1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your gold mining project's margins? The efficiency of your recovery operation hinges on the reliability and precision of your core extraction and processing equipment. Common challenges with suboptimal machinery include:

High Operational Expenditure: Inefficient equipment consumes excessive power and water, while poor recovery rates leave valuable micron gold in the tailings, directly impacting revenue.
Excessive Maintenance Downtime: Frequent mechanical failures in harsh mining environments lead to unscheduled stoppages, halting entire processing lines and delaying production targets.
Inconsistent Recovery Performance: Variable feed grades and particle sizes can overwhelm static systems, causing gold losses and requiring constant manual adjustment from your plant operators.
High Chemical Consumption: Nonoptimized systems often overconsume reagents like cyanide or flotation chemicals, unnecessarily increasing both cost and environmental management complexity.

Is your current setup delivering the consistent tonnageperhour and recovery percentage your feasibility study promised? The selection of engineered gold mining equipment is a primary determinant of your site's longterm profitability.

2. PRODUCT OVERVIEW: MODULAR GRAVITY CONCENTRATION & CYANIDATION PLANT

This product line encompasses a suite of integrated gold mining equipment designed for primary and secondary alluvial/hard rock operations. The system focuses on maximizing recovery rate (%), minimizing operational cost ($/ton), and ensuring operational simplicity.

Operational Workflow:
1. Primary Crushing & Milling: Feed material is reduced to a target liberation size via jaw crushers and ball mills.
2. Gravity PreConcentration: A centrifugal concentrator (e.g., Knelson or Falcon type) recovers coarse free gold immediately, reducing downstream load.
3. Leaching & Adsorption: The gravity tailings report to an agitated leach tank circuit where gold is dissolved. The pregnant solution then flows through a series of carbon adsorption columns (CIP/CIL).
4. Electrowinning & Smelting: Loaded carbon is treated in an elution column; the highgrade eluate is processed in an electrowinning cell to produce cathode sludge, which is then smelted into doré bars.

Application Scope & Limitations:
Scope: Ideal for mediumscale operations processing 50 500 tons per day (TPD). Effective for both freemilling ores and some refractory ores with pretreatment. Suitable for fixed plant or modular deployment.
Limitations: Not a standalone solution for highly refractory ores requiring biooxidation or pressure oxidation. Feed particle size must be controlled within design parameters for optimal recovery.
