摘要：

The use of recycled paper is increasing worldwide. The slushing and flotation cell operations are greatly affected by the operating conditions, chemicals used and type of raw material. In this study old uncoated magazines (OMG) have been used with different operating conditions and concentrations of NaOH, Na2SiO3 H2O2 and active chemical as surfactant. The effects on yield, deinkability factor, brightness and opacity are estimated for the changes in operating conditions and dosages of additives, to a reasonable extent. It is found that at 65°C, 6% consistency and proper chemical compositions, good quality acceptable pulp can be obtained.
