How to Extract Gold From Ore? Mining Pedia
2022-2-11 The percolation cyanidation method is also one of the cyanide leaching processes. Its principle is that the cyanide solution penetrates through the ore layer to leach the gold from the gold-bearing ore. It is suitable for alluvial and loose porous materials. There are two kinds of percolation cyanidation methods: pool leaching and heap leaching.
