Abstract: In order to find reasonable parameters for carbon-containing briquettes made from a coastal placer，with iron grade of 51.85% and TiO₂ contents of 11.33%.Using coal slime as the reductant，wet ball drop strength，dry ball compress strength as evaluating criteria，effects on dosage of coal slime，water content，granularity of raw ore，types and amount of binder are researched.Results show that using coal slime as reductant compared with originally bituminous coal，the drop strength of wet ball dropped increased from 3.7 N/P to 17.8 N/P，the comprehensive strength increased from 164 N to 214 N；briquettes with drop strength of wet ball over 16 N/P，comprehensive strength of dry ball is 492 N can obtained with conditions of coal slime dosage is 30%，water content is 7%，CMC addition of 0.3%.For the advantages of higher ash content，finer granularity，higher viscosity，coal slime provides a new method in high efficient utilization of China's beach titanomagnetite.
