1. PAINPOINT DRIVEN OPENING

Are you managing gold recovery operations burdened by inconsistent yields, high operational complexity, and escalating costs? Standard, offtheshelf equipment often fails to address the specific mineralogy of your deposit, leading to significant gold loss to tailings. Plant managers face daily challenges with low throughput rates due to inefficient separation, excessive downtime for maintenance and adjustments, and the high operating costs of water and reagent consumption. Engineering contractors struggle with complex, multistage installations that delay project timelines and inflate capital budgets.

What if your gold recovery plant could achieve higher concentrate grades with a single, optimized unit? How would a 1520% reduction in operational downtime impact your annual output? Is there a solution that offers both robust construction for harsh environments and precise control for maximum recovery? These are the operational questions a purposebuilt Custom Gold Mining Equipment ODM manufacturer is designed to answer.

2. PRODUCT OVERVIEW

This content outlines our service as an ODM (Original Design Manufacturer) for Custom Gold Mining Equipment. We engineer and fabricate mineral processing machinery tailored to the specific characteristics of your ore body, plant layout, and production targets.

Operational Workflow:
1. Consultation & Ore Analysis: Our process begins with a detailed review of your ore assay data, particle size distribution (PSD), and gold liberation characteristics.
2. Conceptual Design: Engineers develop equipment specifications—such as a custom centrifugal concentrator bowl profile, jig pulse sequence, or scrubber drum configuration—to optimize recovery for your material.
3. Detailed Engineering & Fabrication: All components are designed for dutyspecific performance and fabricated from specified materials.
4. Factory Acceptance Testing (FAT): Equipment is tested under simulated conditions to verify performance metrics before shipment.
5. Deployment & Optimization: Onsite support ensures the custom unit integrates effectively into your existing circuit.

Application Scope: Tailored solutions for gravity separation (centrifugal concentrators, shaking tables, jigs), crushing/scrubbing circuits, and specialized leaching/adsorption systems for unique ore types.
Limitations: Custom solutions require detailed upfront ore data and engineering engagement; they are not suitable for operations seeking immediate, standard equipment delivery without a design phase.
