Recovery Project to Dead Sea Work

The Dead Sea Works is planning to recover crystallized salt values from the margins of mound of its evaporation ponds.

The material contains significant mineral, but is also mixed with rocks from this ponds construction and miscellaneous debris from past years operation.

We are looking for a process which separates the salt value from the rocks in order to return it to the process and discard the rocks.

Shalom,

Greetings and salutations,

The only successfull way of reclaiming the salts and minerals which

are still adhering to the side walls of the concentration and settling ponds

is to dissolve it with a water stream.

Using irrigation sprinklers such as the rainbird brand will allow you to dissolve the

salts and minerals back into the concentration ponds to reclaim them with out affecting the integrity

of the sidewalls of the concentration ponds.

The sprinkler irrigation water being salt water will dissolve the salts but not scour the pond walls. ■

You can use brine from condenser ponds for dissolving salt deposited on dikes of crystallizers or condensers. There will be expense of having long hoses and pumps. Worthwhile if quatity of salt to be reclaimed is large. ■

These could be floating pumps with hoses for aiming at deposited crystals. ■

the use of brine that is already saturated will not disolve crystilized salt. Leon and I have both work in the salt business for many years. The best way is as Leon says, spray water onto it to disolve and have it go to your evaporation ponds. If it is worth collecting it is worth evaporating again. Anythong else is a waste of money. ■
