The foam zone is an important section in flotation dynamics, serving as a process for the final separation of useful minerals from gangue minerals. It controls the yield of the product, the grade of the concentrate, and the ultimate recovery rate. In this study, three typical minerals were selected for the analysis and research of their foam characteristics. Through radial foam sampling tests, foam mobility tests, foam load calculations, and reagent system analysis, the foam characteristics of lithium mica, ilmenite, and chalcopyrite were analyzed. Based on these findings, a differentiated approach for forced recovery of foam was proposed, providing guidance for the timely and efficient recovery of flotation foam products.
