The anodic dissolution of ZnS has been studied. The majority of the research was conducted in H₂SO₄. The electrodes were fabricated by hand pressing mixtures of reagent grade ZnS+pitch(5~15%) and sintering at 800℃ n a N_2 atmosphere. The open circuit potentials were mixed potentials resulting from the anodic dissolution of ZnS and the cathodic reduction of S. Current efficiencies and Zn^2+/s ratios were determined at 0.5 and 0.85V vs. Standard Hydrogen Electrode(SHE). The results indicated the occurrance of both chemical and electrochemical dissolution steps. The overall dissolution appears to be mass transfer-limited, probably either by the diffusion of Zn^2+ from the reaction interface, through the reacted layer the bulk solution, or the dissolution of preciptated Zn(OH)_2 in the reacted layer by the diffution of H^+ into the layer.

A relationship between the amount of dietary fat, the concentration of serum lipids and the development of coronary heart disease has been one of the most important medical problems in the recent years. Accumulated data indicate that striking differences exist among different populations in the incidence and severity of coronary heart disease and these differences tend to correlate with dietary factors rather than with racial or other factors. Extensive studies on healthy peoples in various parts of the world lead to the conclusion that the incidence of coronary heart disease is directly to related the average level of serum cholesterol and this cholesterol level is directly related to the percentage of calories provided by fats in the diet, particularly common saturated fats of meats and dairy products. Such a study has never been carried out in Korea and studies in other countries of the Far· East have indicated that their diets are extremely low in the fat content and their serum cholesterol and frequency of the coronary heart disease are also remarkably low. In an attempt to correlate the dietary fat intake, blood lipid level and the Incidence of coronary heart disease in Korean people, the following population groups are selected. 319 farmers, 100 Taegu City people, 50 upper class people, 129 Buddhist Monks, and 90 Korean soldiers attached to the United States Army who have been fed American diet for from 1 to 18 months and 60 American soldiers and officers. On all of those people an analysis of dietary constituents, complete blood lipid analysis including total and free cholesterol, cholesterol ester, total esterified fatty acid . lipid phosphorus, neutral fat. C/P ratio and cholesterol ester/total cholesterol ratio and 12 leads electrocardiogram for evidences of the coronary heart disease were performed and the data thus obtained were analyzed and correlated. The most striking difference in diets of various groups is the fat content. The fat intake of Buddhist Monks and farmers is significantly lower than any other groups and their serum lipid level and the incidence of abnormal electrocardiogram are also lowest in the whole groups. Among Koreans upper class people of Taegu city have the highest fat intake and also the highest serum lipid level and the incidence of abnormal electrocardiogram. The dietary fat intake of Korean is significantly lower than that of American and the serum lipid level and the incidence of coronary heart disease are also significantly lower than American. The results of current study indicate that there is direct correlation between the dietary fat intake, the serum lipid level and the incidence of coronary heart disease and it seems to be reasonable to conclude that among many factors which may affect the remarkably low incidence of the coronary heart disease in Koreans the low dietary fat intake is the most important factor.

Solven extraction is a separation technique in which a solute is transferred from one liquid phase to another immiscible or partially miscible liquid which is in contact with the first phase. In hydrometallurgy, the aqueous phase contains the metal which is to be concentrated into the organic phase. It has been found that Lix 64N are able to separate Cu form Fe, An, Ni, As, etc. ions. The extraction of copper with Lix 64N was carried out at varied pH of aqueous and concentration of organic solvent. The experimental results obtained are summarized as follows ; 1) Loading capacity of Cu^2+ ion increased with raised pH of aqueous but equilibrium extraction was pH 2.0. 2) Loading capacity of Cu^2+ ion lineary increased with increasing concentration of Lix 64N. 3) Continuous solvent extraction circuit was run a stream generated by sulfuric acid leaching solution. the circuit consisted to for extraction stage and two strip stage. It could be seen that was strongly extracted at pH 1.4-1.7 while Fe, Zn, As, and Ni are not extracted.

Because the rolling control technology depends on foreign mill maker, the leaking of rolling control information of POSCO’s characteristic steel is quite serious. And control technicians have problems of applying new control algorithm to real control system due to concerning rolling operation trouble. They also have difficulties of verification of new control logic without test bed instead of real rolling mills. In this paper, we introduced the development of real-time tandem rolling mills simulator for mill controller developers. To give solution to problems mentioned above, the hardware-in-the-loop typed simulator(HILS) including real controller (Siemens PLC) was developed.

The study has been made to determine of impurities effect on copper electrorefining. All deposits were made at the temperature of 50℃ on an aluminium cathode. During the electrorefining of copper, various current densities have been used. The deposits were analyzed by SEM(Scanning Electron Microscope) and determined morphology and crystal orientation by X-ray diffraction. And induction coupled plasma emission spectrophotometer has determined the grade and the impurities of cathoed deposits. The results from this study were summarized follow : 1. Impurities of cathode deposits such as As, Sb were eliminated by chloried ion 2. The higher the chloride ion concentration goes, the higher the current efficiency goes. 3. The higher the current density goes, to the contrary, the lower the grade of cathode copper goes. But at the same current density, the grade of cathode copper increased as the chloried ion concentration goes up. 4. The rough of cathode surface(in the absent of chloride ion at high current density) was improved by addition of chloride ion 5. Crystal orientation of the cathode deposit was effected by chloride ion concentration and current density.

In order to obtain an iron chloride from iron ore, this paper is proposed to the chlorination of iron ore as one of the methods which iron can be obtained. Chlorination processes, obtaining the suitable raw materials for iron smelting, are known as the chlorigizing volatilization pellet process, Ramen-Henderson process and Vuoksenika process, etc. In those processes, most of the impurities contained in the ore are either removed as gaseous material or solution of chlorde. But in this investigation, the recovery of iron chloride from iron ore by extraction is experimented. Accordingly, the effect of grain size, the temperature and time of extraction, and the concentration and volume of solvent of the recovery of iron chloride from ore have been investigated. The results obtained through this experiment are as follows ; 1) ore particle size ; -250 mesh 2) favorable solvent concentration ; 1.5N HCl 3) solvent volume ; 50ml 4) extraction temperature ; 100℃ up 5) suitable extraction time ; 60min
