The invention provides a white copper alloy solution smelting technology. The technology comprises the following steps that firstly, compositions of a white copper alloy comprise, by mass percent, 9.0-11.0% of Ni+Co, 1.0-1.5% of Fe, 0.5-1.0% of Mn and the balance copper, the sum is 100%, and raw materials are prepared according to the compositions of the white copper alloy; secondly, the raw materials are added into a power frequency induction furnace, the surfaces of the raw materials are covered with charcoal, and smelting is carried out, and alloy liquid is obtained; thirdly, oxygen is introduced into the power frequency induction furnace, time is 2-10 min, P is reduced and gasified into P2O5, and degassing is carried out; and fourthly, a deoxidizing agent is added into copper liquid, and the copper liquid stands and is refined to obtain white copper alloy solution. According to the white copper alloy solution smelting technology, white copper is added into returned materials in thered copper TP2 technolog
