The invention relates to a processing technology for a great deal of titanium scraps produced from the processes of surface planing and milling and end surface cutting off of unpolished ingots produced from the casting of titanium ingots. The titanium scrap processing technology is a titanium scrap recycling and remelting technology which is characterized by comprising the following steps: pulverizing, screening, washing, water drainaging, drying, magnetic separating, packing, secondary drying and putting into the furnace. The titanium scrap recycling and remelting technology provides a set of processing scheme of high safety, reliability, practicability and efficiency and low cost for secondary recycling casting of the titanium scraps produced from the processes of surface planing and milling and end surface cutting off of the unpolished ingots produced from the casting of titanium, and the whole titanium scrap recycling and remelting technology is low in labor and time consumption; meanwhile, the space arra
