Molten pig iron is converted to steel in a KOBM oxygen steel making furnace, whereas an electric arc furnace is used for producing steel from scrap steel. The steel is continuously cast as slabs up to 1.55 m wide x 0.21 m thick x 10 m long and then later processed by hot and cold rolling into pipe, rectangular hollow section and flat products.

In 2018 in Europe, a total of around 54.13 million cubic metres of sand and gravel were removed from the sea. Marine sand and gravel are generally only used when there are no appropriate deposits on land. The mining of sand and gravel in the sea is generally more expensive than on land, which is why, from a global perspective, deposits on land ...

May help to increase the economic growth of a country. In general, mining can also help to increase the overall GDP and the economic growth of a country. If more people get employed by mining corporations, people will be able to consume more products. In turn, the tax revenue as well as the profits of other companies may increase as well.

Besides sand, sea sand mining also has a by-product which is iron ore. Therefore, sea sand mining is not a new thing in various locations around the sea coast in Indonesia. In addition, sea sand mining is also carried out to conduct sea reclamation which is to accumulate large amounts of land or sand on the coast of the sea to expand …

3. Processing Chemicals Pollution. This kind of pollution occurs when chemical agents (such as cyanide or sulphuric acid used by mining companies to separate the target mineral from the ore) spill, leak, or leach from the mine site into nearby water bodies. These chemicals can be highly toxic to humans and wildlife. 4.

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.
