Abstract：The effects of pre-heating temperature， pre-heating time， roasting temperature and roasting time on consolidation properties of the pellet were studied to utilize PMC. The pellet was composed of PMC and the PMC mineral to Sijiaying mineral powder was 7[∶]3. Results show that， when the preheating time is 10 min， the roasting time is 20 min， and the roasting temperature is 1 275 ℃， the compression strength of the pellet increases firstly and then decreases with the increase of pre-heating temperature. When the pre-heating temperature is 925 ℃， the compression strength of the pellet reaches the maximum， which is 2 765.75 N/per. When the pre-heating temperature is 925 ℃， the roasting time is 20 min and the roasting temperature is 1 275 ℃， the compression strength of the pellet increases from 2 646 N/per to 2 833.61N/per with the increase of pre-heating time. When the preheating time is 15 min， the roasting time is 10 min and the pre-heating temperature is 925 ℃， the compression strength of the pellet increases from 674.96 N/per to 2 503.83 N/per with the increase of roasting temperature. When the preheating time is 15 min， the pre-heating temperature is 925 ℃ and the roasting temperature is 1 300 ℃， the compression strength of the pellet increases from 2 503.83 N/per to 2 872.52 N/per with the increase of roasting time.
