Abstract
A device and method for recovering a metal-bearing solution from a leaching system is provided. The method includes collecting, using the collector of a solution sampling device, a metal-bearing solution from a leaching system, storing, using the storage reservoir of the solution sampling device, the metal-bearing solution, pressurizing, using an air pressure line of the solution sampling device, the storage reservoir, and discharging, using a solution sampling line of the solution sampling device, the metal-bearing solution from the storage reservoir.
Claims20
A device for sampling a metal-bearing solution comprising:
- a collector;
- a grating removably coupled to the collector;
- a storage reservoir coupled to the collector;
- a check valve coupled to the collector and configured to form a fluid interface between the collector and the storage reservoir, wherein the check valve permits solution flow through the check valve from the collector into the storage reservoir when the check valve is in an open position;
- an air pressure line configured to pass through the collector and rest in the storage reservoir;
- and
- a solution sampling line configured to pass through the collector and rest in the reservoir.
A system for sampling a metal-bearing solution comprising:
- a leaching system;
- and
- a plurality of solution sampling devices, wherein each solution sampling device comprises:
- a collector;
- a grating removably coupled to the collector;
- a storage reservoir coupled to the collector;
- a check valve coupled to the collector and configured to form a fluid interface between the collector and the storage reservoir, wherein the check valve permits solution flow through the check valve from the collector into the storage reservoir when the check valve is in an open position;
- an air pressure line configured to pass through the collector and rest in the reservoir;
- and
- a solution sampling line configured to pass through the collector and rest in the reservoir;
- wherein the plurality of solution sampling devices are configured to discharge a metal-bearing solution in response to a pressurization of the device.
