Show MANGANESE OUTPUT MAKES LARGE GAINS the shipments of high t grade manganese ore containing 35 per cent and more of manganese in in the united states in 1924 according to preliminary figures issued by the department of the interior and compiled in the ceolo gi cal survey were approximately gross tons in in 1924 valued at compared with gross tons in 1923 valued at this is the first year since 1920 in which the value of high grade ore shipments has passed the million dollar mark notable increases in shipments were made by colorado and montana producers in washington where no production of manganese ore had fiad been made since 1916 a large quantity was produced and shipped from the crescent mine port angeles in 1924 this is the first time that washington has made a notable production of manganese ore it is largely shipments from washington and the increase in those thos e from froin montana from tons in 1923 to about tons in 1924 that has caused the increase in manganese shipments in 1924 it will be noted that montana shipments alone in 1924 were 2500 tons higher than the total for the country in 1923 since september 22 1922 the manganese content not the gross weight of ores imported and apparently the value of the ores has been recorded the estimated manganese content of manganese ore imported is reported by the bureau of foreign and domestic commerce to have been gross tons during the first eleven months of 1924 jan uary to november inclusive compared with gross tons in 1923 assuming an average manganese content of manganese manganese ore imported of approximately 48 50 per cent the imports of ore during these periods were about gross tons for eleven months in 1924 and gross tons for 1923 the value of the imports is given as for the first eleven months of 1924 and for 1923 the shipments of domestic ore containing 10 to 35 per cent of manganese in 1924 dropped to gross tons valued at from tons in 1923 valued at 1 shipments of ore containing 5 to 10 per cent manganese dropped to gross tons in 1924 valued at 1 from tons valued at in 1923 one reason for the large decrease in shipments of ore containing 5 to 10 per cent of manganese is the return to iron ore classification of the ore from the tilden mine of the oliver iron mining company for just one year 1923 the ore from this mine contained sufficient manganese to necessitate its inclusion as a iron ore instead of as an iron ore on the other hand the ottawa mine of the montreal mining company shipped ore again in 1924 which had a high enough manganese content to be included with the ore containing 5 to 10 per cent manganese |
