impure gold, as it commonly occurs in deposits, has a density of to 18, whereas the associated waste rock has a density of about 2.5. the differ-ence in density enables gold to be concentrated by gravity and permits the separation of gold from clay, silt, sand, and gravel by various agitating and
mining waste metal mining.. has significant volume of waste rock materials that need to be shifted and managed. major mining waste comprises the following: waste rock, tailings, acid rock drainage, fueloilgreases, dust and silt, sewage, sulphur and toxic gases given out from the mill chimney.
underground mining has the potential for tunnel collapses and land subsidence It involves large-scale movements of waste rock and vegetation, similar to open pit mining. additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.
comminution circuits are used to optimize the liberation of valuable mineral particles from waste rock for downstream separation processes. when the target grind is not achieved it results in a higher number of unliberated gold particles. this in turn causes a loss in gold recovery and therefore revenue.
the amount of waste rock that needs to be removed depends on the geometry and location of the ore body, along with the mining method used and the composition and stability of the rocks. the ratio between waste rock and ore production is called the stripping ratio. for example, a stripping ratio of means that tonnes of waste rock needs to
