引言各种硫化鑛物中,闪锌鑛是易于氧化的鑛物之一,当氧化以后,它就相应地变为硫酸锌。如果再与碳酸盐或富含CO_2的地下水相作用,即进一步被交替成菱锌鑛。这一过程已经多次证明属实。菱锌鑛如果与矽酸盐作用,即变为異板鑛。不过異极鑛的成因是否这样,还有待进一步考证。一般而言,氧化锌鑛石中存在最普遍的鑛物是菱锌鑛和異极鑛,而水锌鑛与矽锌鑛甚少。而且脈石为石灰岩或白云化灰岩时,菱锌鑛则佔优势;反之,矽酸盐脈石或石英较多时,異极鑛又佔优势。 Introduction Among various sulfide minerals, sphalerite is one of the easily oxidized minerals, and when oxidized, it turns into zinc sulfate accordingly. If further with carbonates or CO2-rich groundwater phase, that is further replaced by calamine. This process has been proven many times. If the calamine and silicate role, that becomes a different plate mine. However, the cause of hemimorphic ore is the case, yet to be further verified. In general, the most common minerals present in zinc oxide ores are calamine and hemimorphite, with very few hydrometallurgy and ilicide. Moreover, when the gangue is limestone or dolomitic limestone, the calamine is predominant; conversely, when the gangue gangue or quartz is more, the hemimorphite is dominant.
