Fiber loss is a major concern in deinking operations. In the current laboratory investigation, ledger grade paper underwent a laboratory deinking process that included alkaline pulping, screen washing and dispersed air flotation, High levels of clay added into the flotation cell significantly decreased the fiber loss in the flotation rejects. Yet, the clay added did not interfere with flotation deinking performance as measured by brightness, dirt count and Effective Residual Ink Concentration.
