NAX 31

• NAX 31 is Prospec’s Sodium Isopropyl Xanthate (C3 alcohol). NAX31 is a stronger collector than KAX20 and is fairly selective compared to the stronger Potassium Amyl based KAX 51.
• NAX 31 has mineral processing applications in the selective flotation of
  • Low Grade Copper, Copper-Zinc, Copper-Lead-Zinc.
  • Low Grade Refractory Gold (Gold and/or Silver with pyrite and/or arsenopyrite)
  • Activated Zinc
• NAX 31 can float all sulfides but is not recommend for scavenging or high grade sulfides.
• NAX 31 is most commonly used in zinc flotation circuits because it is selective against iron sulfides at high pH (min. 10) while aggressively collecting the copper-activated zinc.
• NAX 31 has also been used for copper and lead flotation.
• NAX 31 can also be used to float pyrite and pyrrhotite if the iron sulfide grade is fairly low and the pH is low.
• Higher grade ore should not use NAX 31 because of the larger retention time required to get desired recovery levels.
• In typical applications, NAX 31 is dissolved in water prior to its introduction to a flotation circuit.
• Finer dosage adjustments can be attained by further diluting the xanthate solution with water.
• NAX 31 easily disperses in most flotation pulps, leading to short conditioning times.
• Stage addition of NAX 31 can improve flotation characteristics where applicable, with typical addition points at the head of a circuit and further downstream.

With a few exceptions, xanthates are sold, packaged and delivered as a dry product requiring solutioning for application in flotation processes.
