galena gravity beneficiation solutions

Gravity Separation Solution for Galena Ore

This solution provides professional, efficient and environmentally friendly gravity beneficiation process solutions for galena ore with coarse-grained embedded characteristics. Through the processes of crushing, screening, rough grinding and jigging, the recovery rate of lead can be significantly improved, and the investment and operation costs can be minimized. The solution of galena gravity separation is suitable for the beneficiation projects with moderate grade, large embedded particle size and strict environmental protection requirements.

I. Characteristics of raw materials and applicable conditions

PbS has significant advantages in gravity beneficiation:

• Large specific gravity (7.4-7.6 g/cm³), obvious difference with vein minerals;

• Coarse-grained embedded, complete crystallization and good dissociation;

• Strong friability, need to effectively prevent and control over-crushing.

✅ Applicable ore types:

• Galena crystallization grain size>0.5mm;

• The structure of the original ore is relatively simple, and the veins are easy to separate;

• Projects with high environmental requirements and need to control the use of pharmaceuticals.

Second, the process is briefly described

1. Crushing and screening: after coarse crushing by jawbreaker, the raw ore is graded by circular vibrating screen, and the materials not up to the standard are returned to fine crushing, forming a closed-circuit cycle to enhance the crushing efficiency.

2. Rough grinding: rod mill is used for rough grinding to protect the crystal structure of minerals and avoid over-crushing.

3. Jigging separation: the material enters the jig machine, relying on the difference in specific gravity to efficiently separate the lead concentrate and tailings.

4. Dewatering treatment: the concentrate is separated from the solid-liquid by dewatering screen to get the finished product.

Third, the core advantages of gravity separation process

• ✅ Low investment cost: equipment investment is 40-50% lower than that of flotation process;

• ✅ Saving operation cost: low energy consumption, easy maintenance, reducing the comprehensive cost by 30-40%;

• ✅ Green environmental protection: the whole process does not require chemicals, no pollution emissions;

• ✅ Strong adaptability: especially suitable for coarse embedded galena, high recovery efficiency;

• ✅ Stable index: concentrate lead grade can be up to 65% or more, processing capacity of 5-200 tons/hour can be customized.

IV. Core Equipment Configuration

• Jaw Crusher - High efficiency coarse/fine crushing;

• Circular Vibrating Screen - Particle size classification and closed circuit control;

• Rod mill - coarse grinding protection against over-crushing;

• Jigger - core sorting equipment with high recovery rate;

• Dewatering screen - concentrate dewatering, finished product preparation.

V. Outstanding economic benefits

• Significantly reduced initial investment, suitable for projects with limited budget;

• Controllable operating costs, low energy consumption and labor requirements;

• No need for pharmaceuticals, saving subsequent environmental protection treatment costs;

• High resource utilization rate, fast return on investment.
