The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.
Sand mining is the process of extracting sand from an open pit, sea beaches, rivers and ocean beds, river banks, deltas, or inland dunes. The extracted sand can be used for various types of manufacturing, such as concrete used in the construction of buildings and other structures.

Illegal Sand Mining in South Africa | SAIIA. Natural sand from estuary and coastal land is one of South Africa''s most valuable resources. However, there has recently been a drastic increase in uncontrolled and unauthorised sand mining activities in rivers, valleys and estuaries throughout the country.
Ironsand, also known as ironsand or iron sand, is a type of sand with heavy concentrations of is typically dark grey or blackish in colour. It is composed mainly of magnetite, Fe 3 O 4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.. Ironsand has a tendency to heat up in direct sunlight, causing temperatures high enough to cause minor burns.
Different mining methods (mechanical or manual) are adopted for the extraction of sand from these sources under dry (above water table) and/or wet (below water table) conditions. This chapter describes briefly the different sources, methods and hydrogeological bearings of sand and gravel extraction processes in river ecosystems.
The flotation process is primarily used to remove the iron bearing heavy minerals in silica sand. The minerals are generally the same as the iron bearing minerals described in the gravity section. At times, flotation can also be used to remove mica. Magnetic Separation. In silica sand mining process, various magnetic minerals are involved in it.
Sand mining is the extraction of sand, mainly through an open pit (or sand pit) but sometimes mined from beaches and inland dunes or dredged from ocean and river is often used in manufacturing, for example as an abrasive or in is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface.

While no international conventions regulate the extraction, use and trade of landbased sand (sand quarry, riverine and lake aggregate), the United Nation Convention on the Law of the Sea, 1982 (UNCLOS) provides for the delimitation of maritime zones and regulates rights and obligations in respect of usage, development and preservation for these zones, including resource mining.
process of mining the iron sand Iron ore is magnetically separated from the sand, whilst other minerals are extracted by sieving, before returning the residue back to the sea. 3442 The sand mining methods used will vary, depending on the depth of the seafloor where the sand is being extracted from, and the distance from shore.

The iron ore concentrate makes up about 10 per cent of the iron sand and the remaining sediment is returned to the seafloor. Export. The iron ore concentrate will be stored temporarily in the IMV before being transferred as slurry to the transshipment vessel. Fresh water from the desalination plant will be used to rinse salt from the iron ore.
