The invention relates to a method for efficiently removing light impurities in dust in the dust removal process. The method comprises the following core steps: mounting a blocking and collecting device containing an impurity collector and a filter material barrel on a dust removal pipeline; dusty air enters and exits from the cylindrical collector through a special pneumatic valve, and light impurities are intercepted by an internal blocking component; after the impurities are accumulated to a certain amount, a cleaning program is started, and the impurities are blown into a filter material barrel through back flushing for filtering and collecting; and finally, when the impurities in the filter material barrel are enough, the impurities are quickly discharged through the pneumatic valve at the bottom. The device is reasonable in design, simple to operate and high in practicability, and has a good market popularization prospect. Impurities in raw material ore are effectively intercepted and collected in the pr
