Abstract:

Slurry walls and methods of using those slurry walls to seal unlined solar ponds are provided. The slurry walls are formed from a mixture comprising clay and cement in water. A trench is keyed into the dike surrounding the solar pond, down to a geotechnically predetermined level. The slurry is deposited into the trench and allowed to harden, after which it is covered with a membrane or other covering. The inventive slurry walls reduce, and preferably prevent, leakage of water from the solar pond.

Abstract:

Metal cyanide suitable for shipment is prepared by introducing an aqueous metal cyanide feed stream to a crystallizer to form a slurry of metal cyanide crystals in their mother liquor. The crystallization step occurs at a temperature between 30. degree. C. and 70. degree. C. , and preferably between 50. degree. C. to about 60. degree. C. The metal cyanide crystals are separated from their mother liquor to form a wet cake product containing from about 75 to 98 wt. % anhydrous metal cyanide crystals, from about 4 to 24 wt. % water, and from about 1 to 5 wt. % of metal hydroxide. The wet cake product is placed into a shipping container for shipment to a desired location. A metal cyanide solution is prepared by dissolving the wet cake product.
