1. PAINPOINT DRIVEN OPENING

Are unreliable equipment testing protocols undermining your gold recovery rates and inflating operational costs? Inconsistent or inaccurate testing of mining equipment can lead to a cascade of expensive problems: suboptimal plant configuration, unplanned downtime for retuning, and the most critical loss of all—valuable gold left in the tailings. Consider these common challenges:
Capital Misallocation: Investing in fullscale equipment based on flawed benchscale test data, resulting in underperforming circuits that require costly retrofits.
Process Inefficiency: Equipment that hasn't been rigorously tested under sitespecific conditions often fails to achieve projected throughput or recovery, creating bottlenecks and reducing overall plant efficiency.
High Operational Risk: Untested or poorly validated machinery leads to more frequent breakdowns, unscheduled maintenance, and safety concerns for your team.
Resource Loss: Even a 12% variance in recovery efficiency, undetected by inferior testing, represents a significant and permanent loss of revenue over the life of a mine.

How can you derisk your capital expenditure and ensure your processing plant operates at its maximum potential from day one? The answer lies in investing in highquality, precisionengineered gold mining equipment testing.

2. PRODUCT OVERVIEW

This content focuses on advanced Gold Mining Equipment Testing systems, specifically modular pilot plants and laboratoryscale test rigs designed for predeployment validation. These systems simulate realworld processing conditions to generate accurate, scalable data for decisionmaking.

Operational Workflow:
1. Feed Characterization: A representative sample of ore is prepared and analyzed to establish a baseline.
2. Parameter Calibration: The testing equipment (e.g., pilot gravity concentrator, leach reactor, or flotation cell) is configured with variables such as feed rate, pulp density, reagent dosage, and retention time.
3. Controlled Test Run: The system processes the ore under tightly monitored conditions, allowing for realtime adjustment and observation.
4. Product Analysis: Concentrates, tails, and intermediates are collected, assayed, and weighed to calculate precise mass balances and recovery curves.
5. Data Reporting & ScaleUp: Comprehensive data is compiled into a report that provides the engineering parameters necessary for designing or optimizing a fullscale production circuit.

Application Scope & Limitations:
Scope: Ideal for greenfield project feasibility studies, brownfield expansion validation, ore variability testing, new technology assessment (e.g., novel gravity concentrators), and optimization of existing circuit parameters (leach kinetics, flotation chemistry).
Limitations: Test results are predictive models; absolute production guarantees require scaleup factors. Systems require skilled technicians for operation and interpretation. They are designed for intermittent batch or continuous pilotscale testing, not for continuous production.
