In Situ Leaching

Overview

Overview

In-situ leaching or solution mining is a process of recovering minerals such as copper and uranium through boreholes drilled into the formation, without the need for conventional mining. Grundfos can supply submersible and end-suction pumps that ensure the effective pumping of barren or pregnant solutions into the formation and back up to the mineral processing plant.

Leachate solutions vary according to the ore deposit, from freshwater for salt deposits to acid solutions for copper and acid or sodium bicarbonate leachates for uranium. This places heavy demands on pump construction, and Grundfos offers customised pumps for in-situ leaching. Pumps ranges are available built with high-grade steel or, in some cases, titanium, and with a magnetic drive or various kinds of shaft seal solutions. A Grundfos pumping solution can handle very low pH levels and sulphuric acid at low concentrations or high concentrations above 90%.

Our complete range of dosing pumps systems are for large or small volumes and based on different technologies, and Grundfos can also supply electronic and electrochemical accessories for complete control as well as PLC-controlled, fully automatic systems for dry material preparation and reliable dosing.

With possible great fluctuations in demand for performance and multiple pumps installed, adding variable frequency drives will equalize the hydraulic load to the wells, automatically adjusting pump speed to demand. This ensures the optimum delivery of pregnant solution to the formation.

Grundfos motor protection is developed for pumps and not just the motor, and used together with an Interface Module ensures dedicated level control that offers greater protection, because parameters other than electrical conditions in the motor are measured. This makes possible timed stop/start routines that don’t damage the pump or motor and helps avoid sudden outages.

Grundfos pumping solutions let you maximise the use of recycled process water, reducing raw water consumption and minimising treated water discharge. This minimises the impact of operation on the local environment, which is one of the most important goals of today’s modern mining industry.

Correct material selection is the most important method of corrosion prevention, prolonging the life span of pumps systems. Grundfos can supply the specialist expertise to help meet your performance objectives, from the initial identification of needs, to the selection, installation, operation, and maintenance of the pumping solution. Furthermore, Grundfos tailors commissioning agreements and service agreements to your requirements, and spare parts kits and on-site recommended spare parts can also be arranged.
