Mining

Peripheral dewatering

A series of peripheral deep wells are typically installed around open pit mines to reduce the risk of flooding, which makes them unsafe. Although SPR complete removal of water due to nature is nearly impossible, Grundfos SP and SQ pumps can reduce the water entering mines significantly.

The SP pump resists sand and other abrasive materials and the extra high- grade stainless steel version is suitable for very severe conditions. Fitted with a frequency converter, Grundfos pumps will automatically adjust their speed to the demand.

Underground dewatering

The Grundfos dewatering range is built to last longer than conventional dewatering pumps. This is achieved through extensive use of high-grade materials such as chromium steel, silicon carbide (SiC/SiC), etc.

The Grundfos dewatering range is capable of pump- ing water containing abrasive materials such as sand, clay particles, drill cuttings, and other poten- tially damaging objects that could be found on rock faces in mine shafts, quarries, or gravel pits.

Open pit dewatering

The grey water in open pit mines typically contains abrasives such as stones, clay, sulphur, and the PH value is usually very low. This grey water requires a special pump and the Grundfos DW wastewater pumps is your guarantee for reliable grey water handling. And that's why, you find Grundfos waste- water solutions in the toughest environments – e.g. mines and offshore industries worldwide.

Water treatment

Grundfos has years of experience with water supply and water treatment. The Grundfos pump range fits perfectly with small or medium sized waterworks sites. Our pumps are used worldwide for raw water supply and pressure boosting.

A Grundfos water treatment solution can also include dosing pumps that supply precise amounts of additives to secure the exact water quality required.

Raw water intake

In water supply applications for mining operations and mineral processing, Grundfos submersible pumps guarantee a reliable supply of raw water from lakes or rivers.

The Grundfos range of powerful wastewater pumps are designed for handling drainage, effluent, and sewage from processing, as well as mine camps, these pumps represent the essence of the know-how that Grundfos has built up through more than 25 years in the wastewater business.

The efficient single-channel or SuperVortex impellers provide free passage of large solids. This greatly reduces the risk of clogging and ensures maximum up-time and reduced operating costs. So, once installed these robust pumps will provide years of trouble-free operation at maximum efficiency.

In addition, Grundfos wastewater pumps are easy to install and easy to dismantle for service or inspection. The pumps can be installed submerged on auto-coupling system, as free-standing on ringstand for portable use, or in dry applications.

One of the most important goals of today's modern mining industry is to minimise the impact of operation on the local environment. To achieve this, mines aim to max- imise the use of recycled process water and reduce fresh- water consumption and treated water releases.

Process water

Grundfos offers robust pump solutions, which efficiently recirculate large amounts of water from the processing plant.

The Grundfos process water pumps are designed to handle aggressive water containing chemicals and water with a low PH value.

In-situ process

The in-situ process involves the installation of a series of wells through which a chemical solution is injected into the water, passed through the formation, and pumped back to the surface.

At mineral processing plants, small and medium-sized submersible pumps are used to pump barren or pregnant solutions.

In the mining industry, the creation of dust is an unavoid- able result of operations. However, dust gets into everything, clogging up pipes and mechanical part, creating additional maintenance and repair.

Water spray systems remain the most efficient and cost effective means of dust control for both process and fugitive dust emissions. A Grundfos pump solution can move a large amount of water in a short time, making it possible to use a large nozzle configuration and minimise the need for filtration.

Dust control is an important investment in order to meet strict regulatory demands as well as ensuring safe opera- tions, therefore reliable pump solutions are essential.
