Mineral processing technology-Upgrading
In a mineral processing plant, With upgrading we understand, the further processing of the final products from the enrichment stages in a process. This is valid both concerning the valuable minerals (the concentrate) and the waste minerals (the tailings). In the first case upgrading means improving the product value by bringing the concentrate to transportability or into a completely dry form. Processing can also go further to calcining and sintering. On the tailing side upgrading means that waste material (wash water, process effluents etc.) is properly taken care of in order to protect the environment, to recover process water and to turn certain portions into valueables. Upgrading by operation costs Upgrading has its price, increasing with the energy input for removal of the process water (or process liquid). Curves above must always be considered when we are selecting equipment for an upgrading circuit for concentrate drying or disposal of a washing effluent. ...
