Abstract A zinc recovery system was developed to recover zinc from dilute zinc sulfate lost both when acid spun yarns are washed and at various stages in the spinning process. The process included neutralization of the waste stream to pH 6.0, sedimentation of insolubles, crystallization of zinc hydroxide in a high pH environment, sedimentation of zinc hydroxide and solubilization of the zinc with sulfuric acid. A pilot plant was constructed and operated. It obtained 98-99% removal efficiency. The zinc hydroxide sludge was easily concentrated. Operating and maintenance costs were estimated. Recovery and sale of 2000 lbs of zinc daily assures recovery of these costs.
