Basing on the ideas used by Kiselev, we study three black holes surrounded byquintessence and the effects of quintessence on the classical and semiclassicalscattering cross-sections. In contrast, the absorption section is studied withthe sinc approximation in the eikonal limit. For Schwarzschild,Reissner-Nordstr\"{o}m and Bardeen black holes surrounded by quintessence, thevalues critical of charges and the normalization factor are obtained. We alsodescribed the horizons and the extremal condition of the black holes surroundedby quintessence. By setting for the quintessence state parameter in two theparticular cases w=-2/3 and w=-1/2.
