A method for preparing copper indium gallium alloy powder, comprising: smelting, in a smelting crucible, copper, indium, gallium and recovered copper indium gallium alloy powder having a particle size not within a set range, to form an alloy solution; atomizing, cooling and sieving the alloy solution to obtain copper indium gallium alloy powder having a particle size within the set range; and recovering copper indium gallium alloy powder having a particle size not within the set range. In the smelting step, indium and gallium are placed at the bottom of the smelting crucible, copper is mixed with the recovered copper indium gallium powder having a particle size not within the set range, and then placed above the indium and gallium in the smelting crucible. Said preparation method reduces the energy consumption cost and production cost, and the risk of element component deviation caused by the burning loss of a low-melting-point element, reducing the waste of the element, and improving the ...
