This document aims to assist in using the Organic Dynamic Volumetric Inventory Virtual Sensor created to meet the Process Metallurgists' needs when using the Solvent Extraction App. It provides Process Metallurgists with essential information to efficiently manage and optimize the Solvent Extraction circuit organic component.
To access the Solvent Extraction Circuit Organic Dynamic Volumetric Inventory Virtual Sensor, you need to first login to the IntelliSense.io Solvent Extraction App and click on the "Dashboard" icon on the left side in the Solvent Extraction App. A drop down box will appear with a list consisting of available dashboards, and you then select "SX Dashboard" and in this dashboard you will find the the Solvent Extraction Circuit Organic Dynamic Volumetric Inventory Virtual Sensor presented in a time graph titled "Total Organic Volume".
Figure 1 shows the Organic Inventory Dynamic Volume Virtual Sensor Monitoring on the SX Dashboard.
The Loaded Organic Dynamic Volumetric Inventory in any solvent extraction circuit is usually calculated periodically by metallurgists in order to assess organic consumption rates and to assess and forecast fresh organic component (diluent and organic extractant) top-up.
Here's how this virtual sensor helps solve issues:
Identifying Variations: By continuously tracking the Loaded Organic Dynamic Volumetric Inventory, As a metallurgist you can identify any variations in the volume of the loaded organic phase. Significant deviations from the expected volume can indicate issues within the extraction process.
Detecting Loss of Organic Phase: If there is an unintended loss of the loaded organic phase at any stage of the process, it will be immediately evident from the inventory tracking. This could be due to leaks, spills, or other operational problems that may occur during handling and transfer.
Pinpointing Inefficiencies: The data from the inventory tracking can help pinpoint specific stages or equipment where inefficiencies are occurring. For example, if the decrease in extraction efficiency is linked to reduced copper loading in the organic phase, the virtual sensor can help identify the stage where this reduction is happening.
Adjusting Operating Parameters: Armed with real-time information on the Loaded Organic Dynamic Volumetric Inventory, the operators can make timely adjustments to flow rates, solvent composition, and other process parameters to optimize metal extraction efficiency and maintain consistent performance.
Preventive Maintenance: The virtual sensor provides regular monitoring of the inventory which allows for the metallurgist to schedule preventive maintenance, ensuring that equipment is functioning correctly and reducing the likelihood of unexpected downtime.
