Targeting Plant Managers, Procurement Specialists, and Engineering Contractors in Precious Metals Processing

1. Addressing Critical Operational Challenges in Gold Ore Processing

Your operation’s profitability hinges on maximizing recovery from complex ore bodies while controlling escalating operational costs. For professionals managing what industries used gold ore, the challenges are specific and costly:

• Declining Ore Grades: Processing lower-grade deposits requires higher throughput volumes to maintain yield, straining comminution and separation circuits, and increasing energy costs per ounce.
• Complex Mineralogy: Refractory ores, sulfide encapsulation, and preg-robbing carbonaceous materials lock gold away, leading to direct recovery losses that can exceed 20-30% in conventional cyanidation circuits.
• Environmental & Regulatory Pressure: Managing cyanide consumption, tailings liability, and water usage is no longer just an operational cost—it's a critical license-to-operate issue with significant capital implications.
• Energy Intensity: Comminution (crushing and grinding) alone can account for over 50% of a site's energy bill. Inefficient liberation directly impacts downstream recovery efficiency.

Are your current processes fully optimized for the specific mineralogy you're feeding? Is your recovery circuit capturing all economically liberatable gold, or are you leaving value in the tailings?

2. Product Overview: Advanced Agitated Cyanide Leach Reactor Systems

For operations focused on what industries used gold ore, our engineered leach reactor systems are designed to optimize the dissolution of liberated gold into cyanide solution. This technology is central to modern hydrometallurgical extraction.

Operational Workflow:

1. Feed Preparation: Ground ore slurry (typically -200 mesh) is preconditioned with lime for pH control.
2. Optimized Leaching: Slurry enters a series of mechanically agitated reactors where dissolved oxygen (DO) and cyanide concentration are precisely managed.
3. Solid-Liquid Separation: Leached slurry reports to thickening or filtration for advance to gold recovery (e.g., carbon adsorption, Merrill-Crowe).

Application Scope & Limitations:

• Scope: Ideal for free-milling oxide and sulfide ores where gold is sufficiently liberated after grinding. Effective within standard cyanidation chemistry parameters.
• Limitations: Not a direct solution for fully refractory ores requiring pre-oxidation (e.g., pressure oxidation, bio-oxidation). Performance is contingent on proper upstream comminution.
