摘　　要：根据一水硬铝石浮选精矿双流法溶出中硅钛矿物反应规律,首次提出停留罐脱硅脱钛减缓结疤技术,并将该技术成功应用于生产,减缓溶出矿浆结疤速度,延长溶出系统运行周期,减少直接加热造成的矿浆冲淡。According to the reaction kinetics of the silicon and titanium minerals in double - stream digestion process using concentrates floated from diasporic bauxite, a new process for desilication and removal of titanium using holding tanks is firstly proposed and successfully implemented. Scabbing rate in the digestion is slowed down, the running period is prolonged, and dilution caused by direct heating is reduced.
