Process method for preparing functional ceramic antibacterial powder from high-silicon tailings
The invention discloses a process method for preparing functional ceramic antibacterial powder from high-silicon tailings. The process method comprises the following steps: carrying out size mixing pretreatment on the high-silicon tailings, carrying out oxidative desulfurization, and preparing the ceramic antibacterial powder. According to the invention, the problems of harmlessness and recycling of the high-silicon tailings are effectively solved, the treatment process of the high-silicon tailings is perfected, and 100% absorption treatment of the high-silicon tailings is realized; according to the method, the high-silicon tailings are subjected to chemical desulfurization treatment, meanwhile, chemical complexing sedimentation of toxic cyanide is achieved, stable blue ferrocyanide solid cyanide is formed, the leaching toxicity of the tailings is lower than 5 mg/L, and the emission standard of common solid waste is met; in addition, based on the fact that the ferricyanide and the copper-silver complex are mixed in the tailings, a good antibacterial effect is shown in the ceramic sintering process, and therefore the obtained powder containing the solid cyanogen has the effect of antibacterial ceramic functional powder, has certain economic value and has sales competitiveness in the market.
本发明公开了一种高硅尾渣制备功能陶瓷抗菌粉体的工艺方法，包括如下步骤：高硅尾渣调浆预处理、氧化脱硫、陶瓷抗菌粉体的制备。本发明有效解决了高硅尾渣无害化和资源化的问题，完善了高硅尾渣处置工艺，实现了高硅尾渣100%消纳处置；通过将高硅尾渣化学法脱硫处理，同时实现了有毒氰化物的化学络合沉降形成稳定的蓝色亚铁氰化铁类固体氰化物，尾渣的浸出毒性低于5mg/L，达到了一般固废的排放标准；另外基于铁氰化物、铜银络合物夹杂在尾渣中经过陶瓷烧结过程将体现出良好的抗菌作用，所以得到的含固体氰粉体具有抗菌陶瓷功能粉体的作用，具有一定的经济价值，在市场上具有销售竞争力。
