The dealer is â¦ always the Big Blind. Other then these rules, the game runs in the same way as 6 or 9 handed poker. Everything else is the same. Just deal cards to 2 players instead of the amount you usually play with. It is also known as heads-up.
Currently magnetite iron ore is mined in Minnesota and Michigan in the U.S. , Eastern Canada and North Sweden. Magnetite bearing banded iron formation is currently mined extensively in Brazil, which exports significant quantities to Asia, and there is a nascent and large magnetite iron-ore industry in Australia.he ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH) , 62.9% Fe), limonite (FeO(OH).n(H2O)) or siderite (FeCO3, 48.2% Fe).
Coltan, short for Columbite-tantalite is a metallic ore comprising Niobium and Tantalum, found mainly in the eastern regions of the Democratic Republic of Congo (formally Zaire). When refined, coltan becomes a heat resistant powder, metallic tantalum which has unique properties for storing electrical charge.Of the 525 tons of tantalum used in the USA in 1998, 60% was used in tantalum capacitors, with a predicted growth rate of 14% per annum (from Uganda Gold Mining Ltd web site).t is therefore a vital component in the capacitors that control current flow in cell phone circuit boards. Mining Coltan. Coltan is mined by hand in the Congo by groups of men digging basins in streams by scrapping off the surface mud.
