Tungsten Ore Beneficiation Solution: Professional Process for Highly Efficient Recovery of Wolframite and Scheelite

As an important strategic mineral resource, tungsten ore beneficiation process varies significantly depending on the type of mineral. This paper focuses on the core theme of "tungsten ore beneficiation solutions", and introduces in detail the specialized beneficiation process for wolframite and scheelite, including the core technologies of re-election and flotation, as well as the configuration of ancillary equipment and technical advantages, to provide a comprehensive solution for the efficient recovery and comprehensive utilization of tungsten ore resources.

I. Characteristics and Challenges of Tungsten Ore Beneficiation

Tungsten ore is mainly divided into two categories: wolframite and scheelite, and its beneficiation faces the following challenges:

• Wolframite: usually adopts re-election as the main method, but there are problems such as difficulty in recovery of fine-grained grade and complexity of associated minerals.

• Scheelite: mainly adopts flotation process, but it needs to solve the problem of separating calcium and magnesium minerals such as calcite and fluorite.

• Complex symbiotic relationship: often symbiotic with a variety of non-ferrous metal minerals, need to be comprehensive recycling.

Second, wolframite beneficiation solutions

1. Roughing stage

• Dynamic screen jigger handles fine-grained materials to realize pre-enrichment.

• The output of qualified ore goes into the next process, improving the overall processing efficiency.

2. Re-election stage

• Multi-stage jigger series sorting, improve sorting efficiency

• Multi-stage shaking table fine sorting, to ensure the concentrate grade

• Middle ore regrinding and re-election closed loop, maximize the recovery rate

3. Selection stage

• Floatation-heavy combined process for complex minerals

• Floatation-heavy-magnetic process realizes comprehensive recovery of multi-metals.

• Effective recovery of associated valuable elements to enhance economic benefits

4. Fine Mud Treatment

• Desulfurization pretreatment to improve sorting effect

• Heavy/flotation/magnetic separation combined process to recover fine tungsten minerals

• Centrifugal concentrator specializes in handling fine-grained materials.

Solution of scheelite beneficiation

1. Separate scheelite from calcite and fluorite.

• Concentrate the slurry to 60-70% concentration

• Water glass slurry mixing, 80℃ high temperature stirring

• Flotation of scheelite at room temperature to realize effective separation.

2. Separation of scheelite and barite

• Alkyl sulfate collector selective capture

• Sorting under acidic condition of PH=1.5-3.0

• Multiple selections to ensure the separation effect

3. Separation of scheelite and sulfide ore

• Flotation to remove sulfide ore

• Cyanide/sodium sulfide inhibits impurity minerals

• Specialized in scheelite flotation

4. Separation of scheelite and silicate

• Oleic Acid Capture Agent Selectively Capture Scheelite

• Water glass inhibitor to inhibit quartz silicate

• Multi-stage selection to improve the quality of concentrate
