Diamond Beneficiation Solutions

Diamond Beneficiation Solutions

I. Program Overview

The diamond beneficiation solution designs differentiated beneficiation process according to the different characteristics of primary diamond ore and alluvial diamond ore. The primary ore adopts the "segment crushing - stage separation" process, while the alluvial ore adopts the "washing - screening - gravity jigging" process, which is complemented by specialized rougher and concentrator equipment to realize the efficient recovery of diamonds.

Process Flow

1. Primary Ore Beneficiation Process

   • Three-stage crushing system:

     • Rough crushing (jaw crusher) to -50mm

     • Medium crushing (cone crusher) to -20mm

     • Fine crushing (high pressure roller mill) to -10mm

   • Stage jigging separation:

     • After each stage of crushing, a jigger is equipped to recover dissociated diamond in time.

     • Jigging tailings go to the next stage of crushing/grinding.

   • Grinding classification:

     • Ball mill and cyclone closed circuit grinding (to -2mm)

     • Jigging after classification to recover fine-grained diamonds

2. Alluvial beneficiation process

   • Washing and screening:

     • Rotary scrubber to remove clay

     • Vibrating screen classification (+5mm/-5mm)

   • Jigging roughing:

     • Small jigger for 0-10mm particles

     • Medium-sized jigger for 0-30mm particles

   • Oleomargarine Concentration:

     • Vibrating oil paste concentrator sorting

     • Get the final diamond concentrate

Third, the core equipment configuration

Fourth, technical indicators

• Processing capacity: 10-350t/h (customized according to ore type and scale)

• Processing particle size: 0-30mm full grain size

• Energy consumption: only 1/3 of heavy media beneficiation

• Water consumption: recycling utilization rate ≥90

V. Program Advantages

• ✅ High-efficiency recycling: segmented crushing + stage jigging ensures early and high recovery, adapting to 0.5-30mm full-grain recycling.

• ✅ Economical and practical: low running cost of jigger, saving investment in oil paste beneficiation equipment.

• ✅ Stable and reliable: simple equipment structure, low failure rate, easy operation and maintenance.

• ✅ Environmental protection and energy saving: no chemical additives, recycling of wash water, reusable oil paste.

• ✅ Strong adaptability: adapted to all kinds of diamond deposits, can flexibly adjust the process according to the characteristics of the ore.
