solar evaporation

In 1970, operations were changed to a system that combines solution mining and solar evaporation.

This, he explained, had been one of the solar evaporation ponds for toxic waste.

For inland works, recovery of salt by solar evaporation is a possibility in some locations.

It was once used for the solar evaporation of water, to obtain sodium salts.

Solar Evaporation is the oldest and most energy-efficient method of mineral production.

Some magnesium chloride is made from solar evaporation of seawater.

Approximately 750,000 tonnes of salt are produced annually by means of solar evaporation.

Evaporation can either be solar evaporation or using some heating device.

The production of salt at Guerrero comes from solar evaporation of seawater.

The most important, Salt for table and industrial use has been harvested by solar evaporation from shallow ponds since prehistoric times.

Based on the earth's solar evaporation technology, today's state-of-the-art domestic distillers use recent designs and materials to reach greater efficiency levels.

Grassmere has been divided into solar evaporation ponds.

Many salt producers began to switch operation from boiling their salt to the solar evaporation method by the mid-19th century.

However, a factor that is often overlooked, is the concentration of salts in a pool due to solar evaporation.

Solar evaporation has both a shorter set up time as well as a lower capital expenditure cost, than conventional and solution mining.

Laws were passed to regulate the methods used in the production including boiling and solar evaporation, storage, and sale of the salt.

In deserts, water inflow is low and loss to solar evaporation high, drastically reducing the formation of complete drainage systems.

The technique known as iras Intsik or solar evaporation method was practiced to achieve superior quality of salt.

Solar evaporation ponds at the edges of the lake produce salts and brine (water with high salt quantity).

Onslow is also the site of a 2.5 million capacity solar salt facility, extracted from the sea by solar evaporation.

The sludge is taken from solar evaporation ponds which are used to remove moisture from waste materials, therefore reducing their weight.

Soon after the Union Carbide factory opened in the 1970s, waste was dumped in three solar evaporation ponds.

Options considered included membrane technology, freeze concentration, solar evaporation and various methods of steam assisted evaporation.

The site is basically a Solar Evaporation Ponds System of an area of 112 km2 and processing plants.

Seawater is first concentrated by solar evaporation in shallow pans and then transferred to the hollowed-out halves of palm tree trunks to crystallize.
