Show THE NATIONS JUNK PILE CONTENTS SECONDARY METALS production IN 1922 the total amount of secondary metals of certain classes recovered in 1922 amounted to short tons most of which was recovered as a pure metal and the remainder in alloys and salts there was a large increase in all classes of metals and alloys recovered from crosses dr scrap etc in 1922 owing to increased operations at manufacturing plants and to the large accumulations of scrap metals from former years the imports of scrap brass and coper were also much larger than normal the following statistics which are issued by the department part ment of the interior were compiled by J P dunlop of the geological survey they are advance estimates but will closely approximate the final figures secondary copper recovered lit in 1922 short tons copper as metal copper in alloys other than brass copper from new scrap copper from old scrap brass scrap melted re new clean scrap old scrap copper content of brass scrap averaging 70 per cent copper new scrap old scrap tot total al se second condry ry copper from new scrap F from rom old brass scrap imported scrap copper imported bras scrap exported scrap copper exported 1400 Second secondary nry lend recovered in 1923 1922 short tons secondary lead recovered by smelters shelters sm elters that treat mainly secondary ores i lead mcw recovered rd i by Y shelters smelters sm i elters that 1 treat wt only ly i scrap and crosses secondary lead recovered in res melted alloys lead content of lead scrap treated at regular lead smelters shelters sm elters lead content of crosses and scrap alloys treated at secondary smelters shelters sm elters total lead in alloys total secondary lead recovered refined primary lead produced in the united states from domestic ores from foreign ores and base bullion lead content of oc antini onial lead ores aie treated abed a at i regular smelters shelters sm elters from foreign and domestic sources secondary zinc recovered in 1922 secondary zinc recovered by secondary zinc recovered by sweating re melting etc total zinc recovered unalloyed zinc recovered in alloys other than brass zinc recovered in brass estimated dust made bom zinc dross cinc dross used for zinc dust zinc dross exported secondary antimony recovered nearly all in alloys 7 antimony produced from domestic ores none antimony content of anti monin lead ores from domestic and foreign sources treated at regular lead smelters shelters sm elters 1441 antimony imported as metal in ore or as oxide of salts Second secondary nry tin recovered in 1022 1922 tin recovered as pig tin tin recovered in alloys and chemical compounds clean tin scrap treated long dong tons old ton coated containers treated long tons metallic tin ti tinning de plants pounds tin content of tin tetrachloride tin and tin oxide made at de tinning plants pounds total ti recovered at df dp tinning blants tin tin and tin oxide made at de tinning plants average quality of tin recovered per long ton of old od till ti cot coifed d containers 2204 average quantity of tin till recovered per long ton of clean tin plate scrap secondary recovered in 1922 secondary aluminum recovered aluminum recovered in alloys mainly no 12 9 secondary nickel recovered in 1922 nickel recovered ns as metal 4 nickel recovered in nonferrous non ferrous alloys alloys and nd S alts 1408 1512 |
