lapis lazuli beneficiation production line and process flow

Solution for lapis lazuli beneficiation production line and process flow

1. Program Overview

This program provides professional lapis lazuli beneficiation production line and process solution for the characteristics of lapis lazuli ore. The main component of lapis lazuli is strontium sulfate (SrSO₄), with specific gravity of 3.9-4.0, which is mainly used in the manufacture of strontium carbonate and TV picture tube glass. According to the difference in specific gravity and embedded characteristics between lapis lazuli and veinstone, the process of multi-stage crushing with jigging gravity separation is adopted to realize efficient recovery of lapis lazuli concentrate.

2. Characterization of raw materials

The main characteristics of lapis lazuli ore:

• Specific gravity difference: the specific gravity of lapis lazuli is 3.9-4.0, and the specific gravity of veinstone is generally less than 3.0.

• Color: lapis lazuli is greenish-white, vein stones are dark gray.

• Characteristics of embedding: uneven distribution of coarse and fine grains, partly dipped

• Dissociation difficulty: need to be finely crushed to achieve a high degree of monomer dissociation.

3. lapis lazuli beneficiation process design

Raw material pretreatment stage
Raw ore is fed evenly by vibrating feeder, and then entered into jaw crusher for coarse crushing, and then entered into fine jaw crusher for fine crushing after coarse crushing, to ensure that the material reaches the appropriate particle size range.

Classification and Screening
After two-stage crushing, the material enters the circular vibrating screen for screening, and is divided into three grades: 0-8mm, 8-30mm and +30mm, of which the +30mm material returns to the crushing system for further crushing.

Coarse-grained sorting
The 8-30mm material enters the jigger for coarse-grained sorting. This jigger is specialized in handling coarse embedded ores, and can effectively recover the coarse-grained lapis lazuli that has been dissociated from the monomer.

Fine-grained processing
The 0-8mm grade material is combined with the tailings from the coarse-grained jigger and enters the impact crusher for fine crushing to ensure that the lapis lazuli is fully dissociated.

Fine-grained sorting
The finely crushed material enters the jigger for fine-grained sorting, and finally obtains pure lapis lazuli concentrate, and the tailings are discharged as waste.
