【摘要】：硫及其硫酸鹽對鋁土礦的溶出工藝存在不利的影響,針對河南某高硫鋁土礦進(jìn)行反浮選脫硫試驗(yàn),為下一步氧化鋁的生產(chǎn)提供合格產(chǎn)品。以碳酸鈉為p H值調(diào)整劑,新型藥劑SNS為抑制劑,硫酸銅為活化劑,丁基黃藥為捕收劑,通過單因素條件試驗(yàn),一次選礦取得了硫精礦中硫品位為5.5%,硫精礦產(chǎn)率為18.69%,脫硫率為83.52%,鋁精礦含硫量為0.25%的試驗(yàn)指標(biāo)。當(dāng)原礦硫品位為1.53%時,工業(yè)生產(chǎn)調(diào)試取得了脫硫率84.98%,硫精礦硫品位30.39%的指標(biāo)。實(shí)現(xiàn)了無尾礦生產(chǎn),對于資源綜合利用和保護(hù)環(huán)境具有重要的意義。
[Abstract]:Sulfur and its sulfate have adverse effects on the leaching process of bauxite. In order to provide qualified products for the production of alumina in the next step, a desulphurization test on reverse flotation of a high sulfur bauxite in Henan Province has been carried out. Sodium carbonate was used as pH adjuster, SNS as inhibitor, copper sulfate as activator, Ding Ji xanthate as collector. The sulfur grade of sulfur concentrate is 5.5, the yield of sulfur concentrate is 18.69, the desulphurization rate is 83.52, and the sulfur content of aluminum concentrate is 0.25%. When the sulfur grade of raw ore is 1.53, the index of desulphurization rate 84.98% and sulfur grade 30.39% of sulfur concentrate is obtained for industrial production adjustment. The realization of tailings-free production is of great significance for the comprehensive utilization of resources and the protection of the environment.
