Extraction of Nonferrous Metal

Once the ore is mined, the raw ore is firstly crushed and milled to expose auriferous minerals (mainly native metal). Before leaching, the grain size is prepared to 0.4mm, 74μm or 44μm depending on the leaching test result. In case the raw ore is highly oxidized or of too much slurry, hydrocyclone and thickener are used to remove slurry.
