Seabed Mineral Resources

seabed mineral resourcesRussia has begun to actively compete for seabed mineral resources. The International Seabed Authority (ISA) has approved a request by Moscow to conduct geological investigations in the sources of Kommersant Atlántico.Según sea, this is one of the largest untapped deposits in the world, copper and gold contents of between five and ten times that of landline. The project will be undertaken by the Geological Survey Expedition Polar and Marine Research Center VNII Okeangeologia, and has a budget of up to 43 million dollars over the next five years. Kommersant sources in the Russian government’s initiative shows that the Russian exploration of marine resources associated with a strong intensification of China in the same sector.

Russian Natural Resources Ministry announced on August 3, that the application for the exploration of mineral resources in the seabed was filed in December 2010 and approved on July 19 during a meeting at ISA headquarters in Kingston, Jamaica. In addition to Russia’s request, which was also adopted from China and Pacific island countries, Nauru and Tonga? This is the first time in history that the ISA authority without drilling in marine waters attached to the economic zone in accordance with specific circumstances.

Dario Vasilevskaya, deputy director of the department of state policies and regulations in the field of geology and exploitation of natural resources Natural Resources Ministry, told Kommersant that the contract with the ISA will be signed at the end of 2011 and will last for fifteen years, extendable to five. Explore the region that Russia has 100 blocks, each of 100 square kilometers and is located in the northern Cordillera Centroatlántica. Supplied minerals are found at depths of 2-4 kilometers. It is understood that Russia will have priority to exploit the deposits, according to the press service the Ministry of Natural Resources. The contract will last for two public companies: Prospecting Expedition Polar and Marine Geology Research Center VNII Okeangeologia.

According to information obtained by Kommersant, this exploration plans of one of the largest gold and copper deposits in the world, which is still unexplored. “In the land given to the Russians have found six promising sites. A rough estimate of the resources is between 50 and 70 million tones of dry ore body,” he told Kommersant Sergey Andreyev, deputy director of the department of geology and mineral resources Ocean World Okeangeologia VNII. “Keep in mind that the mineral content of rocks under the water several times larger than the earth’s surface.” According to experts, the average copper content in soil is 1%, while in submarine sulfide is given to Russia could be between 2.5% and 10% on average (maximum level is 30%) and a ton of rocks containing between 4 and 10 grams of gold. (17 g per ton maximum) If this assessment is confirmed, these resources will be comparable with those of the company Norilsk Nickel (Norilsk Nickel)… Read the rest of this entry »

Mining Companies Transform Themselves Into Zinc Metal for Domestic Consumption and for Export

Mining Companies Transform Themselves Into Zinc Metal for Domestic Consumption and for ExportTwo groups of minerals are exploited mainly zinc, supplied minerals (zinc sulfide associated with lead sulfide) which represent the main source of extraction, and calamine type oxide minerals that are in danger of extinction.

Production

Zinc is the fourth-level metal production in the world after iron, aluminum and copper. Although it operates in over 50 countries, the top five producing countries (China, Australia, Peru, Canada and the U.S.) produce about 65% of world production.

The zinc ore accounts for 50% of global demand for zinc. In the United States for example, two thirds of zinc are produced from the ore while the remaining third comes from the recycling of waste and debris. The progression of the supply of zinc is driven, among other things, potential markets and strong growth in construction sector in industrialized countries since the 1970′s.

The various markets for zinc and strong growth in construction have led to increases in the consumption of this product. The main exception is Central and Eastern Europe, consumers younger than galvanized steel.

Most large mining companies transform themselves into metal zinc for domestic consumption or for export. However, the ore is also exported in its raw form to be refined in third countries such as Japan, the Republic of Korea or Spain.
