摘要
对于硫化矿，特别是多金属硫化矿，不经焙烧，以含有适量柠檬酸和硅酸钠的氢氧化钠溶液作为水锌矿和菱锌矿的选择溶剂，直接分离测定锌的碳酸盐和硅酸盐，获得了满意的结果。
For sulfide ores especially complex ones, sintering is needless. Sodium hydroxide which contains a certain amounts of citric acid and sodium silicate, as the selective solvent to isolate smithsonite and hydrozincite has been investigated. Carbonate and metasilicate of zinc are determined separately and directly. The method has been used with satisfactory results.
