The Source of Gold Mneral - Its Ores and Minerals

With high market prices of minerals, gold and silver in recent months, a number of people have been asking where these minerals come from. Gold, silver and minerals that have been obtained is a mixture of diverse and different from the raw rock. Most people think of gold nuggets and Msdralamaadn such as gold, but the truth is that very little is currently Almenth gold nuggets come from - almost all come from newly mined metal ores, gold extracted from the natural rock-solid metal-containing gold in small, even microscopic particles . This article is created to describe what it is like these materials. Gold is found on the distributor on a large scale in nature, although it is one of the rarest minerals in the earth's crust. Very common, and gold, as is metal encased within the original, known as the mineral quartz. Sometimes in the case of gold grains, and sometimes in a large-size particles, and the fragments, and grains, tables, plates, wires and cables quartz in the rock. It also occurs in the case of grains disseminated through the rocks, schistose, and panels, and some sedimentary rocks such as limestone. In such cases, the rock has been altered by the flow of hot water and mineral resources, often resulting in the impregnation of large quantities of rock with silica, iron and a certain quantity of gold. Solidified rocks, sometimes even replace many, if not all of the rock country of origin. While the historical perspective and deposits have been very fruitful, these deposits are currently being published result in a lot of gold ore in the world.

Within the gold ores of gold and the same item occurs in nature mainly in the form of native gold, which is by far the most common gold bearing mineral. In various gold ore, and gold typically occurs as the original tiny particles contained in sulphide minerals such as pyrite. Iron pyrite is a very common mineral associated with gold, but it also serves as a limit. Therefore, whenever it is found encased in gold, pyrite, is always present, such as free gold is not the type of sulphide gold. Gold is also sometimes chalcopyrite, galena and arsenopyrite and stibnite, but not as a rule in large quantities of this nature was found in pyrite. Other metals, such as sphalerite, pyrrhotite, Magnetite and hematite sometimes carrying small amounts of gold as well. Gold also occurs as tellurides such as cleveite. Minerals in the good and the ores, gold, quartz, fluorite, calcite and pyrite, but many others can be found in smaller quantities.

Gold and mineral deposits:

The most prominent is the original gold - most of the original gold contains a small amount of silver, copper, platinum, metal telluride, etc. are the most common minerals containing gold in a large make-up. They include: Petite (Ag-AU) 2, T, with the gold content of about 25 per cent. He site (Ag2Te), with gold and is often put forward to replace part of the silver. Sylvain (the African Union, Ag) TE2: usually about 25 per cent. Gold. Cleveite (the African Union, Ag) TE2: usually about 40 per cent, and gold. Krennerite (Ag2Te, Au2Te3): gold, about 35 percent. Nagy agite (Au2, Pbi4, Sb3, Te7, S7). Some samples of Nagyagite gave the analysis of 12.75 per cent of gold. Sulphide containing gold, as well as telluride’s, is to form the primary, and despite the golden chalcopyrite may also be formed by secondary uranium. Original gold may occur in primary and secondary enrichment, or areas of oxidation. And telluride’s, which are usually associated with pyrite, which are disseminated widely, although not abundant, but not always recognized, even by some of the miners, they are mistaken sulphides.

Broad types of gold ores:

Gold deposits often Matson according to their association. The first of these can be classified as quartzes. This means that wheat is a mineral acid, and this is quartz, which may abound Fluorite, or even from the gangue and other minerals in the alkaline earth group. It is not rare and there appears within the different amounts of quartz, pyrite and even limited amounts of chalcopyrite and galena. These are the lines grinding materials. Of grinding ore free, is one means that the rock does not require baking before the gold can be recovered from it. Dry ore is a term often used for this category. The second layer of gold ore and copper gold. These are distributed widely throughout the United States and many of chalcopyrite is to take gold. This copper and gold particularly abundant in the state of Colorado, Utah, Montana and British Columbia. They also exist in the Gold Hill, North Carolina and Newfoundland in Canada. The third category of gold ore and raw materials, gold lead. Proportion of lead in these rocks is large and often small-scale gold content. Are refractory ores such as copper? Thermal ore is meant one requires roasting before processing extraction. And sulphides and heavy copper lead and tin that require this method of treatment, and this is the condition of the gold in the metal will not allow to capture the immediate recovery, with most systems. The fourth layer of gold ore group includes gold telluride. Gold telluride ores occur with silver or with silver, lead, tin, and gold original or accompanied by other tellurides. These materials are often sent directly to smelters for treatment. The fifth type is to spread the type of stuff. They are often low grade but great. They fill a large fracture and fault zones or replace some of the geological prospects. It is a result of the circulation of large quantities of subterranean water, hot.
