Gold Refinery Plant Setup 

---

1. Introduction

Setting up a gold refinery plant is a complex and critical project that requires precise planning, technical knowledge, and significant investment. This comprehensive guide is designed for investors, engineers, and gold industry enthusiasts, covering technical, financial, and operational aspects of establishing a gold refinery.

The main objective of this page is to provide a practical and scientific guide to aid investors in decision-making and technical teams in designing and executing the project.

2. Overview

Setting up a gold refinery involves several key stages:

• Plant design and engineering
• Equipment selection and procurement
• Equipment installation and testing
• Operation and quality control

Adherence to international standards and industrial safety regulations is essential at every stage.

3. Multiple Definitions of the Topic

• Technical Definition: A facility that converts low-grade gold concentrates and doré bars into high-purity 99.99% gold bullion.
• Financial/Investment Definition: A project with predictable ROI and profitability from precious metals.
• Operational Definition: Involves equipment, refining methods, skilled workforce, and plant management.

4. Types of Gold Refineries

1. Small-Scale Refinery: Capacity 1–5 tons/month, setup cost $0.5–1.2 million, installation 1–3 months.
2. Medium-Scale Refinery: Capacity 5–20 tons/month, setup cost $2–5 million, installation 3–6 months.
3. Large-Scale Refinery: Capacity >20 tons/month, setup cost $6–15 million, installation 6–12 months.
4. Mini Refinery: Capacity <1 ton/month, modular and portable, setup cost $0.2–0.5 million, installation 1 month.

5. Price Ranges and Methods

Traditional Methods:

• Fire assay and casting
• Cyanide leaching
• Common hydrometallurgical methods

Modern Methods:

• Electrolytic refining
• Green refining

Pricing:

Costs vary depending on capacity, equipment, refining method, and location.

• Small refinery: $0.5–1.2 million
• Medium refinery: $2–5 million
• Large refinery: $6–15 million

6. Refining Methods

• Metallurgical Refining: Metal-based methods for high purity
• Chemical Refining: Use of chemicals to separate impurities
• Green Refining: Environmentally friendly, low-water usage methods

7. Comparison of Refineries

Refinery Type	Capacity (tons/month)	Cost (Million USD)	Installation Time	Suitable For
Mini	<1	0.2–0.5	1 month	Modular and small projects
Small	1–5	0.5–1.2	1–3 months	Small investors
Medium	5–20	2–5	3–6 months	Local companies
Large	>20	6–15	6–12 months	Industrial projects

9. Additional Overview

Depending on project type, budget, and target market, the refinery model selection varies. Careful planning reduces costs and increases efficiency. For example, a medium-scale project typically has better ROI than a small-scale investment but requires a stronger technical and management team.

10. Green Refinery

Using environmentally friendly refining methods reduces energy consumption, chemical waste, and effluent. These methods may have higher initial costs but are cost-effective and sustainable in the long term.

11. Mini, Small, Medium, and Large Refineries

• Mini Refinery: Modular, portable, suitable for very small projects.
• Small Refinery: Ideal for new investors or regional projects.
• Medium and Large Refineries: Suitable for industrial and export-focused projects.
