Tests were performed in a flow loop containing 10, 20 or 30 wt.% particle concentration and saturated potash brine at a slurry flow velocity of 4 m/s. ... there is an increased pressure on potash mining and processing facilities to meet the increasing global need for fertilizer. About 95% of global potash production is used as fertilizer [1].

Since river organisms are adapted to freshwater, the increase in the salt concentration caused by potash mining wastes has the potential to significantly alter the river ecosystem (Cañedo-Argüelles et al., 2013). Studies on the River Werra (Germany), which was heavily impacted by potash mining, showed a recovery in biological …

Potash mining is the process of extracting potassium-rich salts from underground ore deposits or brine pools. The extracted potash is used primarily as a fertilizer in agriculture, but also has other industrial applications. There are two main methods used for potash mining: conventional mining and solution mining.

For potash solution mining, when the pond water is re-injected into the deep salt-bearing formation to extract potash, various microorganisms feed off the organic matter.
