Among them is the Namsi Saltern that has tapped over 5o ultra-saline water deposits and carried out boring for them in an effective way.

It has drawn tens of thousands cubic meters of underground ultra-saline water from those deposits, so as to boost the production by three times.

And it leveled and hardened tens of hectares of evaporating and crystallization grounds and cleaned out thousands meters-long waterway.

It has also been pushed forward to increase the proportion of mechanization in salt-making.
