Sai/t and Chemical Works
94. The subject of salt-making has already been discussed in
paragraph 89, and it was there stated that a small salt industry
now exists at Kharain, between Okad (Augad) and Risut. The
salt pans there tap sea-water from the bay of Risut, and there is
sufficient space in that area to have pans over an area of 3 or 4
square miles, by using the tide and pumping. The conditions for
evaporation are as good as those at Mithapur, if not better, and the
salinity of the sea-water may be assumed as the same. On this
basis it should not be difficult to prepare 250,000 tons of salt annually,
and half this amount easily as a raw material for chemical purposes.
The sea brine concentrated at Mithapur has the following com

Calcium carbonate ..

The Mithapur chemical works are able to deal with 125,000 tons
of sea salt annually, and are capable of producing 150 tons of Soda
Ash daily. In addition, arrangements had been made or were
being made for the outturn of the following products per day .
25 tons of Caustic soda, 7 tons of Chlorine, 2 tons of Magnesium
chloride, 1 ton of Epsom salts, 2| tons of Potassium bromide An image photographically reproduced on to bromide-coated paper. , 2 tons
of Hydrochloric acid, some hydrous potassium-magnesium chlor
(Carnellite) and Magnesia (Magnesium oxide). Thus tbe salt obta n

About this item


This booklet contains a comprehensive geological report compiled by Sir Cyril Sankey Fox for the Omani Government in 1947. The booklet is the first general mineral audit of the southern reaches of Oman, near its border with Yemen, along with a detailed description of the geography. The mineral audit includes descriptions of potential oil deposits. The booklet also contains a map of the Dhufar coast.
