1. PAINPOINT DRIVEN OPENING

Are you facing escalating operational costs and unpredictable recovery rates in your highvolume gold mining operation? Managing a 500 TPH throughput presents distinct challenges: inconsistent feed material leading to gold loss in tailings, excessive water consumption driving up sourcing and treatment costs, and unscheduled downtime from equipment not engineered for continuous, heavyduty service. These issues directly erode profit margins. How do you ensure neartotal recovery of fine and coarse gold at this scale? Can you reduce water usage by over 50% while maintaining output? Is your washing plant designed for rapid maintenance to maximize uptime? The solution requires a purposebuilt system engineered for efficiency and reliability at an industrial 500 TPH scale.

2. PRODUCT OVERVIEW

This product is a complete, ODMengineered 500 TPH Gold Mining Washing Plant, a modular processing system designed for alluvial and eluvial gold deposits. The plant’s workflow is optimized for highvolume material handling: (1) Primary screening and scrubbing to break down claybound ore, (2) Dense media separation or advanced jigging for coarse gold recovery, (3) Primary sluicing and centrifugal concentration for fine gold capture, (4) Tailings management and water recycling. Its application scope is ideal for largescale openpit mining operations with consistent feed grades. A key limitation is its design for unconsolidated material; it is not suitable for hard rock ores requiring primary crushing.

3. CORE FEATURES

Modular, SkidMounted Design | Technical Basis: Preassembled modules with integrated structural frameworks. | Operational Benefit: Reduces onsite installation time by up to 60%, minimizes civil works, and allows for future plant relocation or reconfiguration. | ROI Impact: Lower capital expenditure on site preparation and faster timetoproduction.
Intelligent Water Recycling System | Technical Basis: Highcapacity thickeners and clarifiers with automated polymer dosing. | Operational Benefit: Recirculates over 90% of process water, reducing fresh water demand to less than 500m³ per day. | ROI Impact: Drastic reduction in water sourcing costs and environmental licensing complexity.
DualStage Coarse Gold Recovery Circuit | Technical Basis: Combination of a static grizzly screen with a highcapacity rotary scrubber followed by a dense media separation (DMS) drum. | Operational Benefit: Achieves over 99% recovery of nugget and coarse gold (+2mm) before the slurry stream, preventing loss and damage in pumps. | ROI Impact: Maximizes revenue capture from the most valuable fraction of the feed material.
PLCControlled Process Automation | Technical Basis: Centralized Programmable Logic Controller with HMI touchscreen monitoring feed rate, water pressure, and density. | Operational Benefit: Operators can optimize performance in realtime, maintain consistent recovery rates across shifts, and receive early fault diagnostics. | ROI Impact: Improved metallurgical stability and reduced risk of human error leading to gold loss.
HeavyDuty AbrasionResistant Linings | Technical Basis: Wear plates manufactured from AR400 steel at all highimpact points within scrubbers, chutes, and launders. | Operational Benefit: Extends component service life by 35x compared to standard mild steel liners under abrasive conditions.| ROI Impact: Lowers longterm operating costs through reduced spare part consumption and maintenance downtime.

6. APPLICATION SCENARIOS

LargeScale Alluvial Mining Operation in West Africa

Challenge: A major operator was experiencing significant fine gold loss (<0.5mm) in tailings from their existing trommelbased plant, with recovery rates plateauing at 89%. Water scarcity also limited operational hours.
Solution: Implementation of this ODM 500 TPH plant featuring enhanced centrifugal concentrators in the fine recovery circuit alongside the full water recycling system.
Results: Overall recovery increased to 95%, capturing an estimated additional $3M USD in annual revenue based on prevailing grades and prices. The operation became selfsufficient for process water.

Established Mine Expanding Processing Capacity

Challenge: An existing mine needed to double throughput without proportionally increasing its environmental footprint or land use permit area.
Solution: Installation of this modular washing plant parallel to the existing circuit due to its compact footprint.
Results: Achieved targeted capacity increase within the same licensed area due to efficient design; shared infrastructure reduced perton capital costs by approximately 30%.
