Flotation Performance of Arsonic Acid

It was reported that the collecting capability of p-toluenearsonic acid is best among the arsonic acid collectors. The preparation methods of arsonic acid can be given by the following  

Sodium arsenate is prepared from white arsenic. The reaction is as follows AS2O3 + 2Na2C03 + H2O 2Na2HAsC03 + 2CO2 

As discussed above, amino acids are amphoteric collectors. Various amino acids are used in the flotation of oxide minerals [2, 19, 20]. Take the following reagents for example  

These above reagents can be used to flotate hematite, scheelite, and wolframite. 

Various amino acids can be produced using various raw materials. The sodium aminocarboxylate (Medialan A) and sulfamic acid (Hostapon T) are both synthesized using oleic acid as raw material. The sodium aminocarboxylate (Medialan KA) and sulfamic acid (Hostapon T) are both synthesized using lauric acid as raw material.
