stripping overburden limestone mining

Surface Limestone Mining: The basic elements of surface mining are overburden removal, drilling, blasting and hauling ore to the crushing and processing plant. The selection of surface mining equipment varies with the particular requirements at each operation, including production capacity required, size and shape of the deposit, haul distances

Processing of Chromite Overburden by Soda Roasting

2021-6-17  Sukinda overburden is dumped with chromite ore tailing which contains about 17% Cr2O3. The other constituent with overburden is iron, silica and alumina. Because of its complex nature and large amount of gangue material it is not suitable for the extraction of valuable chromium by conventional route.

2011-2-16  Large quantities of soil and overburden or waste rock may need to be removed to expose the target mineral. This should be stored in pre-planned designated areas as “earth bunds”, and designed according to the geotechnical properties of the material. Overburden material should be used as infill during mine progression. Topsoil must be stored for future site rehabilitation.

2020-10-8  Most open-cast mines require the removal of overburden and waste material to access the underlying orebody. This activity is known as ‘stripping’. By their nature, all open pits become narrower with depth, and consequently the volume of waste to be stripped is largest on the upper benches that must be mined first. The problem is []

Generally, around five tons of overburden must be displaced to mine a single ton of ore. Overburden mining is not subjected to any chemical processes; however, overburden still needs to be removed to reach the mineral ores.
