Solution mining through injection wells is an option that can minimize the environmental footprint and potential impact to surface water compared to more traditional mining processes. To prevent contamination of ground water (which in many cases is a USDW) by Class III wells, more fluid is extracted than is injected in solution mining processes.

Whether for use in an underground mine or during dredging operations, RIP pumps combine sturdiness and reliability for efficient cleaning of sumps. The wear parts are made of high chromium for improved durability and extended service life. They are designed with a wider space between the impeller vanes for easier movement of water with a high concentration of solids.

In mining operations, slurry pumps are used to transport the target minerals and overburden to plants which use a system of wet separation. After crushing and screening, the mineral is usually milled before being transported for further separation. This process requires a large volume of slurry to be transported across often long distances.
