leaching mining process

leaching mining process

Jan 10 2019 · Heap leach mining is an industrial hydrometallurgical process where the metal contained in an ore body is extracted by dissolution The target mineral is leached with an aqueous solution whereby the mineral is dissolved into what is called a “pregnant” solution which is then captured and later recovered downstream in the processing line
