The site experiment of grade combinated leaching technique of high-mud oxidated ore

It is the key to seek the simple technology to leaching high-mud oxidated ore, which has the bad effect in heap leaching, to heighten leaching efficient and reduce cost. After fully analyzing and technological reforming, the combined leaching technology is coming forth, with which heap leaching is mostly and stir leaching is subsidiary. By using breakage and washing classification technology, ore is divided to the clay and massive mineral which enter into different process flow. With the strap transforming ore to pile, dynamic using acid technology, permeability of heap is improved and the consumption of acid is reduced. Under the waste heat to heat stirred leaching and densing technology of pulp, which is taking place of pulp heating and leaching residue filtrated technology respectively, the process then is simplified and the energy consumption saved. Classification combined leaching technology is adaptable, and breakthrough the bottles of high-mud oxided ore leaching.
