Gold Ore Processing Flowchart

Step-by-Step with Branding

Stage 1: Baichy Precision Ore Pre-Processing

Baichy adopts a three-stage crushing process. The Baichy Jaw Crusher completes coarse crushing, followed by the Baichy Hydraulic Cone Crusher for medium/fine reduction. The system ensures a monomer dissociation degree >85% through closed-loop wet grinding in our overflow ball mills.

Stage 2: Intelligent Slurry & pH Conditioning

Through our online pH/ORP monitoring system, Baichy regulates the slurry concentration within the optimal 25-35% range. This stage utilizes advanced collectors (Xanthate) to enhance gold surface hydrophobicity (Contact Angle >65°).

Stage 3: High-Efficiency Flotation Separation

The core separation utilizes Baichy KYF aerated cells. By controlling aeration and impeller linear speed (6-8m/s), gold particles are selectively attached to microbubbles (0.8-1.2mm), forming a high-grade mineralized foam layer.

Stage 4: Concentrate Enrichment & Solid-Liquid Separation

Our multi-stage enrichment process increases concentrate grade to 40-80g/t. For tailings and concentrate management, we deploy Baichy High-Efficiency Deep Cone Concentrators, achieving a 70% underflow concentration for easier dehydration.

Stage 5: Final Metal Refining & Environmental Protection

The Baichy pyrometallurgical-wet system recovers gold with ≥99.99% purity. All processes are equipped with three-stage cyanide breaking devices and SO₂ flue gas treatment to ensure 100% environmental compliance.

Frequently Asked Questions

Q1: What is the typical gold recovery rate of  flotation system?

A: Baichy Heavy Industry's integrated gold flotation plant is engineered to achieve a gold recovery rate of over 98%. By optimizing the monomer dissociation degree (>85%) and utilizing advanced microbubble flotation technology, we minimize gold loss in tailings and maximize the final concentrate grade.

Q2: Which equipment is essential for the gold ore pre-processing stage?

A: A standard Baichy gold processing line includes a three-stage crushing system: a Jaw Crusher for coarse crushing, a Hydraulic Cone Crusher for medium/fine crushing, and an Overflow Ball Mill (equipped with a spiral classifier) for fine wet grinding. This configuration ensures the ore is reduced to less than 0.074mm (200 mesh) for optimal flotation.

Q3: How does Baichy handle ultrafine gold particles (-20μm) during flotation?

A: For complex ores with ultrafine gold, we implement cyclone microbubble flotation units and vertical mills for regrinding. This intensification process can increase the recovery rate of -20μm fine gold by 12-15% compared to traditional flotation methods.

Q4: Is  gold extraction process environmentally compliant?

A: Yes. Environmental protection is a core part of our solution. Our systems are equipped with three-stage cyanide-breaking devices for tailings treatment and SO₂ flue gas acid production systems for smelting. We ensure all solid-liquid separation and chemical processes meet international environmental standards.

Q5: Can Baichy provide a customized solution for different gold ore types?

A: Absolutely. Whether it's quartz vein gold, oxidized gold, or complex polymetallic ores, Baichy Heavy Industry provides tailored solutions based on professional mineral processing tests (MPTs). We offer full-chain services from equipment manufacturing to onsite installation and process optimization.
