Hill[14] states that possibly 5,000,000 oz. was the total world’s production to June 1917, which he distributes according to the uses made of it as follows: Oz. Chemical and physical apparatus 1,000,000 Electrical devices 250,000 Catalyzing 500,000 Dental uses 1,000,000 Jewellery 1,000,000 Minor uses and hoarded (balance) 1,250,000 It is difficult to obtain exact figures of the annual production of crude platinum. This is particularly so in the case of Russia, where there appears to have been a tendency for private enterprises to keep their published outputs as low as possible, in order to avoid registration. The discrepancy between the official and actual figures of production in Russia is variously estimated at from 20 to 60 per cent.
