How to choose a gold mine crusher in South Africa

Choose a right gold mine crusher in South Africa involves considering several factors to ensure efficient and cost-effective mining operations.

Understand the Gold Ore Type

Because different gold ore types require different crushers:

  • Hard Rock Gold Ore: Requires heavy-duty crushers like çeneli kırıcılar, konik kırıcılar, veya darbeli kırıcılar.
  • Soft Gold Ore: May require a combination of crushers, such as hammer crushers or roll crushers.
  • Oxidized Ore or Alluvial Gold: Typically easier to process; choose equipment designed for fine crushing or gold extraction.

How to judge the hardness of gold ore?

Compare the ore with minerals on the Mohs scale1 (1–10). Gold itself has a Mohs hardness of 2.5–3, meaning it’s relatively soft. Assess the accompanying minerals (e.g., quartz has a Mohs hardness of 7, pyrite 6–6.5). If the ore contains significant quartz or other hard minerals, it will generally be harder.

  1. Scratch Test: Use a steel knife or other known materials to scratch the ore. Observe whether the ore scratches easily or resists the scratch.
  2. Hammer or Impact Test: Strike a piece of the ore with a hammer. Harder ores will fracture into angular pieces, while softer ores may crumble or deform.
  3. Crushability Test: Manually crush a small piece of ore using a pestle and mortar. Softer ores will break down easily, while harder ores will require more effort.
  4. Rebound Hardness Test: Use a portable Schmidt hammer to measure the rebound value of the ore surface. Higher rebound values indicate greater hardness.

Crusher Types

There are many types and models of stone crushers. So you should choose a gold mine crusher from these crusher types:

  • Jaw Crushers: Ideal for primary crushing. They can handle large rocks and provide a solid base for secondary crushing.
  • Cone Crushers: Good for secondary and tertiary crushing. Suitable for producing fine particles.
  • Impact Crushers: Effective for medium hardness materials and generating uniform sizes.
  • Hammer Crushers: Excellent for softer materials and for producing finer output.
  • Mobile Crushers: Flexible and cost-effective for remote gold mines.

Capacity Requirements

You should first figure out what capacity you need. Then choose the appropriate gold ore crusher according to the capacity you need.

  • Small-scale operations may use compact crushers.
  • Large-scale mining requires high-capacity crushers to process more material.

Efficiency and Energy Consumption

Energy-efficient crushers reduce operational costs, particularly in South Africa, where energy prices can be high. Look for crushers with:

  • Low energy consumption.
  • High crushing efficiency.

Durability and Maintenance

South Africa’s mining conditions can be harsh, so choose crushers made of durable, wear-resistant materials.
Opt for equipment that’s easy to maintain and has readily available spare parts locally.

Budget and Costs

Factor of Choose a gold mine crusher in:

  • Initial purchase cost.
  • Installation cost.
  • Maintenance and operational costs.

Vendor Reputation and Support

Purchase from reputable manufacturers or local distributors who provide after-sales service.
Check for local availability of spare parts and technical support.

Environmental Regulations

Ensure the crusher complies with South Africa’s environmental and mining regulations, such as dust and noise control measures.

A well-known supplier in the region include:

  • SBM Makina: Offers a range of crushing solutions for mining, Known for robust and energy-efficient equipment.

  1. Mohs hardness is a mineral hardness scale that uses the relative scratch hardness of minerals. It was proposed by German mineralogist Friedrich Mohs in 1812. Mohs hardness is a relative scale and has no direct proportional relationship with absolute hardness. ↩︎
