All tests were made with flotation complen sulfide concentrate having the following analysis, in wt--pct: 14.57 Cu, 16.52 Zn, 9.52 Pb. The roasting of this concentrate was conducted in a fluidized bed roaster with a bed area of 0.2M~2. Experimental results showed that the minimum superficial gas velocity for normal fluidization was more than 1.1m. s~(-1) at 800℃. Based upon this experimental data the equilibrium gas composition fer oxidizing and sulfatizing roasting of this concentrate was calculated. And the...

The wolframite samples with the differential ratio of Mn to Fe possess flotability varing degrees. But the reason has not been understood. This paper studies floatability, adsorption behavior and electrokinetic phenonmenon of wolframite with different component, and discusses the difference actions of chelating agents with anganous and ferrous ions. The chemisorption of collector on wolframite surfce is closely related to manganous ion. Wolframite of higher ratio of Mn to Fe has better floatability and stronger ability to adsorb collector. Activating action of manganous ion is stronger than ferrous ion.
