Flotation Zinc Amine

Design and selection of flotation collectors for zinc

Design and selection of flotation collectors for zinc

Jan 01, 2021 At present, sulfidization-amine method is commonly used in zinc oxide minerals flotation. Sodium sulfide as the sulfidizing reagent is used to increase the negative charges on mineral surface, and amines as collectors are used for zinc recovery through physical adsorption (Fa et al., 2005)

reported that the percentage of zinc recovery was maximized at pH=10 by using stearyl amine as a collector [13 and 21]. The chemical structures of sodium hexametaphosphate (SHMP), stearyl amine (Octadecylamine) and Armac T (Tallow amine acetate) are shown in Fig. Flotation experiments were performed in a 2 Lit Denver cell running 1.

Sulfidization-flotation is the most commonly used method for the recovery of zinc oxidized ores. Usually sodium sulfide is the sulfidizing agent which yields the best performance in most flotation systems [5,6,7]. Salum et al. [8] studied on the role of sodium sulfide in amine flotation of silicate zinc

Flotation of zinc oxide - Afuruika

The amount of zinc oxide used for flotation varies with the type of ore, but the following amount can be used: Floating zinc oxide ore: sodium sulfide 6~12kg/t , primary amine 100~600g/t. Floating mixed zinc ore: sodium sulfide 1~3kg/t , primary amine 50~100g/t. By this method, the general concentrate grade can reach 40~50%, and the recovery
