Study on Factors Affecting Iron Removal from Kerf Loss Slurry Waste Using Acid Leaching

Jiangshan Z, Zhengyi J*, Jing G, Jingwei Z and Zhixin C

It is significantly valuable to recover silicon and silicon carbide powder from kerf loss slurry. Iron fragments undermine both the performance of cutting efficiency and the quality of recycled powder, thus requires to be removed. The current study is to shed lights on the effect of the several physico-chemical parameters on the efficiency of iron removal during acid leaching. The significance of each parameter is studied using the method of analysis of variance. The results show that the acid leaching is an effective technique to remove iron by investigating the theory and practice. Leaching duration is a dominant parameter to determine the leaching rate, followed by the effect of temperature and acid concentration.
