Disclosed is a method for preparing a catalyst precursor for methanol synthesis using copper sulfate recovered from low-cost copper etching waste solution as the source of copper, which comprises using recovered copper sulfate containing the mother liquor in the amount of 10% by weight or less, and adding a zinc or aluminum compound, and, if necessary, further adding a boron compound to the recovered copper sulfate. A catalyst capable of developing all of the characteristics of the catalyst prepared with an expensive starting material such as the conventional metal nitrates can be prepared and the catalyst cost can be reduced to a great extent, thus giving it great industrial value. |
