Salinor's solar salt units are located in the northeast region of Brazil, in the State of Rio Grande do Norte which is responsible for 90% of the total Brazilian production of solar salt. This area is particularly favored in practically all factors necessary for the successful commercial production of solar salt. It has a high annual evaporation rate of 2.800 mm per year, with comparatively low rainfall of 500 mm per year, with major concentration occurring in the period from March to May. It also has impermmeable soil, high temperatures and regular trade winds at an average speed of 25 km per hour.

Salinor's solar salt units produce salt by means of a continuous process of evaporation of sea water, which is pumped into a series of concentration ponds, where sea water gradually increases its ratio of sodium chloride, reaching the last pond as saturated brine and ready to feed the crystallizing or harvesting ponds where salt is deposited from June to January of every year.

Salt produced at these Salinas is mechanically harvested, washed with saturated brine and stocked in the storage areas.

Nowadays, Salinor has a total evaporation area of 9,000 hectares and a crystallizing area of more than 800 hectares, which allows a production of more than 2 million metric tons of coarse grade solar salt per year.
