The invention discloses a preparation method of a pyrite tailing ceramsite proppant. Pyrite tailings are subjected to calcination pretreatment and petroleum drilling effluent steeping, the composition and content of raw materials from which ceramsite is prepared are optimized, the physical and chemical performance of the ceramsite is adjusted, and then the pyrite tailing ceramsite proppant with high pressure resistance and low density is prepared. 本发明公开了种硫铁尾矿陶粒支撑剂的制备方法，通过对于硫铁尾矿进行煅烧预处理、石油钻井废液浸渍、再优化制备陶粒的原料组成及其含量，调节陶粒的物化性能，制备出耐压强低密度的硫铁尾矿陶粒支撑剂。
