An oxidized zinc ore from Inner Mongolia was found to be very difficult to treat due to its features of high oxidation rate,heavy weathering and the intimate association of hemimorphite and limonite.

内蒙某氧化锌矿石氧化率高,风化严重,异极矿和褐铁矿系紧且复,个难选的氧化锌矿。

Under supergene process influencing, kaolinites invered dickites, siderite were been ferritization, part of carbonate mineral have been dissoluted producing calcite.
