Gold Recovery from Crushed Quartz: Equipment and Process

Crushed quartz is a common host rock for gold deposits, requiring specialized processing equipment to maximize recovery. A well-designed production line integrates crushing, screening, and gravity separation technologies.

Key Equipment for Quartz Processing

1. Jaw Crusher: Primary reduction to 100-150mm
– Model example: JC5460 (500TPH capacity, 250kW motor)
2. Cone Crusher: Secondary crushing to 20-50mm
– HP400 model (315kW, closed-side setting 10-50mm)
3. Vertical Shaft Impact Crusher: Produces cubical sand (-5mm)
– VSI1145 (400TPH, dual 250kW motors)

Gold Recovery System

The downstream circuit typically includes:
– High-frequency screens ( Stack Sizer)
– Knelson concentrators (KC-QS48 model)
– Shaking tables (Deister #999)

Frequently Asked Questions

Q: What’s the optimal quartz size for gold recovery?

A: Gravity separation works best with 1-10mm particles after proper liberation.

Q: How to prevent gold loss in fines?

A: Install fine recovery systems like centrifugal concentrators for -100µm particles.
