126 MANUAL FOR SUGAR GROWERS. 



The value of the sugar recovered will be insuffi- 

 cient to make processes of this character remunera- 

 tive in the case of sugar-cane products. 



Beet molasses contains a very large quantity of 

 potash, — on an average four or five per cent. On 

 mixing molasses of this character with sulphate of 

 alumina, a considerable quantity of alum, which is 

 a double sulphate of potash and alumina, crystal- 

 lises out. Processes of this kind have been worked 

 successfully, but are quite inapplicable to cane mo- 

 lasses, as the quantity of potash present is usually 

 only about one-half per cent. 



The problem of finding a remunerative outlet for 

 vacuum-pan molasses is undoubtedly one of the 

 most difficult ones which owners of large factories 

 have to solve, and for them the distillery appears 

 to offer the easiest solution.
