Ruby Gravity Separation Solutions

Ruby Gravity Separation Solution

This ruby beneficiation solution provides a high-efficiency process centered on "washing-screening-gravity beneficiation" for the mineral characteristics of ruby. Through physical methods to remove clay, sand and other impurities, using the density difference between ruby and vein minerals to achieve efficient separation and enrichment, to ensure high recovery while maximizing the protection of the integrity of gemstone crystals.

I. Process Overview

Ruby is characterized by high density (3.9-4.1 g/cm³) and high value, which makes it suitable for the physical separation process mainly based on gravity separation. This ruby gravity beneficiation solution realizes the efficient recovery of ruby through washing and screening pretreatment, jig roughing and shaking table selection, which has the advantages of investment saving, environmental protection and no pollution, and good crystal protection, etc. It is especially suitable for alluvial ruby deposits.

Second, the process flow introduction

1. Washing and screening system

   • Raw ore enters the rotary scrubber (with high-pressure water spray), effectively removing 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 ruby from quartz, feldspar and other light minerals;

   • -0.5mm fine-grained grade can be recovered by spiral concentrator to reduce the loss of micro-fine-grained gemstones;

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

3. Tailings treatment and water recycling

   • After sorting, the tailings are treated by dewatering screen and then stockpiled or backfilled;

   • Process water is recycled to reduce water consumption.

Third, the core equipment configuration

Main technical indicators

• Processing capacity: 20-150 t/h (can be customized)

• Recovery rate:

  • Gem-grade ruby (0.5-30mm): 85-95%

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

• Concentrate purity: ≥95% (industrial grade)

• Water recycling rate: ＞85%

V. Program Advantages

• ✅ High-efficiency recovery: jigger + shaking table combination, adapting to full-grain sorting, high recovery 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 methods maximize the protection of ruby crystal integrity;

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