According toDrVixamar, Haiti possesses the most and best gold than any other country in the world Iridium alone will economically develop Haiti.

Besides the iridium in Beloc,DrHenry VIXAMAR says there is Iridium also in Benet, Haiti. Iridium was first discovered in 1803 by Smithson Tennant. Iridium appears as symbol Ir on the periodic table and has an atomic weight of 192.217 and a density of 22.56 g/cm, making it the. From soluble extracts, iridium is separated by precipitating solid ammonium hexachloroiridate ((NH4)2IrCl6) or by extracting IrCl26 with organic amines. The evidence comes from unusually high levels of iridium in rocks 66 million years old. According to a report of the Paris Exhibition of 1867, one of the pieces being exhibited by Johnson and Matthey "has been used in a Whitworth gun for more than 3000 rounds, and scarcely shows signs of wear yet. Will the nation benefit or suffer more if mines are built for extraction of iridium and similar resources?, Iridium complexes are often active for asymmetric hydrogenation both by traditional hydrogenation. During electrorefining of copper and nickel, noble metals such as silver, gold and the platinum group metals as well as selenium and tellurium settle to the bottom of the cell as anode mud, which forms the starting point for their extraction. ![]() Check your inbox or spam folder to confirm your subscription. The first method is similar to the procedure Tennant and Wollaston used for their original separation. The first use of an alloy of iridium with ruthenium in thermocouples was made by Otto Feussner in 1933. Illustrative factors that affect the price include oversupply of Ir crucibles The key to that success was a discovery in Haiti of an unusually thick sequence of impact ejecta. Since 1944, the famous Parker 51 fountain pen was fitted with a nib tipped by a ruthenium and iridium alloy (with 3.8% iridium).

Recently, the Canadian company Majescor purchased the rights to explore 450 square km in Haiti and its stock doubled in the single day after it reported high levels of gold in its drill samples.A very hard, brittle, silvery-white transition metal of the platinum group, it is considered the second-densest naturally occurring metal (after osmium) with a density of 22.56 g/cm 3 (0.815 lb/cu in) as defined by experimental X-ray crystallography. Since 2012 gold and copper mining in northern Haiti increased. The government of Haiti received about $3 million. The copper ore was valued at about $83.5 million. Half a million tons of ore were exported. (“Halliwell”), a Canadian corporation, through its wholly owned Haitian subsidiary, La Societe d’Exploitation et de Developpement Economique et Natural d’Haiti (“Sedren”) mined copper near Gonaïves. Operating from 1960 to 1972 International Halliwell Mines, Ltd. Bauxite was mined for a number of years in recent times at a site near Miragoâne on the Southern peninsula. Gold was mined by the Spanish in early colonial times. Lime and aggregates and to a lesser extent marble are extracted. Bauxite, copper, calcium carbonate, gold, and marble were the most extensively extracted minerals in Haiti. Haiti has a mining industry which extracted minerals worth approximately US$20 million in 2019.
