Nano-CaCO 3 was producted by using carbide slag in the self-designed jet-reactor. The effect of different operating parameter such as CO 2 flow rate and concentration, liquid flow rate and concentration of Ca(OH) 2 on the CaCO 3 particle size and morphology has been investigated in this paper. The obtained calcite particle were characterized using x-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that the calcite about 50–200 nm was obtained under the reaction conditions of the saturation of calcium hydroxide as 1, the flow rate as 1.5 l min −1 , the CO 2 flow rate as 50 ml min −1 , the concentration as 100%, and the SDS amount 2%.
