In the gold mining industry, efficient mineral processing is the core for profitability and resource utilization. The selection of appropriate crushing and grinding equipment directly impacts recovery rates, operational costs, and overall plant productivity.
A typical gold ore processing flowsheet includes crushing stage, grinding stage, separation, and tailings processing. What equipment is used in gold ore processing? Here, we mainly talk about the crushing and grinding stage.
1. Crushing Stage:
Primary Crushing – Jaw Crusher. Jaw crusher has large crushing ratio, simple structure, which is used to break large raw materials (≤1500mm) into small pieces.
Secondary Crushing – Cone Crusher. After primary crushing, the secondary and tertiary crushing stages demand precision, reliability, and the ability to produce a consistent, well-shaped product. This is where the Cone Crusher excels and is the recommended choice.
Why Cone Crushers are Ideal for Gold Ore:
Lamination Crushing: Cone crushers operate by compressing rock between a rotating mantle and a stationary concave liner. This method is exceptionally effective for the hard, abrasive ores typical of gold deposits (e.g., quartz-rich veins), minimizing wear and producing fewer abrasive fines compared to impact crushing.
Operational Automation: Modern hydraulic cone crushers offer automated settings adjustment, overload protection, and real-time monitoring. This ensures consistent product size, maximizes uptime, and allows for seamless integration into automated plant control systems.
Versatility for Fine Crushing: Especially in the tertiary stage, cone crushers can be configured to produce a fine feed (often below 20mm), creating the ideal “prepare for grinding” size, which significantly reduces the workload and energy draw of the grinding mills.
2. Grinding Stage:
Ball mill is a rotating cylinder filled with steel balls that cascade and impact the ore, providing a combination of impact and abrasion. It is unparalleled for producing the very fine product required for gold ore processing. Ball mill has high capacity, ability to achieve a very fine grind, and suitability for both wet and dry grinding.
