Ruby beneficiation production line and process

Ruby Beneficiation Production Line and Process Solution

Ruby beneficiation is based on the core process of "washing-screening-gravity separation-photoelectric/oil paste sorting", which ensures the efficient recovery of high-grade rubies while maximizing the protection of the integrity of gemstone crystals.

I. Ruby beneficiation process

1. Washing and screening system

Purpose: To remove clay, sand and surface adherents, and improve the efficiency of subsequent sorting.

• Rotary scrubber (with high-pressure water spray):

  • Processing capacity: 20-100 t/h

  • Remove -0.5mm fine mud to prevent clogging of subsequent equipment

• Double-deck vibrating screen (stainless steel screen):

  • Grading size: +5mm, 5-2mm, 2-0.5mm, -0.5mm

  • Screened material (+5mm) manual picking to remove large waste rock

2. Gravity enrichment system

Purpose: Pre-enrichment utilizing the density difference between ruby (density 3.9-4.1 g/cm³) and quartz/feldspar (density 2.6-2.8 g/cm³).

• Jigger (sawtooth wave type):

  • Processing 5-0.5mm grain size, recovery rate of more than 85%

  • Stroke, stroke adjustable, adapted to different particle size ruby

• Spiral concentrator (for -0.5mm fine grain size):

  • Recover micro-fine grained rubies, reduce losses

3. Selection and purification system

Purpose: To further improve the purity of ruby, remove garnet, spinel and other associated minerals.

• Shaking table selection (6-S type fiberglass shaking table):

  • Processing jigging rough concentrate, improving ruby grade

• Optical sorting machine (X-ray/XRF/Laser sorting):

  • Sorting based on the Cr elemental characteristics or fluorescence properties of ruby.

  • Purity up to 98% or more, processing capacity 1-10 t/h

• Vibrating Oil Paste Concentrator (optional):

  • Utilizing the difference in surface adhesion between ruby and impurity minerals for sorting

  • The recovery rate can reach more than 95%.

Second, the main equipment configuration of ruby production line

Third, the process advantages of ruby beneficiation production line

✅ High efficiency recovery

• Combination of jigging + photoelectric sorting, recovery rate >90%

• Adaptable to 0.5-30mm full-grain rubies

✅ Economic and energy saving

• Low operating cost of jigger, energy consumption is only 1/3 of heavy media beneficiation.

• The oil paste can be reused, reducing the cost of consumables.

✅ Environmental protection and safety

• No chemicals, recycling of washing water

• Photoelectric sorting without pollution, in line with environmental requirements

✅ Stable and reliable

• Simple equipment structure, low failure rate

• Simple operation and maintenance, adaptable to all kinds of alluvial ores
