What are the floating steps of lithium ore?

246 2.Mar.2023 KZ Editor

Lithium ore is one of the main sources of lithium and is produced in Baiyun Mother and Lithium Cloud Mother -type granite. It is often symbiotic with lithium cloud mother, green pillar, iron ore, electrical stone, and white cloud mother, and belongs to silicate minerals with these pulse minerals. Lithium ore flotation plant often uses lithium ore floating technology to purify lithium ore. Let ’s take a look at the flotation technology of lithium ore.

Lithium ore flotation technology

Lithium flotation technology mainly refers to foam floating technology. The floating process of lithium ore generally includes the following operations.

1. grind

The ore is the first grinding of lithium minerals from other minerals (or pulse minerals).

2. Tie and drugs

Adjust the concentration of the slurry to meet the flotation requirements and add the required floating reagents to improve efficiency.

3. Floating separation

The slurry expands and floats in the floating machine to complete the separation of minerals.

4. Dehydration separation

The floating foam products and tailings are dehydrated and separated.

The floating process of lithium ore mainly affects the nature of ore, milling fineness, stirring operation, adjustment agent ratio, water quality hardness, etc. Pure pyloric minerals are not polluted on the surface, and it is easy to float with oleic acid and soap.

The optimal pH value of flotal slurry is close to neutral weak alkali. Na2CO3 should be added before flotation of the power pyri to eliminate the impact of salt ions in the slurry and mix off the mud. The surface of the lithium ore (lithium ore) should be added with the technical principles of strong alkaline lithium ore formed by NaOH

The slurry (ore generally comes from classification or concentration operation) consisting of solid lithium mineral particles and water (ore slurry usually comes from classification or concentrated operations) should be tuned with appropriate flotal agents in the mixing groove. If necessary, use some process to return water (such as filter liquid) or water to adjust the concentration of the slurry to meet the floating requirements. The main purpose of mixing the slurry with the flotant agent is

a) Add a collection or activator to increase hydrophobicity on the surface of the snorkeling.

b) Add inhibitors to make the surface of minerals that do not want to float more hydrophilic and suppress its floating.

c) Add foaming agents to promote the formation and decentralization of bubbles.

The adjusted slurry is sent to a flotal groove, and the grooves that are rotated at the same time are inhaled and floated in the flotal groove. The air was crushed into many bubbles by mud flow. The foaming agent promotes the formation and decentralization of micro -bubbles.

In the slurry, bubbles collide with ore particles. The difference in hydrophilicity on the surface determines whether the ore particles are attached to the surface of the bubble. The ore particles with strong hydrophobicity are attached to the surface of the bubble, which is carried by bubbles and rises to the surface of the slurry to form a foam layer. The bubbles shaved are called lithium concentrates. The particles with strong hydrophilicity on the surface do not interact with the slurry. NaOH's amount determines the recovery rate of lithium ore.
