation. The steps are carried out separately, and the continuity between each step is strong, thus improving the beneficiation efficiency of lepidolite , and each crushing system needs an independent power source to drive the system to run, which improves the system linkability, reduces the difficulty of follow-up maintenance, and facilitates the follow-up maintenance of the system. At the same time, the existing flotation system is When producing foam, it is necessary to generate foam inside the flotation box, and then collect the foam. When producing foam, it is necessary to stir the mixture. It is necessary to ensure that the upper liquid level of the mixture is lower than the flotation box to prevent overflow, so that the foam inside the flotation box is completely and effectively collected, thereby It will not cause waste of some resources.

Lepidolite beneficiation equipment combination: jaw crusher, ball mill, classifier, mixing tank, flotation machine, concentrator, dryer, etc., basically arranged in the order in which the equipment appears in the production line. Production line process: "raw ore→crushing→grinding→flotation→dehydration→finished ore concentrate".
