A recently filed patent (Publication Number: US20230227934A1) describes a leaching solution monitoring system. The system includes a leaching solution distribution system interface that connects to a pipe of the leaching solution distribution system. It also includes a flow meter that is in fluid communication with the distribution system interface and a 3-way pressure regulator with a 3-way valve. An electronic module is configured to receive and transmit data related to the flow rate and pressure of the leaching solution. The leaching solution monitoring module receives the leaching solution from the distribution system interface and allows it to be distributed to the leaching solution distribution system.

The system further includes a processor that receives data from the electronic module. The processor is programmed to provide an alert if it receives data indicating an abnormal flow rate or pressure. The alert can be in the form of an SMS message or an email. The system also includes a data network that is connected to the electronic module.

The flow meter used in the system is a differential pressure flow meter, and it transmits the flow rate and pressure data to the electronic module. The 3-way pressure regulator is a pressure reducing valve and has a pressure adjustment control feature.

In addition to the monitoring system, the patent also describes a method for monitoring a metal recovery system. The method involves passing a leaching solution through the leaching solution distribution system and measuring the flow rate and pressure using the flow meter. The data is then transmitted to the electronic module and processed by the processor. If the processor detects an abnormal flow rate or pressure, it provides an alert. The method also includes adjusting the flow rate and pressure of the leaching solution in response to receiving an alert.

Overall, the patent describes a comprehensive leaching solution monitoring system and method that can detect abnormal flow rates and pressures in real-time, allowing for timely adjustments to ensure efficient operation of the metal recovery system.
