Abstract

Various embodiments provide a leaching solution monitoring module comprising a first leaching solution distribution system interface, a flow meter in fluid communication with the first leaching solution distribution system interface, the flow meter in fluid communication a 3-way pressure regulator, and a second leaching solution distribution system interface in fluid communication with the 3-way pressure regulator.

First claim

What is claimed is:

1. A leaching solution system comprising:
a monitoring module, which includes:
a first leaching solution distribution system interface;
a flow meter in fluid communication with the first leaching solution distribution system interface;
a 3-way pressure regulator comprising a 3-way valve in communication with the flow meter; and
a second leaching solution distribution system interface in fluid communication with the 3-way pressure regulator; and

a leaching solution distribution system connected to the first and second leaching solution distribution system interfaces, thereby allowing the leaching solution to be distributed back to the leaching solution distribution system through the second leaching solution distribution system interface.

2. The leaching solution monitoring module of claim 1 , wherein the flow meter is a differential pressure flow meter.

3. The leaching solution monitoring module of claim 2 , wherein the 3-way pressure regulator is a pressure sustaining valve.

4. The leaching solution monitoring module of claim 3 , wherein the first leaching solution distribution system interface is configured to fluidly couple the leaching solution monitoring module to a leaching solution distribution system.

5. The leaching solution monitoring module of claim 2 , further comprising a first pipe section in fluid communication with the first leaching solution distribution system interface.

6. The leaching solution monitoring module of claim 5 , further comprising a second pipe section in fluid communication with the second leaching solution distribution system interface.

7. The leaching solution monitoring module of claim 1 , wherein the 3-way pressure regulator comprises a pressure adjustment control feature.

8. The leaching solution monitoring module of claim 1 , further comprising a pressure transmitter.

9. The leaching solution monitoring module of claim 8 , wherein the pressure transmitter transmits pressure data to a gateway.

10. The leaching solution monitoring module of claim 7 , wherein the flow meter transmits flow rate data to a gateway.

11. A system comprising:
a plurality of leaching solution monitoring modules, each leaching solution monitoring module comprising:
a first leaching solution distribution system interface;
a flow meter in fluid communication with the first leaching solution distribution system interface;
a 3-way pressure regulator in fluid communication with the flow meter;
a second leaching solution distribution system interface in fluid communication with the 3-way pressure regulator; and
an electronic transmitter for transmitting at least one of flow rate data and pressure data,

leaching solution distribution system connected to the first and second leaching solution distribution system interfaces, thereby allowing the leaching solution to be distributed back to the leaching solution distribution system through the second leaching solution distribution system interface, and
a gateway configured to receive at least one of flow rate data and pressure data from at least one leaching solution monitoring module in the plurality of leaching solution monitoring module.

12. The system of claim 11 , further comprising a data network coupled to the gateway.

13. The system of claim 12 , further comprising a processor configured to communicate with the gateway via the data network.

14. The system of claim 13 , wherein the processor is configured to provide an alert in response to receiving data indicative of at least one of an abnormal flow rate and a low flow rate.

15. The system of claim 12 , wherein the gateway communicates with the at least one leaching solution monitoring module via a Highway Addressable Remote Transducer protocol.

16. The system of claim 11 , wherein the at least one leaching solution monitoring module communicates with at least one other leaching solution monitoring module.

17. The system of claim 16 , wherein the at least one leaching solution monitoring module functions as a repeater with respect to the at least one other leaching solution monitoring module.
