Mind the Mine

Steve's picture

   “If you didn’t grow it, you mined it,” I’ve heard said.  Many countries of the world heavily depend on mineral extraction to keep their economies afloat.  Brazil, the locale for this blog, is no exception.  Iron ore is Brazil’s leading export. Brazil ranks third in the world in this regard, just behind China and Australia.  Multinational Vale S.A. dominates Brazil’s diversified metal industry. Vale S.A. holds about half of Samarco S.A., an iron ore extraction company.

   Around 2002, in the Brazilian State of Minas Gerais, Samarco initiated the Bento Rodrigues mine, an open pit style operation.  The iron ore facility grew steadily in size and scope for the next thirteen years. Open pit mines typically produce vast amounts of waste material and contaminated water.  Often “tailing dams” are built near the diggings to dispose of the waste material and retain potentially toxic water for eventual release or re-use.  As the mine grows, tailing dams do too, being periodically increased in height and width.

   In haste to get on with the business of mining, tailing dam safety occasionally gets relegated to a lower spot on the list. Haste may have been a factor when, on November 5, 2015, Samarco-owned tailing dams at the Bento Rodrigues facility failed.  Within just a few minutes, 70 million cubic meters of sludge-laden water escaped confinement and headed straight for the small town of Bento Rodrigues just a kilometer below.  The result was horrendous.  Muddy water nearly 20 m deep flooded the village. In the mucky morass, some 19 people died. Moreover, towns located on the Rio Doce for 900 km downstream suffered from the 17-day trek of the toxic mud’s run to the ocean. Safe to say, litigations will continue for years against Samarco for its failure to “Mind the Mine.”

These mining give good profits and increase the economic status of the country. As per uk.bestessays report the export of mines are very good business for countries around the world. For the sake of money and economic conditions they are spoiling the nature and destroying the earth core which is very harmful for the human life this may lead us to demolishing of earth also.

Based on my experience of working with The Academic Papers, I guess that making decisions on your own is the only way that people should adopt without relying on other people.
