equipments for mining gold

Addressing Your Core Challenges in Gold Mining Operations

Gold extraction presents distinct operational hurdles that directly impact your profitability and project viability. Are you facing these critical challenges in your mining operations?

• Declining Ore Grades: Processing more material to recover the same amount of gold places immense strain on your equipment for mining gold, leading to higher energy consumption and wear part costs.
• Unplanned Downtime: Mechanical failures in harsh environments can halt your entire processing circuit, costing thousands per hour in lost production and idle labor.
• High Energy Consumption: Comminution (crushing and grinding) alone can account for over 50% of your site's operating costs, making energy efficiency a primary financial lever.
• Water Management and Environmental Compliance: Inefficient recovery systems lead to gold loss in tailings, while water usage and treatment present ongoing logistical and regulatory challenges.
• Labor Intensity and Operator Safety: Reliance on manual processes for material handling and recovery increases exposure to hazards and limits operational scalability.

How do you select equipment for mining gold that not only addresses these pain points but also delivers a measurable return on investment through enhanced recovery rates and lower total cost of ownership?

Product Overview: Advanced Gravity Concentration & Elution Plant

Our solution for primary and secondary gold recovery is a integrated system centered on high-efficiency centrifugal concentrators paired with an automated elution and electrowinning unit. This system is engineered to maximize yield from both hard rock and alluvial deposits.

Operational Workflow:

1. Primary Classification: Pre-classified ore feed, typically under 6mm from your crushing circuit, is introduced into the system with a controlled water flow.
2. High-G-Force Concentration: The feed slurry passes through our centrifugal concentrator, which uses enhanced gravitational forces to separate gold particles from gangue material.
3. Continuous Concentrate Extraction: An automated scraping system or flush sequence removes the gold-rich concentrate into a secure collection point.
4. Elution & Electrolysis: The concentrate is transferred to the integrated elution plant where gold is desorbed into a solution and then plated onto cathodes in the electrowinning cell.
5. Final Smelting: The loaded cathodes are processed in a furnace to produce doré bars on-site.

Application Scope:
This system is highly effective for free-milling gold and recovering fine gold that is often lost by traditional methods. It serves as a primary concentrator for alluvial operations or a secondary scavenger for hard rock processing plants.

Limitations:
This equipment is not suitable for refractory ores where gold is locked within sulfide minerals, which require pre-oxidation. Optimal performance requires consistent feed grade and particle size distribution.

Application Scenarios

Alluvial Placer Operation in West Africa | Challenge:The operation was losing an estimated 18% of its fine gold fraction (<100 mesh) using traditional sluices, with high water consumption.| Solution:A battery of four G-CON-200E units was installed as the primary recovery method, fed directly from the scrubber screen.| Results:A measured fine gold recovery increase of over $1.2 million annually based on current output. Water recirculation rates improved by over % due to more efficient settling.

Hard Rock Mine Scavenger Duty in Latin America| Challenge:The existing CIP/CIL circuit's tailings assay showed economically significant values of free gold, indicating inefficiency in the primary leaching process.| Solution:A single G-CON-200E unit was installed on the final tailings stream as a scavenger device ahead of the tailings dam.| Results:Tailings grade reduced from an average of g/t Au down consistently below g/t Au. This translated into an additional kilograms of recovered annually with minimal operational disruption.
