A new type of flotation reagents, phenoxy-containing (acetic acid compounds), were prepared by treating phenol or a polyphenol, such as dihydroxybenzene and v-trihydroxybenzene, with chloroacetic acid in an alkali solution Controlling the reaction pH value and developing a new self-sealing method brought about a good synthesizing result with high yield and selectivity. It has been shown that the synthesized chems., especially the product of pyrogallol and gallic acid reacting with chloride acetic acid, act as effective depressants in the flotation of calcite. When sodium oleate with 1 x 10-4 mol/L is used as a collector, calcite can be completely depressed when the concentration of two chems. is 4 x 10-5 mol/L and 5 x 10-5 mol/L at pH value 8.78 and 8.47, resp. The electronegativity of group, reagent specific exponent and HLB are discussed, which have explained the depressing mechanism and structure-property relationship of the synthesized chems.
