Zircon Sand Beneficiation Solution (Gravity + Magnetic + Electrostatic Separation)

Zircon sand beneficiation solution, zircon sand gravity-magnetic separation-electrostatic separation combined process

This zircon sand beneficiation solution provides a high-efficiency combined process centered on "wet gravity roughing + dry magnetic separation and electrostatic beneficiation" for zircon in seashore and river alluvial sands. Through multi-stage gravity enrichment, magnetic separation and electrostatic purification, it realizes efficient recovery and deep purification of zircon sand, and the content of ZrO₂ in the final product can be more than 65%.

I. Process Overview

Zircon sand is characterized by high density, weak magnetism and medium electrical conductivity, which is suitable for the combined process of "gravity pre-enrichment + magnetic separation / electrostatic purification". This zircon sand beneficiation solution realizes preliminary enrichment through wet gravity separation, and then deep purification through dry magnetic separation and high-pressure electrostatic separation, which has the characteristics of high recovery rate, excellent product quality, strong adaptability, etc. It can deal with the zircon sand with fine grain size of 0.1-0.5mm.

Second, process flow introduction

1. Wet roughing system

   • The raw ore is fed evenly through the silo and passed through the tumbler sieve (2-5mm hole) to classify and remove impurities;

   • The materials under the screen enter the spiral chute for roughing and sweeping (feeding concentration 30-40%), and initially enrich the zircon sand;

   • Gravity separation concentrate through the wet magnetic separator (field strength 1200-8000 gauss) to remove ilmenite, garnet and other magnetic minerals;

   • Finally, the shaking table is used to produce coarse zircon sand concentrate (ZrO₂ 50-55%).

2. Dry Concentration System

   • The coarse concentrate is dried by a dryer to create conditions for magnetic and electrostatic separation;

   • The dried material passes through the permanent magnetic drum magnetic separator to further remove the weak magnetic minerals;

   • Non-magnetic products enter the high-voltage electrostatic separator, utilizing the difference in electrical conductivity to separate zircon sand from rutile and other minerals;

   • Finally, the arc plate electrostatic separator or special magnetic separator for zircon ore is used for fine removal of impurities to obtain high purity zircon sand concentrate (ZrO₂≥65%).

3. Tailings and water recycling system

   • The utilization rate of process water recycling in the wet section is >90%, reducing water consumption;

   • Tailings are stockpiled or backfilled after dewatering treatment, in line with environmental protection requirements.
