Gold Ore Fine Grinding Mill

-- Steady & Reliable Manufacturer --

Introduction

For refractory or finely disseminated gold ores, efficient fine grinding is not just beneficial—it's essential for achieving high recovery rates. Our gold ore fine grinding mills are designed to grind the ore to a specific target size (e.g., P80 of 75 microns or finer) to liberate microscopic gold particles ahead of leaching or flotation. By providing a consistent and well-controlled grind, our technology helps maximize the exposure of gold to the cyanide solution or flotation reagents, directly translating to higher gold recovery and improved project economics.

Applications

  • Carbon-in-Leach (CIL/CIP): Grinding ore to the optimal size for cyanide leaching and gold adsorption onto activated carbon.
  • Refractory Ore Processing: Ultra-fine grinding (UFG) of sulfide concentrates to liberate encapsulated gold before pre-treatment like oxidation.
  • Gravity Concentration: Grinding to a size that liberates coarse gold for recovery by gravity methods before leaching the tails.
  • Flotation Feed: Preparing the ore for flotation of gold-bearing sulfide minerals.

Advantages

  • Enhanced Gold Recovery: By preventing over-grinding and producing a consistent product size, our mills ensure optimal liberation, which can increase overall gold recovery by several percentage points.
  • Lower Reagent Consumption: A more uniform grind means less consumption of expensive reagents like cyanide and lime during the leaching process.
  • Energy Savings: Our modern grinding mills offer a more efficient grinding mechanism than older technologies, reducing the significant energy costs associated with fine grinding.
  • High Availability: Designed for the rigorous demands of a 24/7 gold mining operation, with features that allow for quick and easy maintenance of wear components.

Payment & Shipping

We offer flexible payment terms such as T/T and L/C to suit your project's financial structure. Our team provides end-to-end logistics solutions, including expert packaging in seaworthy materials and coordination with freight lines to ensure timely and secure delivery to your mine site, wherever it is in the world.

Frequently Asked Questions

  • Q: Why is minimizing over-grinding so important for gold processing?
  • A: Over-grinding creates excessive ultra-fine particles ("slimes"). These slimes can coat the gold particles, preventing them from dissolving in the cyanide solution. They can also adsorb gold themselves and cause issues in the downstream carbon circuit, leading to lower overall recovery.
  • Q: Can your mill be integrated into an existing grinding circuit?
  • A: Yes, our mills are highly versatile. They can be used as the primary mill in a new plant or integrated into an existing circuit, for example, as a regrind mill to process middlings from a flotation circuit, allowing you to debottleneck and improve the performance of your current operation.
