目前我国汞的冶炼,大都采用高炉处理块矿,虽能配入部分碎矿,但高炉生产能力降低很多。如果是浮选精矿,则需制成球团后与块矿搭配入炉。处理高炉冶炼过程产出的大量汞炱,至今尚无良好办法。以往渗入石灰进行人工打汞,汞炱打得不干净,被打后的汞炱灰中含有50～60％的汞,还得重新返回高炉处理,影响了汞的直接回收率和总回收率,增加了材料、燃料的消耗,而且劳动强度大,卫生条件不好。用浸出一电解流程处理浮选汞精矿的办法,因过滤、电耗等
At present, China smelting of mercury, most of the use of blast furnace processing lump ore, although part of the crushed ore, but the blast furnace capacity to reduce a lot. If it is flotation concentrate, it needs to be made into pellets and lump ore into the furnace. There is no good way to deal with the large amount of mercury 高 produced in the blast furnace smelting process. In the past, artificial mercury was infiltrated into the lime and the mercury 炱 was not clean enough. After being beaten, mercury 炱 ash contained 50-60% mercury and had to be returned to the blast furnace for treatment, affecting the direct mercury recovery rate and the total recovery rate. Increased material, fuel consumption, but also labor-intensive, poor sanitation. Leaching an electrolytic process flotation of mercury concentrate approach, due to filtration, power consumption and so on
