The main source of information is a data base on corporate control of the production of non-fuel minerals, which has been established by the Raw Materials Group in Sweden. The data base contains data on production, ownership and management of about 1000 companies engaged in the non-fuel minerals industry in the Western world. Reference years arc 1975 and 1984. The data base is updated continuously.
