Bis(methylene phosphonic acid)

Dimethylenephosphonic Acid
This product (cassiterite slime collector) appears as a grayish-white crystalline paste, acidic, low toxicity, with an ionization constant: pK2 = 5.37±0.05~9.41±0.05. It is a diphosphonic amphoteric compound, with an effective content of over 80%. It exhibits good collecting and selective properties for both oxidized tin and sulfide tin. The interaction between it and tin ore involves chemical adsorption, positioning the collector on the cassiterite surface. Its effectiveness is enhanced when used in combination with iso-octanol.
Dosage: 150g~250g/ton of raw ore, iso-octanol 400g~500g/ton of raw ore
Packaging: 50kg/plastic drum, 180kg/plastic drum
