摘 要：<正>SCO is a selective dolomite deperessant in theflotation system of collophane and dolomite.Howvever,experi-ments confirmed that reverse phenomenon would occur forsome phosphatic mines.In order to explain the SCO depress-ing mechanism,this paper describes studying results on the ef-fect of dissolved ions on SCO depressing property using ul-traviolet absorption spectra.It is found that the effect of dis-solved ions,especially Ms2+,on the SCO adsorption propertyis strong.When Mg2+ concentration is low,dolomite adsorbsSCO and is depressed.When Mg2+ concentration is more than90g/t in pulp,SCO adsorption capacity on colophane is obvi-ously greater than that on dolomite,which results in the de-pression of collophane.The adsorption results are consistentwith flotation results.
