湘黔地区层状沉积岩型钼镍多金属共生矿中硫的碱性高压浸出特性对钼浸出率的影响研究

Impact study about layered sedimentary molybdenum-nickel sulfur polymetallic ore leaching characteristics of the high-pressure alkaline leaching rate of molybdenum in Hunan and Guizhou region

钼镍矿是我国特有的多金属复杂矿种,其中含有的硫等杂质对钼的浸出干扰较大,通过使用碱性高压浸出工艺,发现延长浸出时间可提高矿物中硫的分解率,同时矿物中硫的分解对提高钼的浸出率有明显的影响。

Molybdenum Nickel is a unique complex multi-metal mineral in China, which contains sulfur and other impurities on the molybdenum leaching interferences. By using alkaline pressure leaching process, found that prolonged leaching time can increase the decomposition rate of sulfur minerals, while the decomposition of sulfur minerals to improve the leaching rate of molybdenum has a significant impact.
