Abstract

A general reviev of world-wide sulfur supply and demand gives an account of a steadily groing production of sulfur namely, from 8620,7 th. tons in 1938 /China and U.S.S.R. excluded/ and 11244,0 th. t. in 1950 /China and U.S.S.R. excluded/ up to 24924 th. t. in 1962. Asimilar development occurs in sulfur demand, a well known raw material of many various ways of apllication, particularly in industrial countries. Not only its quantitative production based on different sulfur bearing sources was involved in that development but also the composition of the raw material and its space distribution structure. World production of pure sulfur grew up from 3,364 th. t. /39,02/ in 1938 to 6016 th. t. /53,51%/ in 1950 and as much as 13,564 th. t. /54,42%/ in 1962, and at the same time of other raw material origin /14,32%/ in 1962, others from gas and sulfuric metals ore/ also from pyrites, although their part in world production declined from 50,78% in 1938 /4376,9 th. ton/ to 31,26% in 1962 /7791 th. t./. Space distribution change in sulfur production were particularly notable in North America in the first place, and also in Eurasia where new sulfur production centres have lately sprung up and former ones developed in USA, Canada, Mexico, France, Poland, China and in the Soviet Union especially. Sulfur industry space distribution cannot be expected to undergo any assential changes in the near future, neither may there occur any serious alterations of sulfur export and import directions, while quantative changes of sulfur production, judging by aconsiderable growth of sulfur production in capitalistic countries, ought to be foreseen.
