Copper alloy ingot compounding and recycling process

The invention discloses a copper alloy ingot compounding and recycling process. The copper alloy ingot compounding and recycling process comprises the following steps that copper alloy ingot is pouredinto a rotary kiln with temperature of 250 DEG C for baking, and the liquid in the copper alloy ingot is gasified or carbonized in the rotary kiln, and the dried copper alloy ingot falls into the bottom of the rotary kiln to obtain the dried copper alloy ingot; uniform mixing KCl, NaCl and Na3AlF6 according to the weight ratio, KCl: NaCl:Na3AlF6=11:6:3, so as to prepare a covering agent; then adding a copper liquid into a smelting furnace, and the adding amount of the copper melt is not less than 35% of the total volume of the smelting furnace; then adding the copper alloy ingot, and stirringby a stirrer; the temperature of the copper melt in the smelting furnace is 760 DEG C +/-10 DEG C; adding the copper alloy ingot, adding the covering agent into the smelting furnace every half hour,the adding amount of the co
