Nanometer zinc oxide powder has been prepared by direct precipitation method using zinc electrolyte as raw material from a factory in Xiangxi and Na2CO3 as precipitator.

The method had been successfully applied to the determination of trace antimony in zinc electrolyte with satisfactory results.

Practice of electric power peak-load shifting transmission system in zinc electrolysis;

According to the production practice of Zinc electrolysis,the paper has introduced that the link-up of the big area female Copper line is one of the main factors influencing the direct current consumption.

According to the production practice of Zinc electrolysis in Zhuzhou Smelter,this paper introduced in detail the factors affecting current drain,and put forward the main methods of energy saving in Zinc electrolysis.

A multi-objective optimal model for time-sharing power supply dispatching of electrolytic zinc is established.

Directed against the principle of count by time-sharing and based on the parameter model of electrolytic zinc process,an optimization model of power supply for electrolytic zinc is established in this paper.

This paper analysis the electrolytic zinc power supply process in a smelting plant,shows the structure of the long distance monitor and control system,proposes a kind of real time hierarchical control net.

This paper researchs the influnte of Mn~2+ concentration in the electrolyte of zinc electrolysis on the structure and the formation mechanism of MnO_2 deposit on the anode.
