【摘要】：硫酸鋅和硫酸鉛均是用途廣泛的化工產(chǎn)品。本文以含鋅鉛錫礦粉灰為原料,提出了一條由含鋅鉛錫礦粉灰制備硫酸鋅、硫酸鉛的工藝路線。分別研究了堿溶、酸溶及先堿溶后酸溶的處理方法,重點研究了堿溶的最佳工藝條件,具體為6 mol/L氫氧化鈉體積為20 m L、反應溫度為65℃、反應時間為30 min、沉淀鉛離子的硫酸濃度為3 mol/L,結(jié)果表明:采用堿溶工藝,實現(xiàn)鋅、鋇與錫的有效分離,產(chǎn)品外觀好,品質(zhì)好,成本低廉。該工藝具有工藝簡單、生產(chǎn)成本低、附加值高、三廢少等優(yōu)點,對類似礦粉灰分離及其產(chǎn)品制備具有一定的借鑒作用。
[Abstract]:Zinc sulfate and lead sulfate are widely used chemical products.In this paper, a technological route for the preparation of zinc sulfate and lead sulfate from zinc lead-tin powder ash is proposed.The treatment methods of alkali dissolution, acid dissolution and first alkali dissolution were studied, and the optimum technological conditions of alkali dissolution were studied. The specific conditions were as follows: the volume of sodium hydroxide for 6 mol/L was 20 mL, and the reaction temperature was 65 鈩，
