Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
What is a mineral resource? a) any rock or mineral that is useful to humans b) minerals that contain useful metals c) sand and clay minerals used in construction d) any rock or mineral that is non-organic e) rock body containing economically valuable minerals.
Slurry from the grinding circuit, at approximately 35% solids and 80—85% passing 135 mm is pumped to three thickeners Thickener underflow, at approximately 54% w/w solids, is pumped to a train of four acidulation tanks Sulfuric acid is added to the slurry to destroy sufficient carbonate prior to entering the autoclave circuit Process air is also injected into the acidulation tanks to aid.
from the gangue (tailings) In mineral processing operations for instance (gold, copper, zinc etc,) processing can be much more complex Often crushing is used along with grinding and density based and chemical separations One of the reasons that mineral processing operations involve a more complex processing plant is because the mineral.
