An improved method based on Neumann way which is used to measure the contact angle has been developed to study more accurately the effect of mineral electropotential on its contact angle.

The temperature effect on precision of electrode potential and its correction;

Compute for solving electrode potential of gauging in oxidimetric and reductometric titration method and measurement of element in the body;

Study on effect of electrode potential on adsorption conformation of L-methionine molecules with surface-enhanced Raman spectroscopy

The experimental results indicate that under certain conditions of pulp potential the surfaces of pyrite are oxidized to form hydrophobic element-S0, as a result the pyrite causes self-induced flotation.

The effects of pH and pulp potential on the depressing activity of new organic d epressant ASC to chalcopyrite and galena have been studied in this paper.

The main points of the new thchnology include adding lime and DDTC into mills at the same time, making use of lime's controlling and stabilizing for the pulp potential as well as selectivity of DDTC on minerals, the lead-zinc-iron sulfide minerals could get effective sparation.
