1. PAINPOINT DRIVEN OPENING

Managing a gold processing operation requires balancing throughput, recovery rates, and operational costs. Inefficient or unreliable equipment directly impacts your bottom line. Are you facing these persistent challenges?
High Downtime for Maintenance: Frequent component wear and unplanned stops for repairs cripple your production schedule, costing thousands per hour in lost processing capacity.
Suboptimal Recovery Rates: Inefficient separation or leaching processes mean valuable micron gold is lost to tailings, representing a direct revenue leak.
Excessive Operational Costs: High energy consumption for grinding and material handling, coupled with the labor intensity of constant monitoring and adjustment, erodes profit margins.
Environmental & Safety Compliance Risks: Managing cyanide solutions, tailings containment, and volatile material dust requires robust, failsafe equipment designs to mitigate liability.
Scalability Limitations: Inflexible systems that cannot adapt to varying ore grades or throughput targets hinder operational agility and expansion plans.

The right contractmanufactured gold mining equipment is engineered to address these exact issues.

2. PRODUCT OVERVIEW

This product line encompasses heavyduty, precisionengineered gold mining equipment for extraction and beneficiation processes. As a contract manufacturer, we design and fabricate customconfigured systems based on proven principles to meet specific plant requirements.

Typical Operational Workflow:
1. Primary Crushing & Grinding: Customdesigned jaw crushers, cone crushers, and ball/SAG mills reduce runofmine ore to the optimal liberation size.
2. Gravity Concentration & Classification: Cyclones, spirals, or shaking tables separate coarse freemilling gold from gangue material.
3. Leaching & Adsorption (CIL/CIP): Agitated leach tanks with efficient oxygen introduction dissolve gold, followed by adsorption onto activated carbon in a series of tanks.
4. Elution & Electrowinning: Loaded carbon is treated to strip gold into solution, which is then plated onto cathodes via electrowinning cells.
5. Smelting & Tailings Management: Cathode sludge is smelted into doré bars, while inert tailings are safely transported to storage facilities.

Application Scope: Suitable for greenfield projects, plant expansions, and retrofit upgrades for alluvial (placer) and hard rock (lode) deposits.
Key Limitations: Final recovery rates are dependent on ore mineralogy; equipment must be specified based on comprehensive metallurgical test work.

6. APPLICATION SCENARIOS

West African Hard Rock Mine Expansion

Challenge:
An existing operation needed to increase throughput by 40% but had limited footprint space within the existing plant layout. The leaching circuit was identified as the bottleneck.

Solution:
We supplied a compact,
modular CarboninLeach (gold mining equipment) tank train designed as a parallel expansion module. It utilized taller tank designs with our highefficiency agitation system to maximize volume within the constrained area.
