Gold Ore Mining Process and Machines
April 10, 2025
Summary：In this article, we’ll explore the gold ore mining process, the essential machines involved, and how our cutting-edge equipment—including jaw crushers, cone crushers, and screening machines—optimizes operations.
Introduction to Gold Ore Mining
Gold ore mining involves extracting gold-bearing rocks from the earth, followed by crushing, grinding, and beneficiation to extract pure gold. Efficient machinery, such as crushers, grinding mills, and screening equipment, is essential to increase productivity and reduce operational costs. As a leading manufacturer of stone crushers and screening machines, Liming Heavy Industry provides reliable and high-performance equipment for gold ore processing.
Gold Ore Mining Process
1. Exploration & Extraction
Gold deposits are identified through geological surveys. Once located, the ore is extracted through open-pit or underground mining methods.
2. Crushing & Grinding
The extracted gold ore must be crushed into smaller fragments before further processing.
- Primary Crushing: Large rocks are reduced to smaller pieces (150–250 mm) using a Liming C6X Series Jaw Crusher, known for its high efficiency and robust structure.
- Secondary Crushing: The material is further reduced using an HPT Hydraulic Cone Crusher or CI5X Impact Crusher, ensuring optimal particle size for grinding.
- Grinding: The crushed ore is ground into fine powder (100–200 mesh) using MW Series Micro Powder Mill or MTW European Trapezium Mill to liberate gold particles.
3. Screening & Classification
- S5X Vibrating Screen separates fine and coarse particles, ensuring proper sizing before leaching.
4. Gold Extraction (Cyanidation, Flotation, Gravity Separation)
- Carbon-in-Leach (CIL) or Flotation methods extract gold from the processed ore.
5. Smelting & Refining
The final gold concentrate is smelted into bars for commercial use.
