Abstract: Leaching effect on arsenic and antimony in soil of antimony ore area in Guizhou Province,China by tartaric and malic acid were studied. Experimental results show that the leaching efficiency of soil arsenic and antimony by tartaric and malic acid increases significantly with increasing of concentrations of acids and increases gradually with increasing leaching time. The best leaching efficiency reaches after 8 h of leaching time. Experimental results also show that the leaching effect of tartaric and malic acid gradually decreases with increasing pH from 3 to 12.
