Embodiment Construction

[0031] The present invention is described in further detail now in conjunction with embodiment.

[0032] A novel lepidolite flotation method, such as figure 1 As shown, it mainly includes three desliming, one roughing, two refining and one sweeping.

[0033] Specific steps are as follows:

[0034] 1 desliming three times

[0035] 1.1 The first desliming of raw ore with cyclone

[0036] 1.2 The first desliming product uses a hydraulic classifier for the second desliming

[0037] 1.3 Use the hydraulic classifier again for the third desliming

[0038] After the above three times of desliming, more than 90% of the slime less than 0.010mm is removed, and it becomes the ore feed for roughing

[0039] 2 rough selection

[0040] 2.1 Use a mechanical flotation machine to float the deslimed product, add hydrochloric acid 3000-5000g / t, stir for 2-6 minutes, and adjust the pH value of the pulp to 2-3.

[0041] 2.2 Then add 3000-4800g / t collector XLD-152 and stir for 1-2 minutes. Af...

Abstract

The invention discloses a novel lepidolite floating selecting method, a collecting agent and application of the collecting agent. The novel lepidolite floating selecting method comprises the steps of removing sludge at three times; roughly selecting once; fine selecting twice; scavenging once; before floating selecting, hydrochloric acid is added to regulate the pH of ore pulp to be 2 to 3; the collecting agent is adopted during rough selecting and scavenging; the total quantity of used lauryl amine or coconut amine; the collecting agent is prepared from the following components in percentage by mass: 1% of lauryl amine or coconut amine, 1 to 5% of ethyl alcohol, 1 to 2% of hydrochloric acid, and 92 to 97% of water. The method has the characteristics of being simple in process, small in agent consumption, small in floating selecting time, and small in production cost; the recovery rate of lepidolite concentrate is more than 90%; the Li2O content in lepidolite concentrate product is more than 5.6%; therefore, the comprehensive utilization value of a lepidolite resource can be obviously increased; in addition ,the method is environmentally friendly, and is of significance on long-term sustainable development and practical significance.

Description

technical field [0001] The invention relates to a lepidolite flotation method, a collector and applications thereof. technical background [0002] Lepidolite is one of the main industrial minerals for extracting lithium. Lithium is an important energy metal. Its application in high-energy lithium batteries and controlled thermonuclear reactions makes it an important raw material to solve long-term energy supply for human beings. Lithium series products are widely used in smelting, refrigeration, atomic energy, aerospace and ceramics, glass, grease, rubber, welding, medicine, batteries and other industries. my country's lithium resources are relatively rich, but the grade is relatively low, the embedded particle size is fine, and the utilization level is low. The resource advantage has not yet been transformed into an economic advantage. [0003] Different lithium ores have different properties. Due to the different contents of lithium oxide in the minerals and the differen...
