Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In metal recovery systems, particulates and organic contaminants ('crud') can obstruct leaching solution distribution systems, leading to flow rate and pressure issues that hinder metal value recovery processes.
Innovation Solution
A leaching solution monitoring system comprising a flow meter, pressure regulator, and electronic transmitter, which detects flow rate and pressure changes across the distribution system, allowing for real-time monitoring and centralized data transmission to identify and address plugging issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If leaching solution flows through distribution pipes with nozzles, then metal bearing materials can be leached effectively, but crud accumulates and obstructs the nozzles over time
Solution Approach 1:
The system performs preliminary detection of flow rate and pressure parameters before complete nozzle plugging occurs. By monitoring these parameters continuously, the system can identify trends indicating crud accumulation and trigger maintenance actions before the nozzles become fully obstructed, thereby maintaining productivity while preventing reliability failures.
Solution Approach 2:
The monitoring system provides continuous feedback on flow rate and pressure conditions in the leaching solution distribution system. This feedback enables operators to adjust operating parameters or initiate cleaning procedures based on actual system conditions, resolving the contradiction by maintaining nozzle performance through active control rather than passive operation.
2Reliability
If crud accumulates in the leaching solution distribution system, then nozzles become obstructed, but implementing continuous monitoring increases system complexity
Solution Approach 1:
The monitoring module serves multiple functions simultaneously: it measures flow rate, measures pressure, transmits data to centralized systems, and provides alerts for maintenance. By consolidating these functions into a single integrated module, the system achieves reliable nozzle monitoring without proportionally increasing overall system complexity.
Solution Approach 2:
The monitoring system is designed to operate autonomously, continuously measuring parameters and transmitting data without requiring constant human intervention. The system serves itself by automatically detecting flow and pressure conditions and communicating status to centralized control, reducing the operational complexity burden despite the added hardware.
3Productivity
If flow rate is increased to maintain productivity, then metal recovery efficiency improves, but pressure increases and exacerbates plugging issues
Solution Approach 1:
The system uses feedback from simultaneous flow rate and pressure measurements to detect the relationship between these parameters. When flow rate increases cause pressure to rise to problematic levels, the feedback mechanism enables operators to adjust parameters or initiate corrective actions to prevent plugging, thereby maintaining productivity without exceeding pressure thresholds.
Solution Approach 2:
The monitoring system enables dynamic adjustment of operating conditions based on real-time measurements. Rather than operating at fixed flow rates, the system can dynamically optimize flow and pressure parameters within safe operating envelopes, maintaining productivity while adapting to changing system conditions such as gradual nozzle clogging or variations in leaching material properties.
