The 50 TPH gold ore crushing production line is a standardized solution from Baichy Heavy Industry designed for small-to-medium-scale gold mining projects. It covers the entire process—primary crushing, secondary/fine crushing, and screening—for primary gold ores (quartz vein and altered rock types), delivering feed material with optimal particle size and sufficient gold liberation for subsequent grinding and leaching stages.
| Ore Type | Mohs Hardness | Abrasiveness | Suitability |
| Quartz vein gold ore | 6–7 | Medium–High | Jaw crusher + cone crusher combo; highly wear-resistant Mn18Cr2 jaw plates |
| Altered rock gold ore | 5-6 | Medium | Inter-particle (lamination) crushing reduces over-grinding and preserves gold particle liberation |
| Oxidized gold ore | 3–5 | Low–Medium | Impact crusher (PF1010) can replace cone crusher to lower investment costs |
| Sulfide-bearing gold ore | 5-7 | Medium–High | Enclosed screening system + dust collector to meet environmental standards |
Traditional impact crushers rely on high-speed impact; when crushing gold ore, this tends to flatten coarse gold particles or drive them into gangue fissures, reducing subsequent leaching recovery rates. Baichy’s "Jaw Crusher → Cone Crusher" combination utilizes the principle of inter-particle (lamination) crushing. Ore undergoes mutual compression and grinding between particles within the crushing chamber, allowing gold particles to liberate along mineral grain boundaries rather than being forcibly shattered.
The 2YK1545 double-deck vibrating screen enables closed-circuit screening: the top deck (50mm aperture) limits the maximum feed size for the mill, while the bottom deck (15mm aperture) separates fine material. Oversized material is automatically returned to the cone crusher for re-crushing, ensuring that 100% of the ore entering the ball mill meets design specifications. Practical benefits of closed-circuit screening:
• Improved grinding efficiency: Reducing the mill feed size from 80 mm to 50 mm increases the ball mill's processing capacity by 18–22%.
• Reduced steel ball consumption: Eliminating the need for large-diameter balls to break down oversized ore fragments reduces steel consumption by 10–15%.
• Extended liner service life: Uniform feed size and stable mill loading extend the liner replacement interval by 20%.
No two quarries are the same. That's why every Baichy configuration starts with your raw material and target capacity — never a catalog template. The installations below are just a sample. Your project could be the next one on this list.
Gold Ore Flotation Extraction Plant & Equipment Solutions
1. Conventional process (applicable to high-grade gold ore)
Ore → coarse crushing (jaw crusher) → medium crushing (cone crusher) → fine crushing → ball milling → flotation/cyanidation → smelting
2. Low-grade gold ore (heap leaching)
Ore → coarse crushing → fine crushing → heap building → spray cyanidation → activated carbon adsorption → electrolytic gold extraction
