Abstract treasure The processing of the industrial wastes such as the petroleum ash which containing substantial quantities of toxic and/ or valuable components becomes an absolute necessity for their separation. The recovery or separation of such elements can be attained for two important aspects namely: the economical one to save raw materials and the second is the protection of the environment from dispersed toxic compounds. Therefore, studies are being carried out aimed to develop new or modified hydrometallurgical processes for the separation of metals such as: V, Ni, U, Zr and Hf. To achieve this aim the author construct the suitable plan of work to leach, determine, extract and separate the valuable elements from petroleum ash samples. |
