Summary
[edit]DescriptionSolar salt. New Zealand. (8107348401).jpg |
Until the 1940s the lake bed at Lake Grassmere, Marlborough, was a mud bath in winter and a dustbowl in summer, with the occasional natural deposit of salt. The salt-making industry has arisen since then. In 2005 Lake Grassmere provided about half of New Zealand’s salt requirements. In addition to low rainfall (about 585 millimetres per year), Lake Grassmere is perfectly suited to solar salt production. The large area of flat land that makes up the lake bed is near the sea so it can draw in salt water, and away from large rivers. High evaporation from sun and wind occurs during summer, and the site has ready access to both sea and rail transport. The salt is produced from sea water by evaporation. Sea water is pumped through a series of large ponds, which concentrate the water, into a series of smaller ponds, which then crystallise the minerals out of water. |
