1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your gold mining project's margins? Commercial operators consistently face critical challenges that directly impact profitability:

High Operational Expenditure: Excessive fuel consumption, frequent component replacement, and high water usage in processing create unsustainable cost structures.
Unplanned Downtime: Equipment failure in remote locations leads to significant production halts, with repair logistics costing thousands per hour in lost recovery.
Low Recovery Rates & Grade Variability: Inefficient separation results in valuable fine gold loss to tailings, while inflexible equipment struggles with changing ore body characteristics.
Labor Intensity & Skill Shortages: Reliance on complex, manuallyadjusted systems increases labor costs and introduces human error, a critical issue in regions with scarce skilled technicians.
Environmental & Regulatory Pressure: Inefficient water recycling and chemical use increase operational costs and regulatory compliance risks.

Is your operation equipped to lower your cost per ton, maximize recovery from complex ores, and ensure reliable uptime in demanding environments? The right equipment portfolio is a strategic investment, not just a capital purchase.

2. PRODUCT OVERVIEW: MODULAR GRAVITY CONCENTRATION & PROCESSING PLANTS

This product line encompasses modular, highcapacity gravity concentration systems designed for alluvial (placer) and hard rock (lode) primary and secondary gold recovery. Engineered for the commercialscale operation, these plants optimize the physical separation of gold from gangue material based on specific gravity differentials.

Operational Workflow:
1. Feed Preparation: Raw material is screened and classified to ensure optimal feed size for downstream concentration.
2. Primary Concentration: HighG force centrifugal concentrators continuously separate heavy minerals (gold) from lighter materials.
3. Middlings & Tailings Handling: Efficient slurry routing ensures maximum recovery while minimizing water consumption.
4. Concentrate Upgrading: The produced heavy mineral concentrate is easily discharged for further upgrading via shaking tables or selective batch concentrators.
5. Water Management: Integrated water recirculation systems are standard, drastically reducing fresh water intake and settling pond requirements.

Application Scope: Ideal for processing alluvial deposits, eluvial materials, and milled hard rock ores where free gold is present. Serves as a primary recovery unit or a scavenger for ball mill/grinding circuit discharges.

Limitations: Not a chemical leaching system. Recovery efficiency is inherently tied to the liberation size of the gold particles. For refractory ores where gold is locked within sulfide minerals, this system functions as a preconcentration stage ahead of leaching circuits.

6. APPLICATION SCENARIOS

Alluvial Placer Mining Operation – West Africa

Challenge:A largescale placer operation was losing significant fine gold (<100 mesh) to tailings using traditional sluices due to fluctuating feed grades and high clay content.Solution:The deployment of two modular gravity plants as primary concentrators after scrubber screens.The automated controls adjusted fluidization parameters as clay content varied throughout the pay streak.Results: Plant recovery increased from an estimated 65% to a measured 92%. The reduced water demand allowed operation during seasonal dry periods.The payback period on capital expenditure was achieved within eight months based on incremental recovered ounces alone.
