    This thesis aims to choose the best laser coating powder system among experimented materials and to estimate the useful life of specific laser coated pump parts. Slurry pumps in mineral processing are parts which erode away very quickly. Erosion is dominantly caused by abrasion from fine particles of the ore. Due to its cause, the process of erosion takes place on impeller blades and cover plates which have direct contact with the slurry. Erdenet Mining Corporation has cooperated with GMIT and Prof. Dr. Gunther Stehr for this thesis work as a project. The Corporation supplied self-produced impeller and cover plate of the slurry pump (GrAT–1400/40). This type of pump is designed in Russia. It used for delivering Copper and Molybdenum ore in Concentration Plant at Erdenet Mining Corporation. The GRAT – 1400/40 pump parts were delivered to Germany for laser coating and shipped back for trial. At Concentration Plant of Erdenet Mining Company, we used three different thermal coatings to have early research point to gain the most suitable solution as trial. Technical estimations have been done. Without changing design or base material (economically suitable material for the area), gaining higher lifetime is very important. Achieving favorable result would greatly benefit industries which specifically uses pump for delivering slurry.
