Study on the Collecting Performance of the New-type Collector DKZ-1 to the  Mixed Magnetic Concentrate of Diaojuntai

Abstract

Abstract: Using Decylamine and Chloroacetic Acid as raw materials，a new collector named DKZ-1 was synthesized by synthetic reaction.It was investigated by the open-circuit flotation tests of quartz and mixed magnetic concentrate that when the pH value is 11.5, the amount used of starch, CaCl₂ and DKZ-1 is 800, 1 200 and 600 g/t, the iron concentrate reach to 66.47% and the recovery reach to 82.8%.The results of temperature experiments show that DKZ-1's floatability is best at 25~30 ℃.The adsorption mechanism on quartz by measurement of IR and Zeta potential were investigated.

Key words: DKZ-1 collector, Collecting performance, Action mechanism
