Gold Cyanidation In Romania
Gold cyanidation is a chemical process for extracting gold from low-grade ore. Used in Romania for decades, the process came into debate following the 2000 Baia Mare cyanide spill and proposal of the Roșia Montană Project, which would create the largest operation for gold extraction using cyanides in Europe. Exploitation projects Currently, there is no exploitation project active, but there is one that has its operations suspended temporarily (Baia Mare) and there are two proposed projects (Roșia Montană and Certeju de Sus, Certej). Previously, there were also exploitations in Baia de Arieș (Alba County), Sasar, Suior, Cavnic, Tăuții-Măgherăuș, Băița, Băiuț (Maramureș County). There are some ongoing explorations projects operated by Eldorado Gold in Brad, Hunedoara, Brad, Deva, Romania, Deva and Muncel, Hunedoara, Muncel (Hunedoara County), in addition to the company's new intended exploitation in Certej.

Gold Cyanidation
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver, usually after froth flotation. Production of reagents for mineral processing to recover gold represents more than 70% of cyanide consumption globally. Other metals are recovered from the process include copper, zinc, and silver, but gold is the main driver of this technology. Due to the highly poisonous nature of cyanide, the process is controversial and its use is even banned in some parts of the world. Cyanide can be safely used in the gold mining industry. A key feature for safe use of cyanide is to ensure adequate pH control at an alkaline pH level above 10.5. At industrial scale, pH control is mainly achieved using lime, as an ...

Danube
The Danube ( ; ) is a river that was once a long-standing frontier of the Roman Empire and today connects 10 European countries, running through their territories or being a border. Originating in Germany, the Danube flows southeast for , passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine before draining into the Black Sea. Its drainage basin extends into nine more countries. The largest cities on the river are Vienna, Budapest, Belgrade and Bratislava, all of which are the capitals of their respective countries; the Danube passes through four capital cities, more than any other river in the world. Five more capital cities lie in the Danube's basin: Bucharest, Sofia, Zagreb, Ljubljana and Sarajevo. The fourth-largest city in its basin is Munich, the capital of Bavaria, standing on the Isar River. The Danube is the second-longest river in Europe, after the Volga in Russia. It flows through much of Central and Sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tisza
The Tisza, Tysa or Tisa, is one of the major rivers of Central and Eastern Europe. Once, it was called "the most Hungarian river" because it flowed entirely within the Kingdom of Hungary. Today, it crosses several national borders. The Tisza begins near Rakhiv in Ukraine, at the confluence of the White Tisa and Black Tisa, which is at coordinates 48.07465560782065, 24.24443465360461 (the former springs in the Chornohora mountains; the latter in the Gorgany range). From there, the Tisza flows west, roughly following Ukraine's borders with Romania and Hungary, then shortly as border between Slovakia and Hungary, later into Hungary, and finally into Serbia. It enters Hungary at Tiszabecs. It traverses Hungary from north to south. A few kilometers south of the Hungarian city of Szeged, it enters Serbia. Finally, it joins the Danube near the village of Stari Slankamen in Vojvodina, Serbia. The Tisza drains an area of about and has a length of Its mean annual discharge is seas ...

Tailings Pond
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1971 Certej Dam Failure
The 1971 Certej dam failure was a flood due to the failure of a tailings dam at the Certej mine which led to the death of 89 people. It occurred on 30 October 1971 in Certeju de Sus commune, Hunedoara County, Romania. Background The tailing pond of Certej was used between 1936 and 1971 to hold the cyanide-laced acid tailings resulting from the gold mine exploitation of Certej. The disaster At 4:55 AM, the dam broke for a length of and from the tailings pond, of residue flowed towards the town of Certej, flooding a radius of around around the pond. The flood completely destroyed six apartment buildings, a dormitory building and seven individual houses, resulting in 89 deaths and 76 people being wounded. Due to the early hour, most of the victims were sleeping, which resulted in the high death toll. Aftermath The Romanian Communist authorities announced in the press only 48 deaths, in order to avoid a National day of mourning. The survivors were compensated for the loss of th ...

Democratic Union Of Hungarians In Romania
The Democratic Alliance of Hungarians in Romania (DAHR; hu, Romániai Magyar Demokrata Szövetség, RMDSZ; ro, Uniunea Democrată Maghiară din România, UDMR) is a political party in Romania which aims to represent the significant Hungarian minority of Romania. It has been described as having close ties with Hungary’s socially-conservative ruling Fidesz party. Officially considering itself a federation of minority interests rather than a party, from the 1990 general elections onwards the DAHR has had parliamentary representation in the Romanian Senate and Chamber of Deputies. From 1996 onwards the DAHR has been a junior coalition partner in several governments. The party is a member of the European People's Party (EPP) and Centrist Democrat International (CDI). History The UDMR was founded on 25 December 1989, immediately after the fall of the Communist dictatorship in the Romanian Revolution of 1989 to represent in public the interests of the Hungarian community ...
