The invention relates to a flotation method for silico-calcareous collophanite without the help of a tailing pond, and belongs to the technical field of mineral processing. The flotation method comprises the following steps of: crushing raw ores, feeding the crushed ores into a fine ore bin, performing primary grinding classification operation, feeding overflow of classification operation into a reverse flotation stirring operation, and feeding the overflow into a reverse flotation roughing operation pulp washing tank; performing first-stage dehydration operation on flotation froth and slurryin a flotation tank, and feeding filtrate into a reverse flotation return water sedimentation tank; feeding a filter cake into second-stage ore grinding classification operation, feeding overflow of classification operation into a direct flotation operation stirring tank for direct flotation operation, feeding filtrate obtained after slurry dehydration in the tank into a direct flotation return water sedimentation tank, a
