What are tAILingS. Put simply, tailings are ground up rock minus the gold. Rocks mined from underground which contain gold are called ore. Processing involves crushing the ore into sand to liberate and recover the gold. What's left over is called tailings. Approximately 95% of the tailings are generated from gravity separation methods, which ...

CIL (Carbon In Leach), the gold carbon leaching method, is the carbon leaching method for gold extraction. Normally, the CIL process can concentrate gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t in carbon. The CIL gold process is suitable for beneficiating oxidized gold ore with low sulfur and mud content; Or process the gold tailings ...

The tailings reprocessing method is suitable for the re-separation of various tailings, including gold, iron, lead-zinc, copper, fluorite, tungsten, phosphorus, graphite, bauxite tailings, etc. Among them, a centrifugal concentrator is usually used to process gold tailings, so that valuable ore can be separated due to its higher density. 4.

Gold Ore Mining. Placer gold mining mainly refers to mining from the land surface or river or underground. It mainly uses gravity separation because its density is much bigger than other minerals.
