"The authors have worked out a method for the estimation of tin which consists 

 in precipitating this metal on aluminum dissolving the two metals in hydrochloric 

 acid, and titrating the stannous chloride thus formed by means of iodine or bichro- 

 mate of potassium."

Describes the removal of tin from tin scrap, including tin cans, by the dry chlorine 

 process. 



Estimates 75,000 tons of scrap are treated in Germany each year, and about 25,000 

 tons in the rest of Europe, making 1500 tons of tin and tin-salts. In America 60,000 

 tons, giving 3000 to 3500 tons tin or 3% per cent of the world's product. 



Goldschmidt handles 50,000 tons in Germany.
