Processing/Heap Leaching

Overview

Overview

Heap leaching is an industrial mining process used to extract precious metals such as copper, zinc, cobolt and nickel compounds from ore that has been traditionally mined, crushed and then transported for irrigation on an impermeable leach pad. Grundfos offers transfer pumps, dosing and chemical dosing pumps, and heap leaching, submersible and end-suction pumps covering the entire process.

Leachate solutions vary according to the ore deposit, and heap leaching places heavy demands on pump construction. Grundfos pumps ranges are available in different kinds of high-grade stainless steel or titanium, and with a magnetic drive or various kinds of shaft seal solutions. In addition, Grundfos offers total pumping solutions on any scale, from submersibles to end-suction pumps for aggressive water containing chemicals, such as sulphuric acid and sodium hydroxide, and water with very low pH levels and sulphuric acid at low concentrations or high concentrations above 90%. Solutions for pure sodium hydroxide are also available.

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.

Grundfos pumping solutions let you maximise the use of recycled process water, reducing raw water consumption and minimising treated water discharge. Further heap leaching processing requires large amounts of water, and up to 90% is recirculated following treatment. 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.
