Research activities have been done to make nano size particles of hydromagnesite fromdolomite mineral with ultrasonic milling equipment in the aquabident media or ethanol abosulte media orethylene glycol media. In the research work the raw material of hydromagnesite was obtained from theextraction process of dolomite mineral with partial calcination, hydrationand carbonization processes. The firststep of the process was runin 40 minute. The first experimental result showed that the best contotion ofultrasonic millingprocesswas in the ethylene glycol media. It can be evidenced from the increasing oftemperature and result of SEM anaslysis. The final result can be concluded that in the ethylene glycol media canproduced nano particle size of hydromagnesite e e e in the suspension. Particle size analysis using Delsa Nanoshown that the process wich will held in ethylene glycol media with 16 minute for run time will produce that bestsize (23 – 95) nm.
