【摘要】 硫化矿物电极电位不是可逆电极的平衡电位,而是不可逆电极的稳定电位。溶液的性质、浓度、pH值对硫化矿物稳定电位值起主要影响作用:溶液的氧化性愈强,稳定电位愈高;氧化性溶液浓度下降,稳定电位也随之下降,但对还原性溶液则相反;稳定电位随溶液pH值升高而降低。深部硫化矿体电化学分散作用主要是矿物电化学溶解和离子长距离搬运,而矿物的稳定电位是决定这些作用的主要因素之一。更多还原

【Abstract】 The electrode potential of sulfide minerals is not an equilibrium poten-tial of a reversible electrode, but a steady potential of a nonreversible elec-trode. The property, concentration and pH value of the related soltttionhave a great influence upon the steady potential value of sulfide minerals.The higher oxidizing ability of the solution, the higher the steady poten-tial value; the steady potential is lowered along with the lowering of theconcentration of oxidizing solution; but for reducing solution, the steadypotential value is inversely proportional to pH value of the solution. Theelectrochemical dispersions of the deep-lying sulfide orebody are consideredmainly as the electrochemical dissolution of the minerals and long-distancetransportation of the ions, while the steady potential of the minerals is oneof the major factors determining those actions.更多还原
