This disclosure sets out a method and apparatus for recovery of cesium formate in water solution after use in a drilling process where trash and other debris accumulate in the drilling fluid. It incorporates a first stage centrifuge, a second stage centrifuge and a membrane separator serially connected, and incorporates a feedback loop. A feedback loop iteratively redirects solids and heavy weight concentrate after processing and recycles it to enhance recovery by enhanced removal of cuttings and trash in the stream. In addition, cuttings and other solids removed from the fluid stream are introduced into a wash tank, mixed with water, and the cuttings are further processed to remove remnants of the cesium formate. These recovered cesium formate remnants are passed through an evaporator to regain the density loss attributable to the dilutive wash water. The cuttings can then be thrown away without throwing away the valuable cesium formate in the drilling solution.
