Global Gold Mining EPC Solutions | Turnkey Gold Processing Plant

Have you ever struggled with purchasing gold mining equipment that didn’t meet your needs? What should you do when faced with incompatible parts, low production efficiency, and wasted capital? Chunlei Machinery is not only a supplier of ball mills and leaching tanks, but also a one-stop EPC partner for large-scale gold mines (with a daily processing capacity of 100 tons or more).

We offer comprehensive services: free ore sample testing, customized process design, complete equipment manufacturing, global logistics, on-site installation, operator training, and long-term after-sales support. With us, you no longer need to coordinate with multiple suppliers for a single project, allowing you to focus on expanding gold production and increasing profits.

In this article, we will introduce:

Why choose our EPC solutions?

We specialize in large-scale gold mining projects (with daily processing capacities ranging from 100 to 5,000 tons)—this is where our expertise lies! Here are our unique advantages:

✅ Full lifecycle support. From laboratory analysis of ore samples to the final commissioning of the plant, we cover every step of the process. No more headaches coordinating different suppliers—we serve as your single point of contact for the entire project.
✅ Customization for large-scale projects. Every mine is unique, and so should your processing line be! Our engineers will tailor solutions based on your ore type, grade, and local environmental regulations and conditions. We also design modular processing lines that can scale up as your production grows.
✅ World-class gold processing expertise. We have extensive experience in optimizing core processes: ball milling, CIL/CIP leaching, carbon-in-pulp leaching, and flotation. We have helped clients increase gold recovery rates by 5–10% and reduce energy consumption by up to 25%.
✅ Global installation experience. We have successfully delivered multiple EPC projects in Southern Africa, Southeast Asia, and South America. Our local teams understand the operational nuances of remote mining sites, ensuring safe and on-time project delivery.

Our Complete Gold Processing Production Line

We don’t just sell individual pieces of equipment; we build complete, integrated gold processing production lines that work seamlessly together. Here is the complete project workflow:

Step 1: Ore Sample Testing and Feasibility Study

We will test your ore samples free of charge to determine gold grade and ore hardness, the optimal crushing/leaching method (CIL, CIP, heap leaching), detailed recovery rates, energy consumption, and project cost estimates.
You’ll receive a clear feasibility report before investing a single penny.

Step 2: Crushing and Grinding

This is the foundation for achieving high gold recovery rates! Our production lines include:
Primary jaw crushers and secondary/tertiary cone crushers, as well as energy-efficient ball mills/rod mills (which grind the ore to the optimal particle size for gold liberation).
We optimize mill designs to reduce energy consumption by 20% compared to standard models.

Step 3: Leaching and Gold Recovery

Extract gold from ore using our complete systems:
CIL/CIP Plant: Suitable for high-grade ore—includes leaching tanks, carbon columns, and electrowinning units (for rapid gold recovery!).
Heap Leaching System: Suitable for low-grade ore—modular, cost-effective, and easy to install.
Gold Refining: Refines gold into 99.99% pure gold bars ready for direct sale.

Step 4: Environmental Sustainability and Automation

Eco-friendly Design: Thickeners, filter presses, and water recirculation systems reduce water consumption by 40% and comply with global environmental standards.
Intelligent SCADA Control System: Monitors plant load, leaching pH, and flow rates in real time. Alerts are triggered when equipment issues arise to minimize downtime.

Our Success Story: 200 TPD Plant in Southern Africa

Let’s walk through a recent project we delivered to show what we can do:

Client Needs

A Southern African mining company wanted to upgrade their old, fragmented setup to a 200 TPD modern gold processing line. They wanted higher recovery rates, lower costs, and on-time delivery.

What We Did

We provided a FULL EPC package:

• Custom process design (based on their ore sample)
• Supply of ball mill line + CIL leaching plant
• Logistics to their site + customs clearance
• On-site installation, operator training, and 12-month after-sales support

Results That Matter

🚰 40% Less Water Use: Recycled water, stayed compliant with local rules.y-saving design not only reduces operating costs but also ensures stable grinding speed, directly improving gold recovery by 2-3%.

📈 Gold Recovery Rate: Jumped from 85% to 92% (more gold, more profit!).

💰 25% Less Energy Use: Saved money on power bills per ton of ore.

⏱️ 6-Month Delivery: Finished 3 months early—started producing gold sooner!
