Investigate how potash is extracted using solution mining.

Indicators for this outcome

(a)	Explore the financial and geological challenges of establishing a solution mine in some deposit locations.
(b)	Summarize the layout (e.g., total mine surface area, size of mining caverns and location of facilities) and processes (e.g., use of cavity control fluid and tracking the stability of the caverns) of operating a solution mine.
(c)	Describe how caverns are closed once solution mining is completed.
(d)	Explore the history of the development of equipment and processes used in solution mining.
(e)	Explore the steps used to extract as much potash as possible from underground.
(f)	Explain how selective horizontal solution mining removes potash deposits in a systematic process in the different halite and sylvinite layers underground.
(g)	Investigate the use of under and above ground water and how it can be reused.
(h)	Explain how brine solution is brought to the surface.
(i)	Assess the environmental impact of different solution mining methods.
(j)	Examine the identity, sources and monitoring of contaminants in brine solutions.
(k)	Describe the advantages and disadvantages (e.g., cost, safety and efficiency) of solution mining.
(l)	Research how technology is integrated into solution mining to improve efficiency and safety.
(m)	Discuss the steps taken to mitigate solution mining risks to keep employees, local communities and ecosystems safe.
