一、试料及设备試验用鉄閃鋅矿精矿的化学成分如下: 显微鏡物相鑑定表明,鋅、铁主要以铁閃鋅矿(Zn,Fe)S形态存在,主要脉石为石英。試驗設备为容量2升、18/8鎳铬合金鋼制高压釜,机械攪拌器由电动机通过皮带輪带动。加热系統为三相电热器,用自偶变压器調节輸入电压以控制温度。氧气由高压气瓶通过減压閥輸入釜內。二、试验结果 First, the sample preparation and equipment used to test the chemical composition of sphalerite concentrate is as follows: Microscopic identification of phase, zinc, iron mainly iron sphalerite (Zn, Fe) S morphology exists, the main gangue quartz. Test equipment for the capacity of 2 liters, 18/8 nickel-chromium alloy steel autoclave, mechanical stirrer by the motor driven by the pulley. Heating system for the three-phase electric heater, with self-transformers to regulate the input voltage to control the temperature. Oxygen from the high-pressure gas cylinder through the pressure relief valve into the kettle. Second, the test results
