Abstract: A method for froth-controlled flotation of argillaceous lepidolite ore, including: crushing and grinding an ore, adding water to obtain pulp; adding agents thereto, and conducting roughing to obtain roughing concentrate and roughing tailing; adding agents to the roughing tailing, and conducting first scavenging to obtain first scavenging concentrate and first scavenging tailing; subjecting the first scavenging tailing to second scavenging to obtain second scavenging concentrate and second scavenging tailing; adding agents to the roughing concentrate, conducting first cleaning to obtain first cleaning concentrate and first cleaning tailing; subjecting the first cleaning concentrate to second cleaning to obtain lithium concentrate I and second cleaning tailing; combining the first scavenging concentrate, second scavenging concentrate, first cleaning tailing, and second cleaning tailing to obtain lithium-containing mixed middling, adding agents thereto, and conducting cleaning-scavenging to obtain lithium concen
