Surface working method for mineral casting

The invention provides a surface working method for a mineral casting and provides a method for the mineral casting, which needs no subsequent process after direct demolding. Therefore, various shortcomings in the prior art are overcome. The surface of the mineral casting, processed by the method, is smooth and does not need any treatment. Thus, such procedures as polishing, cleaning and painting,required to be performed on the surface of the de-molded mineral casting in the prior art, are avoided, and environmental pollution and harms to an operator, caused by dust and harmful substances, are prevented. 一种矿物铸件表面加工方法，为矿物铸件提供一种直接脱模后不需要后续加工的方法，从而解决现有技术的多种不足。用本发明提供的方法处理的矿物铸件表面，使矿物铸件脱模后表面光洁，不需要任何处理，从而避免了现有技术需要对脱模后的矿物铸件表面进行打磨清理，喷漆等工序，避免了粉尘及有害物质对环境的污染及对操作人员的伤害。
