Gemstone Sand Ore Gravity Separation Solutions

Gemstone Alluvial Ore Gravity Beneficiation Solution

This Gemstone Beneficiation Solution provides a highly efficient process centered on "Washing-Screening-Gravity" for the characteristics of ruby, sapphire, garnet and other precious gemstone alluvial ores. Through the physical sorting method, under the premise of ensuring the integrity of gemstone crystals, it realizes the efficient recovery of high-grade gemstones, which has the advantages of investment saving, low operation cost, environmental protection and no pollution.

I. Process Overview

Gemstone sand ore is characterized by high density and high value, which is suitable for the physical separation process mainly based on gravity separation. This gravity separation program for gemstone alluvial ores realizes efficient recovery of gemstones through washing and screening pretreatment, jig roughing and shaking table selection, which is especially suitable for alluvial gemstone deposits, and can deal with materials of all grain sizes from 0.5 to 30mm.

Second, process flow introduction

1. Washing and screening system

   • Raw ore enters into the rotary scrubber, through the high-pressure water spraying to effectively remove the clay and surface adherents;

   • The washed material is graded by double-deck vibrating screen (+5mm, 5-2mm, 2-0.5mm, -0.5mm);

   • The +5mm screened material can be manually picked to eliminate the large waste rock and improve the subsequent sorting efficiency.

2. Gravity enrichment system

   • 5-0.5mm grain size material enters the jigger, utilizing the density difference to separate gemstones and vein minerals;

   • The -0.5mm fine-grained grade is recovered by spiral concentrator to reduce the loss of fine-grained gemstones;

   • The jig concentrate enters the shaking table for selection to further improve the grade of gemstones.

3. Tailings treatment and water recycling

   • After sorting, the tailings are dewatered and then stockpiled or backfilled;

   • Process water is recycled to reduce water consumption.

III. Core Equipment Configuration

Main technical indexes

• Processing capacity: 20-300t/h (can be customized)

• Recovery rate:

  • Gemstone grade product (0.5-30mm): 85-95

  • Industrial-grade products (-5mm): 90-98%

• Water recycling rate: >85%

V. Program Advantages

• ✅ High-efficiency recycling: jigger + shaker combination, adapting to full-grain sorting, high recycling rate;

• ✅ Economic investment: low investment in equipment, low operating costs, energy consumption is only 1/3 of heavy media beneficiation;

• ✅ Environmental protection and safety: no chemicals in the whole process, water recycling, in line with environmental requirements;

• ✅ Protection of crystals: physical sorting method maximizes the protection of gemstone crystal integrity;

• ✅ Stable and reliable: the equipment has a simple structure, low failure rate, and adapts to all kinds of alluvial conditions.
