The invention discloses a kind of silicate copper oxide chemical deposition-hydrophobic surface modified flotation method. The method includes two stages of heating chemical deposition in the early stage and hydrophobic surface modified flotation in the late stage. Firstly, the ore is crushed and ground, and then coarse separation is carried out through the vibrating screener. Qualified particle grade products enter the hydrocyclone in order to remove the mineral mud that effects the follow-up treatment of the pulp. Qualified particle grade pulp is enter the chemical deposition solution configured in the previous stage for heat treatment. After chemical deposition, the treated pulp was cooled to room temperature, that added xanthate to the pulp to modify it surface hydrophobic. In this way, the silicate copper oxide in the pulp can be recovered by flotation effectively. In this process, the silicate copper oxide surface is treated by chemical deposition, forming a copper oxide film on the mineral surface. The silicate copper oxide minerals are wrapped in it, resulting in a substantial increase in the mineral surface and the subsequent copper active sites involved in xanthate hydrophobic modification, and these active sites are stable, so the xanthate adsorption on the mineral surface is also a substantial increase, so that the silicate copper oxide hydrophobic floating. Compared with conventional flotation, this method is simple in operation, strong in adaptability, and it can effectively realize the flotation recovery of silicate copper oxide.
