Abstract: A pond for cooling and/or recovering salt from a hot aqueous solution of a salt such as potassium chloride produced by solution mining. The pond comprises a plurality of channels arranged side-by-side, each of the channels being defined by a plurality of sides. An inlet is provided in a side of a channel for receiving the aqueous solution, and an outlet is provided in a side of another one of the channels for discharging the aqueous solution. The pond has at least one dike separating the channels from one another. A gap is formed in each dike to permit the aqueous solution to flow between the channels, the gap having a length which is about 10 to about 40 percent of the length of the sides of the channels. Salt is crystallized and the solution is cooled as it passes through the channels of the pond.
