The relative abundances of He, C, O and Fe ions with energy of ~0.04-0.16 MeV/nucleon in fluxes from near-equatorial coronal holes (CHs) were equal to abundances of thermal ions from CH and showed the good resemblance in dependences on solar wind velocity in the SC 23 and SC 24 as well. The intensities of the suprathermal 3He, 4He, C, O, and Fe ions in outflows from CHs increased with the speed of the solar wind. The results obtained suggest that the sources of suprathermal ions from CHs in periods of low solar activity are accelerated solar wind particles forming a continuously present high-temperature “tail” of the solar wind.
