Description:
"The Bureau of Mines has used fourier transform infrared spectroscopy (ft-ir) to study in situ reactions of aqueous solutions of potassium ethylxanthate with cu(II)- and pb(II)-activated sphalerite plates, in which the plates were both the infrared-transparent windows and the reacting surfaces. A copper (I) ethylxanthate formed predominantly with cu(II)- activated sphalerite, regardless of the activation time. The products formed on pb(II)-activated sphalerite depended on the activation times; a short activation time (30 min) yielded a lead ethylxanthate-like product, but a long activation time (90 min) yielded a considerable amount of dixanthogen." - NIOSHTIC-2 NIOSHTIC no. 10005089
