1.3.2. Phosphate
The main producers of phosphate rock and
phosphate fertilizers are the USA, the FSU, China,
Africa and the Middle East. Several of these
countries are
developing countries and the
phosphate industry makes an important
contribution to their economies.
Over the past two decades there has been a
distinct trend towards the processing of
phosphate rock in countries with substantial
natural
resources of this material, especially in
North Africa and the USA, but also in the Middle
East and South and West Africa. There have
been several
plant closures in West Europe,
where phosphoric acid production capacity and
output have fallen by 60% since 1980, for
economic and environmental reasons, particularly
the problem of gypsum disposal.
1.3.3. Potash
Potash is produced in the few countries where
the ores are located. In 1996 Russia
and Belarus
accounted for 23% of the world’s production,
Canada for 35%, West Europe for 23% and
Israel and Jordan for 11%, these few regions thus
accounting for a total of 92% of world
production.
