Methods for reducing wear in pumping components during fracturing operations. A coated proppant is used that causes less wear on the pumping components as the proppant is pumped into the wellbore. The proppant coating consists of a substrate having a coating thereupon which eliminates sharp edges on the substrate and functions as a lubricant to materially reduce mechanical erosion of the pumping components. The proppant substrate may consist of any of a number of materials, including sand, ceramic, resin coated sand, or resin coated ceramic particle. The coating preferably comprises one or more layers of one or more of the following materials (or the coating having low friction coefficients is part of a mixture of the coating): antimony trioxide, bismuth, boric acid, calcium barium fluoride, copper, graphite, indium, fluoropolymers (FTFE), lead oxide, lead sulfide, molybdenum disulfide, niobium dielenide, polytetrafluoroethylene, silver, tin, or tungsten disulfideor zinc oxide. The coating material may be applied to the substrate in a number of ways known in the art.
